    COURT OF APPEAL, FOURTH APPELLATE DISTRICT

    STATE OF CALIFORNIA
    In re the Marriage of GABRIELA and               D063857
    CHRISTOPHER HAUGH.
    GABRIELA CASTRO,
    (Super. Ct. No. D490082)
    Respondent,
    v.
    CHRISTOPHER HAUGH,
    Respondent;
    SAN DIEGO COUNTY DEPARTMENT OF
    CHILD SUPPORT SERVICES,
    Appellant.
    APPEAL from an order of the Superior Court of San Diego County, Adam
    Wertheimer, Commissioner. Reversed and remanded with directions.
    Kamala D. Harris, Attorney General, Julie Weng-Gutierrez, Assistant Attorney
    General, Linda M. Gonzalez and Marina L. Soto, Deputy Attorneys General, for
    Appellant.
    No appearance for Respondents.
    The San Diego County Department of Child Support Services (Department), as
    intervenor, appeals the trial court's order granting the request by Christopher Haugh
    (Father) for modification of a child support order. Father sought to lower child support
    for the son he had with Gabriela Haugh, now known as Gabriela Castro (Mother). On
    appeal, Department contends the trial court acted in excess of its jurisdiction because
    Father, Mother, and their son resided outside of California at the time of the modification
    request and therefore, pursuant to Family Code1 section 4909, the court did not have
    continuing, exclusive jurisdiction to modify the original child support order. Section
    4909 is California's enactment of section 205 of the Uniform Interstate Family Support
    Act (UIFSA). We conclude the trial court acted in excess of its authority and therefore
    reverse the order.
    FACTUAL AND PROCEDURAL BACKGROUND
    In 2008, the trial court ordered Father to pay Mother $700.00 per month in child
    support for their son. In 2007, Mother moved with their son from California to Texas. In
    or about 2011, Father moved from California to Nevada.
    On January 14, 2013, Father filed a request to modify the amount of his child
    support payments based on his reduced income. Mother opposed his request for
    modification, arguing the matter should be heard in the state of their son's residence (i.e.,
    Texas) because none of the parties lived in California.
    1      All statutory references are to the Family Code unless otherwise specified.
    2
    At the hearing on Father's modification request, Father appeared telephonically
    and was represented by counsel, Mother appeared telephonically in propria persona, and
    Department appeared as an intervenor. Department's counsel stated the first issue for the
    court was whether the court had continuing, exclusive jurisdiction in the case. She
    argued that because Mother, Father, and their son no longer resided in California, the trial
    court did not have jurisdiction under section 4909, subdivision (a), to modify the original
    child support order. She suggested Father could have the original child support order
    registered in Texas and then seek its modification. However, the trial court, noting the
    original child support order was a California order, stated it "continues to have
    jurisdiction, until another state assumes jurisdiction. You don't leave a party without a
    forum." It further stated: "It's clear [that] California shouldn't continue to have it. But it
    does. That is -- [it] should be in someone else's jurisdiction. But someone needs to take
    that affirmative step, whether Mother, Father, or [Department]. [¶] I assume it's the
    Father, since he's the payor . . . ." The court then proceeded to hear arguments on the
    merits of Father's request for modification. Based on the evidence, the court issued an
    order (Order) modifying the original child support order, reducing Father's child support
    obligation to $508 per month, effective February 1, 2013. Department timely filed a
    notice of appeal challenging the Order.

    DISCUSSION
    I
    UIFSA and Section 4909
    This appeal involves the application of section 4909 (California's adoption of
    § 205 of the UIFSA) to the undisputed facts relevant to this appeal. We begin by
    reviewing the relevant provisions of section 4909, the UIFSA, and applicable regulations.
    "The Uniform Interstate Family Support Act (9 pt. [I]B West's U. Laws Ann. (1999) U.
    Interstate Fam. Support Act, § 101 et seq. (UIFSA)), which has been adopted by all [50]
    states, governs . . . the procedures for establishing, enforcing and modifying child support
    orders in cases in which more than one state is involved. The 1996 version of the UIFSA
    took effect in California on August 4, 1997. (See Fam. Code, § 4900 et seq.) Together
    with the Federal Full Faith and Credit for Child Support Orders Act (FFCCSOA) (28
    U.S.C. § 1738B), the UIFSA ensures that in every case only one state exercises
    jurisdiction over child support at any given time." (In re Marriage of Crosby & Grooms
    (2004) 
    116 Cal.App.4th 201
    , 206, fn. omitted.) 2
    2       California has also adopted the 2001 version of the UIFSA, but that version will
    not become operative until one of two events occurs: (1) the amendment by the United
    States Congress of title 42 United States Code section 666(f), to require or authorize, in
    connection with the approval of state plans for purposes of federal funding, the adoption
    of the 2001 version of the UIFSA; or (2) the approval, either generally or specifically
    regarding California, by the federal office of Child Support Enforcement or by the
    Secretary of Health and Human Services, of a waiver, exemption, finding, or other
    indicia of regulatory approval of the 2001 version of the UIFSA, in connection with the
    approval of state plans for purposes of federal funding. (Stats. 2002, ch. 349, § 47; see
    Historical and Statutory Notes, 29F pt. 2 West's Ann. Fam. Code (2013 ed.) preceding
    div. 9, pt. 5, ch. 6, at p. 6.) Based on Department's representations, we presume neither
    4
    The "cornerstone" of the UIFSA is the concept of "continuing, exclusive
    jurisdiction," codified in California as section 4909. (Stone v. Davis (2007) 
    148 Cal.App.4th 596
    , 600.) "UIFSA was designed to ensure that only one state at a time
    would have jurisdiction to make and modify a child support order. '[T]he central
    jurisdictional feature of UIFSA is the concept of continuing, exclusive jurisdiction.
    Under UIFSA, a court that makes a valid child support order retains exclusive jurisdiction
    to modify the order as long as the requirements for continuing, exclusive jurisdiction
    remain fulfilled. The court of another state may enforce a child support order registered
    in that state, but may not modify it unless the decree state has lost its continuing,
    exclusive jurisdiction.' " (Knabe v. Brister, supra, 154 Cal.App.4th at p. 1319.)
    Regarding "continuing, exclusive jurisdiction," section 4909 provides in pertinent
    part:
    "(a) A tribunal of this state issuing a support order consistent with
    the law of this state has continuing, exclusive jurisdiction over a
    child support order:
    "(1) As long as this state remains the residence of the obligor, the
    individual obligee, or the child for whose benefit the support order is
    issued; or
    of those events has yet to occur, thereby making the 1996 version of the UIFSA the
    operative version for purposes of this appeal. (See also Knabe v. Brister (2007) 
    154 Cal.App.4th 1316
    , 1319, fn. 2 ["California currently operates under the 1996 version of
    UIFSA . . . . [Citation.] California has adopted the 2001 version, but the Legislature
    conditioned its effectiveness on events that have yet to occur."].) In any event, to the
    extent the 2001 version of the UIFSA is operative, its provisions, including its drafters'
    comments, provide even greater support for our disposition of this appeal.
    5
    "(2) Until all of the parties who are individuals have filed written
    consents with the tribunal of this state for a tribunal of another state
    to modify the order and assume continuing, exclusive jurisdiction.
    "(b) A tribunal of this state issuing a child support order consistent
    with the law of this state may not exercise its continuing jurisdiction
    to modify the order if the order has been modified by a tribunal of
    another state pursuant to this chapter or a law substantially similar to
    this chapter. . . ." (Italics added.)
    Section 4909 is California's adoption of section 205 of the UIFSA. The drafter's
    comment to the 1996 version of section 205 of the UIFSA states in pertinent part:
    "This section is perhaps the most crucial provision in UIFSA. . . .
    [T]he issuing tribunal retains continuing, exclusive jurisdiction over
    a child support order, except in very narrowly defined
    circumstances. As long as one of the individual parties or the child
    continues to reside in the issuing state, and as long as the parties do
    not agree to the contrary, the issuing tribunal has continuing,
    exclusive jurisdiction over its order--which in practical terms means
    that it may modify its order. . . .
    "The other side of the coin follows logically. Just as Subsection
    (a)(1) defines the retention of continuing, exclusive jurisdiction, by
    clear implication the subsection also defines how jurisdiction to
    modify may be lost. That is, if all the relevant persons--the obligor,
    the individual obligee, and the child--have permanently left the
    issuing state, the issuing state no longer has an appropriate nexus
    with the parties or child to justify exercise of jurisdiction to modify.
    Further, the issuing tribunal has no current information about the
    factual circumstances of anyone involved, and the taxpayers of that
    state have no reason to expend public funds on the process. . . .
    "According to the logical implication of Subsection (a)(2), the
    issuing state may also lose its continuing, exclusive jurisdiction to
    modify if the parties consent in writing for another state to assume
    jurisdiction to modify (even though one of the parties or the child
    continues to reside in the issuing state). . . ." (9 pt. IB West's U.
    6
    Laws. Ann., supra, U. Interstate Fam. Support Act, comment to
    § 205, pp. 340-341, italics added.)3
    II
    Continuing, Exclusive Jurisdiction in This Case
    Department contends the trial court acted in excess of its jurisdiction by issuing
    the Order modifying the original 2008 child support order. It argues that because Father,
    Mother, and their son no longer resided in California at the time of Father's modification
    request and the court's issuance of the Order, the court did not have continuing, exclusive
    jurisdiction under section 4909 and therefore could not modify the original child support
    order. Father has not filed a respondent's brief opposing Department's position. We
    decide this appeal based on the appellant's opening brief, the record on appeal, and our
    independent research regarding applicable law.
    Based on our review of section 4909, the UIFSA and comments thereto, other
    statutes and regulations, and relevant case law, we conclude the trial court acted in excess
    of its authority under section 4909 by modifying the original child support order. The
    court did not have continuing, exclusive jurisdiction to modify the original child support
    order after the individual parties and their child moved to other states and did not consent
    in writing to California's continuing jurisdiction or authority over the case.
    Section 4909, subdivision (a), provides that a California court "has continuing,
    exclusive jurisdiction over a child support order: [¶] (1) As long as this state remains the
    3      All further references to section 205 of the UIFSA are to its 1996 version.
    7
    residence of the obligor, the individual obligee, or the child for whose benefit the support
    order is issued; or [¶] (2) Until all of the parties who are individuals have filed written
    consents with the tribunal of this state for a tribunal of another state to modify the order
    and assume continuing, exclusive jurisdiction." (§ 4909, subd. (a), italics added.)
    The proper interpretation of section 4909 is a question of law, which we conduct
    de novo. (Stone v. Davis, supra, 148 Cal.App.4th at p. 600; People ex rel. Lockyer v.
    Shamrock Foods Co. (2000) 
    24 Cal.4th 415
    , 432.) The basic rules for statutory
    construction are established. " 'As in any case involving statutory interpretation, our
    fundamental task here is to determine the Legislature's intent so as to effectuate the law's
    purpose.' [Citation.] 'We begin with the plain language of the statute, affording the
    words of the provision their ordinary and usual meaning and viewing them in their
    statutory context, because the language employed in the Legislature's enactment
    generally is the most reliable indicator of legislative intent.' [Citations.] The plain
    meaning controls if there is no ambiguity in the statutory language. [Citation.] If,
    however, 'the statutory language may reasonably be given more than one interpretation,
    " ' "courts may consider various extrinsic aids, including the purpose of the statute, the
    evils to be remedied, the legislative history, public policy, and the statutory scheme
    encompassing the statute." ' " ' " (People v. Cornett (2012) 
    53 Cal.4th 1261
    , 1265.)
    Applying the above rules for statutory construction, we first look to the language
    of section 4909 to determine its meaning. Because section 4909 is written (as is § 205 of
    the UIFSA) using the disjunctive "or," there appear to be two alternative situations in
    8
    which a California court will no longer have continuing, exclusive jurisdiction to modify
    an original child support order. First, by negative implication, a California court will not
    have jurisdiction if all of the individual parties and the child reside in other states.
    (§ 4909, subd. (a)(1).) Second, the court will not have jurisdiction if at least one
    individual party or the child resides in California, but all of the individual parties (e.g.,
    mother and father) file a written consent with the California court agreeing that a court of
    another state will have continuing, exclusive jurisdiction to modify the original child
    support order. (§ 4909, subd. (a)(2).) Based on our reading of section 4909, the above
    interpretation appears to be the most logical interpretation of its language. Nevertheless,
    to the extent that statutory language is ambiguous, we conclude the legislative intent
    underlying section 4909, including the intent that its provisions be consistent with the
    UIFSA and, presumably, with other states' interpretations, supports our interpretation that
    a California court does not have continuing, exclusive jurisdiction within the meaning of
    section 4909 if all the individual parties and the child reside in other states, and all of the
    individual parties have not consented in writing to a California court assuming
    continuing, exclusive jurisdiction. Because the record in this case does not show the
    existence of any written consent, we focus on the effect of the parties' not residing in
    California on a California court's continuing, exclusive jurisdiction to modify a child
    support order.
    Section 4909 represents California's adoption of the 1996 version of section 205 of
    the UIFSA. The drafters' comment to that UIFSA section provides evidence of the
    9
    legislative intent underlying section 4909, stating: "[T]he issuing tribunal retains
    continuing, exclusive jurisdiction over a child support order, except in very narrowly
    defined circumstances. As long as one of the individual parties or the child continues to
    reside in the issuing state, and as long as the parties do not agree to the contrary, the
    issuing tribunal has continuing, exclusive jurisdiction over its order--which in practical
    terms means that it may modify its order." (9 pt. IB West's U. Laws. Ann., supra, U.
    Interstate Fam. Support Act, comment to § 205, p. 340, italics added.) It further states:
    "[B]y clear implication [subsection (a)(1)] also defines how jurisdiction to modify may be
    lost. That is, if all the relevant persons--the obligor, the individual obligee, and the
    child--have permanently left the issuing state, the issuing state no longer has an
    appropriate nexus with the parties or child to justify exercise of jurisdiction to modify."
    (9 pt. IB West's U. Laws. Ann., supra, U. Interstate Fam. Support Act, comment to § 205,
    p. 340, italics added.) The comment further notes: "[T]he issuing state may also lose its
    continuing, exclusive jurisdiction to modify if the parties consent in writing for another
    state to assume jurisdiction to modify (even though one of the parties or the child
    continues to reside in the issuing state). . . ." (9 pt. IB West's U. Laws. Ann., supra, U.
    Interstate Fam. Support Act, comment to § 205, p. 341.) Accordingly, the drafters of the
    UIFSA intended section 205 to provide that "continuing, exclusive jurisdiction" would
    necessarily be lost by the state issuing the original child support order when all of the
    relevant persons (i.e., obligor, obligee, and child) have moved out of the issuing state
    (e.g., California) and reside in other states.
    10
    Additional evidence of the UIFSA drafters' interpretation of "continuing, exclusive
    jurisdiction" is shown in their prefatory notes to the UIFSA:
    "Except for narrowly defined fact circumstances, under UIFSA the
    only tribunal that can modify a support order is the one having
    continuing, exclusive jurisdiction over the order. But, if the parties
    no longer reside in the issuing state, or if they agree in writing that
    another tribunal may assume modification jurisdiction, a tribunal
    with personal jurisdiction over the parties, has jurisdiction to modify
    [citations]. Except for modification by agreement or when the
    parties have all moved to the same new state, the party petitioning
    for modification must submit himself or herself to the forum state
    where the respondent resides." (9 pt. IB West's U. Laws. Ann.,
    supra, U. Interstate Fam. Support Act, prefatory note, pt. IID2, pp.
    288-289, italics added.)
    We conclude the Legislature, by adopting the 1996 version of section 205 of the
    UIFSA, intended that section 4909's language would be interpreted in the same manner
    as the UIFSA drafters intended the language of section 205 of the UIFSA to be
    interpreted. Therefore, the UIFSA drafters' comments support our interpretation of
    section 4909.
    The Federal Full Faith and Credit for Child Support Orders Act (FFCCSOA) (28
    U.S.C., § 1738B) also supports our interpretation of section 4909 (as well as the drafters'
    interpretation of § 205 of the UIFSA). To provide for the recognition and enforcement of
    other states' child support orders, Congress enacted the FFCCSOA requiring that states
    give full faith and credit to those child support orders issued by state courts that had
    continuing, exclusive jurisdiction over child support at the time. (28 U.S.C. § 1738B(a),
    (f), & (g).) That law provides that a state court shall not modify a child support order
    made by a court of another state unless it complies with the law's requirements. (28
    11
    U.S.C. § 1738B(a).) It provides that a court may modify a child support order of another
    state's court if that court has jurisdiction pursuant to 28 U.S.C. § 1738B(i) and "the court
    of the other State no longer has continuing, exclusive jurisdiction of the child support
    order because that State no longer is the child's State or the residence of any individual
    contestant; or [¶] . . . each individual contestant has filed written consent with the State of
    continuing, exclusive jurisdiction for a court of another State to modify the order and
    assume continuing, exclusive jurisdiction over the order." (28 U.S.C. § 1738B(e), italics
    added.) That law further provides: "If there is no individual contestant or child residing
    in the issuing State, the party or support enforcement agency seeking to modify, or to
    modify and enforce, a child support order issued in another State shall register that order
    in a State with jurisdiction over the nonmovant for the purpose of modification." (28
    U.S.C. § 1738B(i).) Those provisions of the FFCCSOA show Congress intended full
    faith and credit be given only to modifications of child support orders of state courts with
    continuing, exclusive jurisdiction over the case. Furthermore, Congress intended that a
    state court would not have such continuing, exclusive jurisdiction after the individual
    contestants and the child are no longer residents of that state. (28 U.S.C. § 1738B(e).)
    Therefore, the FFCCSOA supports our interpretation of "continuing, exclusive
    jurisdiction" as used in section 4909, subdivision (a).
    The California Department of Social Services has adopted a regulation informing
    local child support agencies, the Department in this case, of its interpretation of
    "continuing, exclusive jurisdiction" under section 4909, stating:
    12
    "(a) Except as specified in subsection (b), only the issuing state
    shall have continuing, exclusive jurisdiction to modify a support
    order.
    "(b) In determining whether it believes California or another state
    has continuing, exclusive jurisdiction to modify a support order, the
    local child support agency shall apply the following rules:
    "(1) Only one state shall have continuing, exclusive jurisdiction to
    modify a support order at any given time.
    "(2) If the child, the obligee who is an individual, or the obligor
    resides in the state that issued the controlling order, that state has
    continuing, exclusive jurisdiction to modify.
    "(3) Once a state has continuing, exclusive jurisdiction, it shall
    retain jurisdiction as long as any one of the parties or children in
    the case still resides in the state, unless the parties file a written
    consent in the issuing tribunal allowing another state, with personal
    jurisdiction over any of the parties, to assume continuing, exclusive
    jurisdiction to modify the order." (Cal. Code Regs., tit. 22,
    § 117300, italics added.)
    California's administrative regulations regarding section 4909 are consistent with the
    UIFSA drafters' interpretation of "continuing, exclusive jurisdiction" under section 205 of
    the UIFSA. We give strong deference to that agency's interpretation of section 4909, as
    the agency primarily charged with overseeing child support issues.
    Furthermore, as many courts have observed, almost every state court that has
    addressed the issue of "continuing, exclusive jurisdiction" under the UIFSA and/or its
    state's statutory version thereof has interpreted that phrase consistent with our
    interpretation of section 4909. For example, in Lunceford v. Lunceford (Mo.App. 2006)
    
    204 S.W.3d 699
    , the court stated:
    13
    "Virtually every jurisdiction that has addressed this issue has
    concluded that the issuing tribunal loses subject matter jurisdiction
    when all of the parties to the child support action have moved
    outside the state. See Knowlton v. Knowlton, 
    2005 OK CIV APP 22

    UIFSA to modify child support after both parties had moved out of
    state); LeTellier v. LeTellier, 
    40 S.W.3d 490
    , 493-94 (Tenn. 2001)
    (UIFSA does not confer subject matter jurisdiction upon the
    Tennessee court to hear mother's petition to modify the District of
    Columbia's support order); In re B.O.G., 
    48 S.W.3d 312
    , 318,
    (Tex.App. 2001) (Texas court no longer had jurisdiction to modify
    the support order under UIFSA because the parties no longer resided
    in Texas)." (Lunceford v. Lunceford, 
    supra, at p. 704
    , italics added;
    see also State ex rel. Brantingham v. Grate (Mo.App. 2006) 
    205 S.W.3d 317
    , 321.)
    Under Missouri's statutory version of the UIFSA, Lunceford concluded: "Missouri loses
    its continuing, exclusive jurisdiction to modify a Missouri child support order when
    neither the obligor, obligee, nor child is a resident of Missouri." (Lunceford, 
    supra,
     204
    S.W.3d at p. 705, italics added.) Nevertheless, an original Missouri child support order
    remains in effect for enforcement in that and other states until modified by another state
    with continuing, exclusive jurisdiction. (Id. at pp. 705, 707.) In the circumstances of that
    case, Lunceford held "the Missouri [trial] court did not have subject matter jurisdiction to
    hear Mother's petition to modify child support" (id. at p. 705) because at the time of her
    14
    petition Mother, Father, and, presumably, their child were all residents of other states
    (i.e., New Jersey and Tennessee). (Id. at p. 701.)
    Other courts have reached similar conclusions, finding their state courts lost
    jurisdiction or authority to modify child support orders after the mother, father, and child
    moved from their states. (See, e.g., Zaabel v. Konetski (Ill. 2004) 
    807 N.E.2d 372
    , 376;

    In Stone v. Davis, the Third District Court of Appeal interpreted section 4909,
    stating: "The statutory language is unambiguous and clear. A California court retains
    continuing, exclusive jurisdiction to modify a child support order it lawfully issued so
    long as one of the parties to the order continues to reside in the state, unless all of the
    parties to the order file with the California court a writing consenting to jurisdiction in
    another state, or another state court modified the order as allowed under the UIFSA."
    (Stone v. Davis, supra, 148 Cal.App.4th at p. 601, italics added.) In Stone, the court
    concluded the California trial court retained continuing, exclusive jurisdiction to modify
    its original child support order because the father still resided in California and there was
    no written consent of all the parties to jurisdiction in another state. (Id. at pp. 602-603;
    see also Spicer v. Spicer (La.Ct.App. 2011) 
    62 So.3d 798
    , 802 ["the Illinois court lacked
    subject matter jurisdiction to modify the child support order, because Louisiana retained
    the continuing, exclusive jurisdiction over the child support order under the UIFSA"
    because the father continued to reside in Louisiana].) Although Stone is factually
    inapposite to this case, its reasoning is consistent with our interpretation of section 4909.
    Our research located only one decision in another state that holds contrary to our
    interpretation of section 4909. In Wareham v. Wareham (Minn.App. 2010) 
    791 N.W.2d 562
    , a Minnesota appellate court interpreted a Minnesota statute with language similar to
    our section 4909, subdivision (a), as giving its state court continuing, exclusive
    jurisdiction even though the parties and their children did not currently reside in
    Minnesota. (Id. at p. 565-566.) Wareham stated:
    16
    "[B]ased on a plain-language reading of [the Minnesota statute], we
    conclude that the statute sets forth two distinct circumstances under
    which a Minnesota tribunal retains continuing, exclusive jurisdiction
    over its previously issued child-support order: where at least one of
    the parties or the covered children remains a Minnesota resident
    (subsection (a)(1)), or where at least one of the parties has not filed a
    written consent for a different state's tribunal to assume continuing,
    exclusive jurisdiction (subsection (a)(2))." (Wareham, supra, 791
    N.W.2d at p. 565.)
    The court found the first subsection did not apply because none of the parties or children
    resided in Minnesota. (Ibid.) However, it found the second subsection applied because
    there was no evidence the parties had filed any written consent with the Minnesota court
    transferring continuing, exclusive jurisdiction to another state. (Id. at pp. 565-566.)
    Therefore, Wareham concluded the Minnesota courts retained jurisdiction to modify its
    original child support order. (Id. at pp. 565-567.) However, we are unpersuaded by
    Wareham's reasoning and reject its "plain-language" interpretation of continuing,
    exclusive jurisdiction under the UIFSA. Based on our review of section 4909, section
    205 of the UIFSA and its drafters' comments, and overwhelming case law consistent with
    our interpretation, we believe Wareham stands alone as an exceptional viewpoint
    inconsistent with the underlying intent of the UIFSA (and FFCCSOA) that states have
    uniform laws regarding enforcement and modification of child support orders.
    Although many cases from other states cited above appear to equate a court's
    continuing, exclusive jurisdiction under the UIFSA with its subject matter jurisdiction to
    modify a child support order, we believe, at least in California, a trial court may have
    subject matter jurisdiction to modify a child support order even though it does not have
    17
    continuing, exclusive jurisdiction under section 4909 (or § 205 of the UIFSA). As
    Department notes, trial courts have original jurisdiction over all causes not otherwise
    conferred by the California Constitution. (Cal. Const., art. VI, § 10.) Because the
    California Constitution does not confer original jurisdiction over child support
    proceedings to any other court, trial courts have original jurisdiction over those
    proceedings. Furthermore, section 200 provides: "The superior court has jurisdiction in
    proceedings under this [Family Code]." Section 2010 also provides that in a proceeding
    for dissolution of marriage, the court has jurisdiction to make orders regarding the
    support of children. We conclude the trial court in this case had original jurisdiction, or
    subject matter jurisdiction, over the type of case involved in this matter (i.e., modification
    of a child support order). However, the existence of subject matter jurisdiction does not
    mean the court had the power to act "in excess of its jurisdiction," or, more accurately, in
    excess of its authority under section 4909, by issuing its order modifying the original
    child support order. (See, generally, Abelleira v. District Court of Appeal (1941) 
    17 Cal.2d 280
    , 287-291; cf. In re Marriage of Schneider & Almgren (Wash. 2011) 
    268 P.3d 215
    , 218-219 [although Washington trial court had subject matter jurisdiction to entertain
    child support controversies, court's lack of "continuing, exclusive jurisdiction" under
    Washington statute deprived it of the authority to issue an order modifying a child
    support order].)
    Based on the record on appeal in this case, we conclude the trial court did not have
    continuing, exclusive jurisdiction under section 4909 to modify the original child support
    18
    order. Father, Mother, and their son all resided outside of California at the time of
    Father's request to modify the child support order. Furthermore, there is no evidence
    showing Father or Mother filed a written consent in any court agreeing that the trial court
    would have continuing, exclusive jurisdiction over this matter. Therefore, the trial court
    erred by acting in excess of its authority under section 4909 by issuing the Order
    modifying the original child support order.
    DISPOSITION
    The Order is reversed and the matter is remanded with directions that the trial
    court vacate the Order granting Father's request to modify the original child support order
    and issue a new order denying that request.
