    ___ N.W.2d ___
    Filed March 2, 2021.     No. A-19-1194.
    1. Child Custody: Jurisdiction: Appeal and Error. The question whether
    jurisdiction should be exercised under the Uniform Child Custody
    Jurisdiction and Enforcement Act is entrusted to the discretion of the
    trial court and is reviewed by an appellate court de novo on the record
    for abuse of discretion.
    2. ____: ____: ____. In considering whether jurisdiction exists under the
    Uniform Child Custody Jurisdiction and Enforcement Act, a jurisdic-
    tional question that does not involve a factual dispute is determined by
    an appellate court as a matter of law, which requires an appellate court
    to reach a conclusion independent from the trial court.
    3. Jurisdiction: Appeal and Error. Before reaching the legal issues
    presented for review, it is the duty of an appellate court to determine
    whether it has jurisdiction over the matter before it.
    4. Jurisdiction: Final Orders: Appeal and Error. For an appellate court
    to acquire jurisdiction of an appeal, there must be a final order or final
    judgment entered by the court from which the appeal is taken.
    5. Final Orders: Appeal and Error. Among the three types of final orders
    which may be reviewed on appeal is an order that affects a substantial
    right made during a special proceeding.
    6. ____: ____. An order affects a substantial right when the right would
    be significantly undermined or irrevocably lost by postponing appel-
    late review.

    minations are special proceedings for purposes of determining whether
    an order is a final, appealable order.

    8. Child Custody: Jurisdiction. Jurisdiction over a child custody proceed-
    ing is governed exclusively by the Uniform Child Custody Jurisdiction
    and Enforcement Act.
    9. Child Custody: Jurisdiction: States. Jurisdiction over custody
    matters having interstate dimension must be determined indepen-
    dently by application of the Uniform Child Custody Jurisdiction and
    Enforcement Act.
    10. Courts: Jurisdiction. Jurisdictional priority is neither a matter of sub-
    ject matter jurisdiction nor personal jurisdiction. The subsequent court
    does not lack judicial power over the general class or category to which
    the proceedings belong and the general subject involved in the action
    before the court.
    11. Child Custody. An action concerning custody of the child is not termi-
    nated, resolved, or disposed of until the age of majority.
    12. ____. An application to modify a custody determination is not an
    independent proceeding, but is simply a proceeding supplementary or
    auxiliary to the original action in which certain matters were subject
    to modification.
    13. Judgments: Equity: Time. A litigant seeking vacation or modification
    of a judgment after term may take one of two routes. The litigant may
    proceed either under 
    Neb. Rev. Stat. § 25-2001
     (Reissue 2016) or under
    the district court’s independent equity jurisdiction.
    14. Motions to Vacate: Proof: Appeal and Error. An appellate court will
    reverse a decision on a motion to vacate or modify a judgment only if
    the litigant shows that the district court abused its discretion.
    15. Judgments: Words and Phrases. The operative definition of “irregular-
    ity” limits the term to the doing or not doing that, in the conduct of a
    suit at law, which, conformably with the practice of the court, ought or
    ought not to be done.
    16. ____: ____. A judgment marred by irregularity is one rendered contrary
    to the course of law and practice of the court.

    INTRODUCTION
    Brian L. Mann appeals the order of the Douglas County
    District Court granting the request of Asia R. Mann, now
    known as Asia R. Harrison, for partial summary judgment
    which vacated a portion of the parties’ 2018 dissolution decree
    granting Brian “in loco parentis” status over Asia’s biological
    child Maleah D. On appeal, Brian’s sole assignment of error
    is the court erred in determining that it did not have subject
    matter jurisdiction over Maleah due to the court’s erroneous
    interpretation of the Uniform Child Custody Jurisdiction and
    Enforcement Act (UCCJEA). For the reasons set forth herein,
    we affirm.
    STATEMENT OF FACTS
    In 2009, Asia engaged in a relationship with Patrick D. that
    resulted in the out-of-wedlock birth of Maleah. When Asia and
    Patrick’s relationship ended, the Superior Court of California,
    County of Ventura, entered an order in August 2010 that
    awarded Asia sole legal and physical custody over Maleah and
    granted Patrick reasonable rights of visitation.
    In March 2011, Asia married Brian, and the parties had two
    other children. In February 2016, Asia filed a complaint for
    dissolution of marriage in Nebraska in the Douglas County
    District Court. However, over 2 years later in March 2018,
    which was prior to the district court’s resolution of the parties’
    dissolution action, Patrick filed a complaint in the Douglas
    County District Court, which complaint sought to register the
    California judgment. The district court registered the California
    judgment in Nebraska in April 2018.
    Although the California judgment which set forth Patrick’s
    reasonable rights of visitation with Maleah had been regis-
    tered in Nebraska in April 2018, a few months later, in July,
    the district court resolved Asia and Brian’s dissolution action
    by entering a stipulated decree, which stated that Brian had
    acted in loco parentis to Maleah, granted Brian and Asia
    joint physical custody of Maleah, and granted Asia sole legal
    - 551 -
    Nebraska Court of Appeals Advance Sheets
    29 Nebraska Appellate Reports
    MANN v. MANN
    Cite as 
    29 Neb. App. 548
    custody over Maleah with the exception that Asia could not
    change Maleah’s school district without Brian’s consent or the
    district court’s approval. The stipulated decree also awarded
    Brian and Asia joint legal and physical custody of their two
    other children and outlined alternating parenting time between
    Brian and Asia for all three children.
    In July 2019, Brian filed a complaint to modify, and in
    August, Asia filed an answer and counterclaim which alleged
    Maleah was not a child of Brian and Asia’s marriage and
    requested modification of custody transferring sole legal and
    physical custody of the children to Asia. In September, Asia
    filed a motion for partial summary judgment, and later that
    same month, Brian filed a competing motion for partial sum-
    mary judgment, both of which related to that portion of the
    parties’ stipulated dissolution decree governing the custody
    of Maleah.
    A hearing on the competing motions for partial summary
    judgment was held in October 2019. During that hearing, the
    district court took judicial notice of the entire case file and
    received exhibits 1 through 5, which exhibits included the
    California judgment, the certified application to register the
    foreign judgment, the Nebraska order confirming the registra-
    tion of the foreign judgment, Asia’s affidavit supporting her
    motion for summary judgment, and Patrick’s affidavit support-
    ing Asia’s motion for summary judgment. No argument was
    presented to the district court on the matter.
    In November 2019, the district court entered an order grant-
    ing Asia’s motion for partial summary judgment and vacating
    its previous orders regarding Maleah, finding it did not have
    subject matter jurisdiction to make a custody determination
    governing Maleah. In its order, the district court relied on
    Blanco v. Tonniges, 
    2 Neb. App. 520
    , 
    511 N.W.2d 555
     (1994),
    for the proposition that “‘when a parent unilaterally removes
    a child from the state of a court that has rendered a decree
    concerning custody of the child, the continuing jurisdiction
    of the prior court is exclusive, and other states do not have
    - 552 -
    Nebraska Court of Appeals Advance Sheets
    29 Nebraska Appellate Reports
    MANN v. MANN
    Cite as 
    29 Neb. App. 548
    jurisdiction to modify the custody decree.’” (Emphasis omit-
    ted.) The district court articulated that the California court
    made the initial custody determination concerning Maleah,
    and had not relinquished its continuing exclusive jurisdic-
    tion, and that a significant connection to California remained
    because Patrick continued to reside there. The district court
    also noted that the parties could not waive a defect in subject
    matter jurisdiction, especially when Patrick was not a party
    to the present case. Additionally, the district court found that
    granting Brian in loco parentis status had a significant effect
    on Patrick’s rights.
    Finally, the district court determined that it did not have
    jurisdiction to modify the California judgment or to make an
    initial custody determination regarding Maleah, and it sus-
    tained Asia’s motion for partial summary judgment and vacated
    that part of the dissolution decree which had granted Brian
    in loco parentis rights over Maleah. In December 2019, the
    district court clarified its order by denying Brian’s motion for
    partial summary judgment and voiding everything pertaining
    to the custody and parenting time of Maleah in its earlier dis-
    solution decree due to the district court’s lack of subject matter
    jurisdiction. Brian has timely appealed to this court.
    ASSIGNMENT OF ERROR
    Brian’s sole assignment of error is the court erred in
    determining that it did not have subject matter jurisdiction
    over Maleah due to the court’s erroneous interpretation of
    the UCCJEA.
    STANDARD OF REVIEW
    [1,2] The question whether jurisdiction should be exercised
    under the UCCJEA is entrusted to the discretion of the trial
    court and is reviewed by an appellate court de novo on the
    record for abuse of discretion. In re Guardianship of S.T.,
    
    300 Neb. 72
    , 
    912 N.W.2d 262
     (2018). In considering whether
    jurisdiction exists under the UCCJEA, a jurisdictional ques-
    tion that does not involve a factual dispute is determined

    by an appellate court as a matter of law, which requires an
    appellate court to reach a conclusion independent from the
    trial court. In re Guardianship of S.T., 
    supra.
    ANALYSIS
    Jurisdiction
    [3] Before reaching the legal issues presented for review, it
    is the duty of an appellate court to determine whether it has
    jurisdiction over the matter before it. Chief Indus. v. Great
    Northern Ins. Co., 
    259 Neb. 771
    , 
    612 N.W.2d 225
     (2000).
    This claim involves a request by Brian to modify a dissolu-
    tion decree entered by the district court in July 2018. Although
    the request to modify involves many issues that have not been
    resolved, Brian appeals from a partial summary judgment
    order which voided all portions of the court’s July 2018 decree
    involving the custody of Maleah on the basis that the court
    lacked subject matter jurisdiction to make custodial decisions
    due to jurisdictional power retained by a California court. Asia
    argues that because the partial summary judgment order does
    not constitute a final, appealable order, this court lacks juris-
    diction to hear this appeal.
    [4-6] The question of whether an order which does not
    finally resolve all issues may constitute a final order was
    recently addressed by the Nebraska Supreme Court in Simms v.
    Friel, 
    302 Neb. 1
    , 
    921 N.W.2d 369
     (2019). In Simms v. Friel,
    the Supreme Court held:
    For an appellate court to acquire jurisdiction of an appeal,
    there must be a final order or final judgment entered
    by the court from which the appeal is taken. Jennifer
    T. v. Lindsay P., 
    298 Neb. 800
    , 
    906 N.W.2d 49
     (2018).
    Because the temporary order did not dismiss the action
    or make a final determination on the merits, it was not a
    final judgment. See 
    id.
     The jurisdictional question before
    us is thus whether we are presented with a final order.
    Relevant here, among the three types of final orders
    which may be reviewed on appeal is an order that
    - 554 -
    Nebraska Court of Appeals Advance Sheets
    29 Nebraska Appellate Reports
    MANN v. MANN
    Cite as 
    29 Neb. App. 548
    affects a substantial right made during a special proceed-
    ing. See 
    Neb. Rev. Stat. § 25-1902
     (Reissue 2016). A
    “substantial right” is an essential legal right, not a mere
    technical right. See Steven S. v. Mary S., 
    277 Neb. 124
    ,
    
    760 N.W.2d 28
     (2009). A substantial right is affected if
    the order affects the subject matter of the litigation, such
    as diminishing a claim or defense that was available to
    an appellant prior to the order from which an appeal is
    taken. 
    Id.
     It is not enough that the right itself be substan-
    tial; the effect of the order on that right must also be sub-
    stantial. See Cano v. Walker, 
    297 Neb. 580
    , 
    901 N.W.2d 251
     (2017). Whether the effect of an order is substantial
    depends on whether it affects with finality the rights of
    the parties in the subject matter. 
    Id.
     Most fundamentally,
    an order affects a substantial right when the right would
    be significantly undermined or irrevocably lost by post-
    poning appellate review. Tilson v. Tilson, 
    299 Neb. 64
    ,
    
    907 N.W.2d 31
     (2018).
    Where visitation, custody, and the parent-child rela-
    tionship are involved, we have previously looked to juve-
    nile cases for guidance to determine whether the grant or
    denial of visitation and custody affects a substantial right.
    See Steven S. v. Mary S., supra. In doing so, we have said
    that “‘“[t]he question . . . whether a substantial right of
    a parent has been affected by an order in juvenile court
    litigation is dependent upon both the object of the order
    and the length of time over which the parent’s relation-
    ship with the juvenile may reasonably be expected to be
    disturbed.”’” Id. at 130, 
    760 N.W.2d at 33-34
    .
    
    302 Neb. at 4-5
    , 921 N.W.2d at 373.
    Here, the district court’s voiding of a prior custody deter-
    mination involving Maleah fits the definition of a substantial
    right. The court’s ruling, which previously bestowed certain
    custodial rights to Brian under the doctrine of in loco parentis
    was permanently voided due to the district court’s determi-
    nation that it lacked subject matter jurisdiction to enter the
    - 555 -
    Nebraska Court of Appeals Advance Sheets
    29 Nebraska Appellate Reports
    MANN v. MANN
    Cite as 
    29 Neb. App. 548
    prior order. Unlike a temporary order in a juvenile proceeding,
    the district court’s November 2019 order permanently dimin-
    ished Brian’s right to custody under the prior order, which
    right would be significantly undermined by postponing appel-
    late review. We hold that the court’s partial summary judgment
    order affects a substantial right of Brian.
    [7] Asia does not contest that the matter does not affect a
    substantial right. Instead, she argues that a summary judg-
    ment is not a special proceeding and that therefore, the court’s
    order does not qualify as a final order. But Asia misconstrues
    the meaning of a special proceeding. The request for a partial
    summary judgment is a procedural device available under the
    rules of civil procedure. The modification action itself is the
    proceeding. And the Nebraska Supreme Court has already held
    that child custody determinations are special proceedings for
    purposes of determining whether an order is a final, appealable
    order. See Steven S. v. Mary S., 
    277 Neb. 124
    , 
    760 N.W.2d 28
     (2009).
    Because we find that the district court’s November 2019
    partial summary judgment order, as clarified in its December
    order, affects a substantial right in a special proceeding, we
    find that this is a final, appealable order which conferred juris-
    diction on this court to review the legal issues presented for
    review in that order.
    Void Order
    Brian’s sole assignment of error is that the district court
    erred in finding it could vacate its prior custodial order govern-
    ing Maleah, which order was entered in the July 2018 dissolu-
    tion decree, because the court erroneously determined that it
    did not have subject matter jurisdiction to enter the order.
    Brian’s argument is based upon the treatment of subject
    matter jurisdiction among courts having concurrent inter-
    state jurisdiction as provided in the UCCJEA. He argues that
    although a California court originally obtained jurisdiction
    governing the custody determination of Maleah, that juris-
    diction did not deprive the Nebraska court of subject matter
    - 556 -
    Nebraska Court of Appeals Advance Sheets
    29 Nebraska Appellate Reports
    MANN v. MANN
    Cite as 
    29 Neb. App. 548
    jurisdiction to enter its July 2018 order. Accordingly, Brian
    argues that because the district court had subject matter juris-
    diction to enter the July 2018 dissolution decree, that decree
    was not void and the court erred in attempting to vacate por-
    tions of the July 2018 dissolution decree in the subsequent
    modification action filed in July 2019.
    [8,9] Before we address Brian’s specific jurisdictional argu-
    ment here, we first provide some background that is relevant to
    this determination.
    Jurisdiction over a child custody proceeding is gov-
    erned exclusively by the UCCJEA. Jurisdiction over cus-
    tody matters having interstate dimension must be deter-
    mined independently by application of the UCCJEA.
    The UCCJEA was enacted to serve the following pur-
    poses: (1) to avoid interstate jurisdictional competition
    and conflict in child custody matters, (2) to promote
    cooperation between courts of other states so that a cus-
    tody determination can be rendered in a state best suited
    to decide the case in the interest of the child, (3) to dis-
    courage the use of the interstate system for continuing
    custody controversies, (4) to deter child abductions, (5)
    to avoid relitigation of custody issues, and (6) to facilitate
    enforcement of custody orders.
    Carter v. Carter, 
    276 Neb. 840
    , 845, 
    758 N.W.2d 1
    , 6-7 (2008).
    Here, in 2010, the California court entered a custody order
    for Maleah, which order granted legal and physical custody to
    Asia with reasonable rights of visitation to Patrick, Maleah’s
    father. Neither party to this action contests that the California
    court first obtained jurisdiction to make a child custody deter-
    mination governing Maleah.
    
    Neb. Rev. Stat. § 43-1239
     (Reissue 2016) of the UCCJEA
    provides:
    (a) Except as otherwise provided in section 43-1241,
    a court of this state which has made a child custody
    determination consistent with section 43-1238 or 43-1240
    has exclusive, continuing jurisdiction over the determina-
    tion until:
    - 557 -
    Nebraska Court of Appeals Advance Sheets
    29 Nebraska Appellate Reports
    MANN v. MANN
    Cite as 
    29 Neb. App. 548
    (1) a court of this state determines that neither the
    child, nor the child and one parent, nor the child and a
    person acting as a parent have a significant connection
    with this state and that substantial evidence is no longer
    available in this state concerning the child’s care, protec-
    tion, training, and personal relationships; or
    (2) a court of this state or a court of another state deter-
    mines that the child, the child’s parents, and any person
    acting as a parent do not presently reside in this state.
    (b) A court of this state which has made a child custody
    determination and does not have exclusive, continuing
    jurisdiction under this section may modify that determina-
    tion only if it has jurisdiction to make an initial determi-
    nation under section 43-1238.
    California has a similar statute found at 
    Cal. Fam. Code § 3422
    (Deering 2020).
    Again, neither party disputes that the California court had
    exclusive continuing jurisdiction over this matter.
    
    Neb. Rev. Stat. § 43-1240
     (Reissue 2016) of the UCCJEA
    provides:
    Except as otherwise provided in section 43-1241, a
    court of this state may not modify a child custody deter-
    mination made by a court of another state unless a
    court of this state has jurisdiction to make an initial
    determination under subdivision (a)(1) or (a)(2) of sec-
    tion 43-1238 and:
    (1) the court of the other state determines it no ­longer
    has exclusive, continuing jurisdiction under section
    43-1239 or that a court of this state would be a more
    ­convenient forum under section 43-1244; or
    (2) a court of this state or a court of the other state
    determines that the child, the child’s parents, and any
    person acting as a parent do not presently reside in the
    other state.
    [10] Brian does not dispute that § 43-1240 would gov-
    ern any attempt by himself or Asia to modify the California
    - 558 -

    29 Neb. App. 548
    court’s decree, nor does Brian argue that the California court
    no longer has exclusive continuing jurisdiction as provided by
    statute. Brian simply argues that even though the California
    court had continuing exclusive jurisdiction, this did not deprive
    the Nebraska district court of subject matter jurisdiction. In
    support of that argument, Brian cites to Susan L. v. Steven L.,
    
    273 Neb. 24
    , 
    729 N.W.2d 35
     (2007), which establishes that
    states have “concurrent” jurisdiction over child custody deter-
    mination under the UCCJEA, and Charleen J. v. Blake O.,
    
    289 Neb. 454
    , 
    855 N.W.2d 587
     (2014), which held that, when
    courts have concurrent jurisdiction, their authority is governed
    by the doctrine of jurisdictional priority. Brian then cites to the
    Nebraska Supreme Court’s jurisdictional statement governing
    the doctrine of jurisdictional priority:
    Some confusion has developed from our failure to
    always distinguish the improper exercise of jurisdic-
    tion under judicial comity from a lack of subject matter
    jurisdiction. We have sometimes said, under the doctrine
    of jurisdictional priority, that a second court lacks “juris-
    diction.” We mean that a subsequent court that decides
    a case already pending in another court with concur-
    rent subject matter jurisdiction errs in the exercise of
    its jurisdiction. Jurisdictional priority is neither a matter
    of subject matter jurisdiction nor personal jurisdiction.
    The subsequent court does not lack judicial power over
    the general class or category to which the proceedings
    belong and the general subject involved in the action
    before the court.
    Charleen J. v. Blake O., 289 Neb. at 462-63, 855 N.W.2d
    at 595.
    Based on the doctrine of judicial priority, Brian argues
    that because the Nebraska district court had subject matter
    jurisdiction in rendering the July 2018 dissolution decree, the
    court simply erred in the exercise of subject matter jurisdic-
    tion over custody issues related to Maleah. Brian then argues
    that this made the July 2018 dissolution decree voidable, but
    - 559 -

    MANN v. MANN
    Cite as 
    29 Neb. App. 548
    not void. And Brian argues that because neither party appealed
    from the July 2018 decree, any attempt by a party to have
    the order voided in the subsequent modification proceedings
    constitutes a collateral attack on the original decree which the
    law does not allow. See Sanders v. Frakes, 
    295 Neb. 374

     (2016).
    Assuming without deciding that the Nebraska district court
    had subject matter jurisdiction when it entered the July 2018
    dissolution decree, it then vacated the decree during the
    course of the modification action filed in 2019. The Nebraska
    court, upon learning it should not have exercised jurisdiction
    on issues related to Maleah’s custody due to the California
    court’s continuing jurisdiction, most certainly had the power
    to vacate that portion of the decree if it was brought during
    the original dissolution action filed in 2018. See Charleen J. v.
    Blake O., supra (affirming district court’s order vacating prior
    rulings due to another court’s jurisdictional priority). But did
    the Nebraska district court retain the power to vacate its prior
    order through the modification action? We hold that it did.
    [11,12] As the Nebraska Supreme Court held in Charleen J.
    v. Blake O.:
    In custody matters, we speak of “‘continuing jurisdic-
    tion.’” In that sense, the action concerning custody of
    the child is not terminated, resolved, or disposed of until
    the age of majority. We have said that an application to
    modify a custody determination is not an independent
    proceeding, but is simply a proceeding supplementary or
    auxiliary to the original action in which certain matters
    were subject to modification.
    Other courts have more specifically held that a court
    which renders judgment for alimony, custody, or child
    support incident to an action for divorce or paternity
    retains the exclusive exercise of jurisdiction for purposes
    of modifying such a decree. In other words, where the
    first district court has issued a custody order, the issue
    of the child’s custody remains pending in that court for

    purposes of a jurisdictional priority analysis. If the parties
    in such circumstances wished to proceed on a motion to
    modify in another county, they would first request from
    the court that issued the original order a transfer of venue
    or otherwise gain the original court’s assent to another
    court’s exercise of jurisdiction.

    Because the district court retained jurisdiction over custody
    matters raised and decided in the 2018 decree, the subsequent
    modification action cannot be described as a collateral attack.
    See Sanders v. Frakes, 
    295 Neb. at 379-80
    , 888 N.W.2d at
    520 (holding “[a] collateral attack on a judgment is where the
    judgment is attacked in a way other than a proceeding in the
    original action to have it vacated, reversed, or modified, or
    a proceeding in equity to prevent its enforcement”). Having
    retained jurisdiction over the matter, the question becomes
    whether the district court retained the authority to vacate its
    prior order, albeit out of term.
    
    Neb. Rev. Stat. § 25-2001
    (4) (Reissue 2016) provides that
    “[a] district court may vacate or modify its own judgments or
    orders after the term at which such judgments or orders were
    made . . . for mistake, neglect, or omission of the clerk, or
    irregularity in obtaining a judgment or order.”
    [13-16] In Roemer v. Maly, 
    248 Neb. 741
    , 743-45, 
    539 N.W.2d 40
    , 43-44 (1995), the Nebraska Supreme Court explained:
    A litigant seeking vacation or modification of a judg-
    ment after term may take one of two routes: The litigant
    may proceed either under § 25-2001 or under the district
    court’s independent equity jurisdiction. Welch v. Welch,
    
    246 Neb. 435
    , 
    519 N.W.2d 262
     (1994). This court will
    reverse a decision on a motion to vacate or modify a
    judgment only if the litigant shows that the district court
    abused its discretion. Jarrett v. Eichler, 
    244 Neb. 310
    ,
    
    506 N.W.2d 682

    Under the auspice of § 25-2001(3), a district court
    may vacate or modify its own judgment after the term in
    which that judgment was rendered if the moving party
    can show “mistake, neglect, or omission of the clerk, or
    irregularity in obtaining a judgment or order.” . . .
    ....
    Roemer next attempts to trigger § 25-2001(3) by assert-
    ing that an irregularity occurred in obtaining the judgment
    or order. Her argument seems to be predicated on the
    notion that because a notice is sent for the purpose that it
    be received, that purpose is frustrated—and an “irregular-
    ity” occurs—when the notice is not received and cause is
    not shown.
    The operative definition of “irregularity” in our prec-
    edent, however, limits the term to “‘[t]he doing or not
    doing that, in the conduct of a suit at law, which, con-
    formably with the practice of the court, ought or ought
    not to be done. . . .’” (Emphasis omitted.) Haen v. Haen,
    
    210 Neb. 380
    , 382, 
    314 N.W.2d 276
    , 277 (1982). A judg-
    ment marred by irregularity is one rendered contrary to
    the course of law and practice of the court. Haen, supra.
    An example of irregularity under these circumstances
    would be dismissal for want of prosecution entered with-
    out any opportunity to show cause, not failure of counsel
    to take notice of opportunity given in accordance with
    court rules. The record reveals no deviation by the clerk
    from the standard practice of the district court of sending
    notice to counsel of record and publishing notice in The
    Daily Reporter.
    Here, the district court acknowledged that at the time it
    entered the 2018 dissolution decree, the court was unaware
    of the California order and that the California court retained
    exclusive, continuing jurisdiction over Maleah. Pursuant
    to § 43-1240 and California’s equivalent statute, 
    Cal. Fam. Code § 3423
     (Deering 2020), “a court of this state may not
    modify a child custody determination made by a court of
    - 562 -

    another state” under these circumstances. Although this may
    not deprive the court of subject matter jurisdiction, as the
    Nebraska Supreme Court held in Charleen J. v. Blake O., 
    289 Neb. 454
    , 463, 
    855 N.W.2d 587
    , 595 (2014), by unknowingly
    accepting jurisdiction under these circumstances, it “err[ed]
    in the exercise of its jurisdiction.” (Emphasis in original.)
    Because the district court erred in the exercise of jurisdiction
    and was statutorily precluded from doing so, we concluded
    this error fits squarely within the definition in § 25-2001(4)(a)
    of an “irregularity in obtaining a judgment or order.” Pursuant
    to § 25-2001(4)(a), the district court, which retained jurisdic-
    tion over the matter, was authorized to vacate that order once
    it was apprised of that irregularity out of term. See Roemer v.
    Maly, 
    248 Neb. 741
    , 
    539 N.W.2d 40
     (1995) (judgment marred
    by irregularity is one rendered contrary to course of law and
    practice of court).
    Because the district court retained the right to vacate its
    prior order and did not abuse its discretion in doing so, Brian’s
    argument fails that the court, in vacating that portion of the
    2018 dissolution decree governing the custody of Maleah,
    lacked the power to do so.
    CONCLUSION
    In sum, we determined that the district court’s November
    2019 partial summary judgment order, as clarified in its
    December order, affected a substantial right in a special pro-
    ceeding and constituted a final, appealable order which con-
    ferred jurisdiction on this court to review the legal issues
    presented for review. We then determined that the district court
    retained the right in a modification of a dissolution proceed-
    ing to vacate a prior order relating to the custody of the minor
    child whose custody had been the subject of a prior order by
    a California court, which court retained continuing exclusive
    jurisdiction over the minor child. Accordingly, we affirm the
    district court’s order of partial summary judgment.
    Affirmed.
