    JUSTICE PETERSEN, opinion of the Court:
    INTRODUCTION
    ¶1 Adam Mackley conceived a child with Adrienne Openshaw
    (Mother) while she was married to Colton Barney (Husband). Before
    the child’s birth, Mackley filed a paternity petition in the district
    court. Genetic testing, conducted after the child’s birth, established
    that the child was Mackley’s biological daughter. Husband later
    signed a voluntary denial of paternity, renouncing his paternity of
    the child. Despite this, Mother subsequently moved to dismiss
    Mackley’s petition, arguing that he lacked standing under the Utah
    Uniform Parentage Act (UUPA) to challenge Husband’s presumed
    paternity. Husband simultaneously commenced a separate action,
    petitioning the district court to declare him to be the child’s legal
    father. After extensive litigation in both cases, the district court
    permitted Husband to rescind the denial on the basis of mutual and
    unilateral mistake of fact. The court later granted Husband’s petition
    for declaratory judgment, which ultimately resulted in the dismissal
    of Mackley’s petition.
    ¶2 We are asked to determine, among other issues, whether the
    district court erred (1) in allowing rescission of the denial and (2) in
    holding that Mackley lacked standing to challenge Husband’s
    presumed paternity of the child. 2
    _____________________________________________________________
    2 Alternatively, Mackley contends that an interpretation of the
    UUPA denying him standing violates his constitutional rights to due
    process and equal protection. These same or similar arguments were
    raised in several companion cases that we also issue today. See Castro
    v. Lemus, 
    2019 UT 71

    , ¶ 19, --- P.3d ---; Olguin v. Anderton, 
    2019 UT 73
    , ¶ 18, --- P.3d ---.
    In Castro, we hold that the UUPA grants standing to alleged fathers
    to rebut the presumption of paternity.

                            Opinion of the Court
    ¶3 We conclude that Husband should not have been permitted
    to rescind the denial because any mistake went to the legal
    consequences of signing the document, not the facts forming the
    basis of it. The issue of Mackley’s standing is therefore moot. We
    reverse and remand.
    BACKGROUND
    ¶4 Mother and Husband married in August 2010. In early 2011,
    Mother had a sexual relationship with Mackley and became
    pregnant. Before learning of the pregnancy, Mother told Husband
    about her relationship with Mackley and the couple separated.
    Although Mother moved out of the marital home, the couple
    remained married. When Mother subsequently discovered that she
    was pregnant, she and Husband knew there was a possibility that
    Mackley was the child’s biological father. Despite this, the couple
    reconciled and worked to mend the marriage.
    ¶5 After learning of the pregnancy, Mackley began paying
    prenatal child support to Mother. And he filed a paternity petition in
    district court before the child was born. Mackley did not name or
    serve Husband as a party in that case.
    ¶6 In her answer, Mother asked the district court to dismiss
    Mackley’s petition, stating that she was “not sure who the father is
    and [did] not remember telling [Mackley] that [the child] was his.”
    Mother then asked the court to allow her and Husband to start their
    family, declaring that Husband “kn[ew] the whole situation and
    want[ed] to take full responsibility of the child regardless of DNA.”
    But she noted that Mackley could take the legal steps to get a
    paternity test if he wanted and that they would “go from there” if he
    elected to do so.
    ¶7 The child was born in October 2011. Although present at the
    birth, Husband was not listed on the child’s birth certificate.
    ¶8 After the child was born, Mackley requested that a paternity
    test be conducted. Mother submitted herself and the child to genetic
    testing. The test results established a 99.99 percent probability that
    the child is Mackley’s biological daughter.
    ¶9 Soon after, Mother and Mackley stipulated to temporary
    orders addressing, among other things, custody, parent-time, and
    standing to alleged fathers, we need not address Mackley’s
    constitutional challenges to a statutory interpretation that does not.
    3
    MACKLEY v. OPENSHAW
    Opinion of the Court
    child support. Mackley began to exercise parent-time in December
    2011. But increasing conflicts between Mother and Mackley over
    parent-time and the child’s medical care soon strained the
    relationship.
    ¶10 As part of the original stipulated temporary orders, Mother
    had agreed to add Mackley as the father on the child’s birth
    certificate. After some delay, Mackley repeatedly threatened to
    initiate court proceedings against her if she did not comply with the
    order. Mother eventually agreed to complete the necessary
    paperwork. Mackley completed and signed the applicable portion of
    a Voluntary Declaration of Paternity (declaration). 3 See UTAH CODE
    § 78B-15-302. He gave it to Mother, who took it with her to the Utah
    County Health Department. Husband accompanied Mother to
    provide emotional support.
    ¶11 At the health department, Mother signed the relevant
    portion of the declaration, in which she affirmed that “[Mackley] is
    the biological father of th[e] child” and that she was voluntarily
    _____________________________________________________________
    3  The UUPA provides that “The mother of a child and a man
    claiming to be the genetic father of the child may sign a declaration
    of paternity to establish the paternity of the child.” UTAH CODE
    § 78B-15-302(1). A man who establishes his paternity in this manner
    is called a “declarant father.” § 78B-15-102(8). The declaration of
    paternity must be signed, or otherwise authenticated, by both the
    mother and the declarant father. 
    Id. § 78B-15-302(1)(b).
    And if the
    child has a presumed father, as here, the presumed father must sign,
    or otherwise authenticate, a denial of paternity in order for the
    declaration of paternity to be valid. 
    Id. §§ 78B-15-302(3)(a),
    -303, -304.
    When both are required, a declaration of paternity and a denial of
    paternity must be contained in a single document, and neither is
    valid until both are signed and filed according to statute. 
    Id. § 78B-15-304(1).
    Once filed, a valid declaration of paternity “is
    equivalent to a legal finding of paternity of a child and confers upon
    the declarant father all of the rights and duties of a parent.” 
    Id. § 78B-15-305(1).
    The declaration of paternity then becomes an
    amendment to the child’s original birth certificate. See 
    id. § 78B-15-302(7).
        Here, there are some inconsistencies in the record regarding
    when the parties signed the declaration and denial. However, it is
    clear that Mother, Husband, and Mackley each signed the sections of
    the form relevant to him or her as prescribed by law.
    4
    Cite as: 
    2019 UT 74
                             Opinion of the Court
    providing the information “to formally declare the paternity of their
    child without obtaining a court order.” In addition, Mother affirmed
    that she “ha[d] been provided verbal and written notice of the legal
    consequences of and the alternatives to signing [the declaration].”
    ¶12 When an employee of the health department discovered
    that Husband was married to Mother, he was asked to sign a portion
    of the form. Husband had been unaware that he would be asked to
    sign any documents, but he complied. He signed a section of the
    form labeled in all capital letters: “DENIAL OF PATERNITY BY
    PRESUMED FATHER.” 4 In doing so, Husband affirmed, under
    penalty of perjury, “I am recognized as the ‘presumed father’[5]
    under Utah Law; however . . . I am NOT THE BIOLOGICAL
    FATHER OF THE CHILD ON PAGE ONE OF THIS
    DOCUMENT.” (Emphasis in original.) Like Mother, Husband also
    affirmed that he had “been provided verbal and written notice of the
    legal consequences of and the alternatives to signing this form.”
    Mackley was not informed that Mother had signed the declaration or
    that Husband had signed the denial.
    ¶13 Several months later at a pretrial hearing, the district court
    questioned why Mackley had not joined Husband in the case. Citing
    court of appeals’ precedent, the district court reasoned that
    Husband, the child’s presumed father, was likely an indispensable
    party. The court then decided to continue the hearing to allow time
    for the parties to investigate that issue.
    _____________________________________________________________
    4 The form the parties signed cites to an obsolete section of the
    Utah Code. Utah Code section 78-45g-204 was renumbered as
    section 78B-15-204 in 2008. The parties signed the form in 2012, but
    the form still listed the old section number.
    5 The denial includes a definition of “presumed father.” It states
    that a man is presumed to be the father of a child if:
    (a) he and the mother of the child are married to each
    other and the child is born during the marriage;
    (b) he and the mother of the child were married to each
    other and the child is born within 300 days after the
    marriage is terminated by death, annulment,
    declaration of invalidity, or divorce or after a decree
    of separation; [or]
    (c) after the birth of the child, he and the mother of the
    child married each other.
    5
    MACKLEY v. OPENSHAW
    Opinion of the Court
    ¶14 Mother subsequently moved to dismiss Mackley’s
    paternity petition, arguing that he lacked standing to challenge the
    child’s paternity under the UUPA 6 and that he had failed to join an
    indispensable party, Husband, the child’s presumed father. In the
    alternative, Mother asked the district court to determine that
    Mackley lacked standing to assert his paternity of the child under the
    common-law test adopted in In re J.W.F. (Schoolcraft), 
    799 P.2d 710
    (Utah 1990).
    ¶15 That same week, Husband petitioned for declaratory
    judgment in a separate case, asking the district court to declare that
    he is the child’s legal father and that Mackley therefore has no
    parental rights. In addition, Husband requested that the district
    court order his name to be substituted for Mackley’s on the child’s
    birth certificate, which would require Mackley to withdraw the
    declaration. 7 Husband, Mother, and Mackley are all parties to
    Husband’s case. Neither Mother’s motion to dismiss nor Husband’s
    petition for declaratory judgment mentioned that she had signed the
    declaration or that Husband had signed the denial.
    ¶16 The district court held a hearing for both cases. Because
    Husband had never been joined as a party to Mackley’s case, the
    court stayed Mackley’s paternity petition, pending resolution of
    Husband’s petition for declaratory relief (the case to which Mother,
    Husband, and Mackley were all parties). The court then orally
    declared that Husband, as the presumed father, was the child’s legal
    father and stated that its ruling would have res judicata effect on
    Mackley’s case.
    _____________________________________________________________
    6 At the time Mother moved to dismiss Mackley’s petition for lack
    of standing, the court of appeals had yet to issue its decision in R.P.
    v. K.S.W., 
    2014 UT App 38
    , 
    320 P.3d 1084
    (interpreting the UUPA to
    deny standing to alleged fathers when the child is born during a
    marriage and has a presumed father). Mother acknowledged that her
    interpretation of the UUPA was an issue of first impression but
    argued in favor of construing the statute to deny standing based on
    the policy considerations outlined in In re J.W.F. (Schoolcraft), 
    799 P.2d 710
    (Utah 1990).
    7 See UTAH CODE § 78B-15-308(5) (“At the conclusion of a
    proceeding to rescind or challenge a declaration of paternity or
    denial of paternity, the tribunal shall order the Office of Vital
    Records to amend the birth record of the child, if appropriate.”).

                             Opinion of the Court
    ¶17 After that hearing, Mackley discovered, for the first time,
    that Husband had signed the denial, which had the legal effect of
    denying Husband’s presumed paternity of the child. Based on this
    discovery, Mackley moved the district court for relief from judgment
    under rule 60(b) of the Utah Rules of Civil Procedure, arguing,
    among other things, that the denial constituted newly discovered
    evidence.
    ¶18 Without addressing Mackley’s rule 60(b) motion, the
    district court entered findings of fact, conclusions of law, and an
    order of declaratory judgment in Husband’s case. The order
    recognized Husband as the child’s legal father, determined that
    Mackley had no parental rights, and ordered Husband’s name to be
    substituted for Mackley’s on the child’s birth certificate and other
    legal documents.
    ¶19 The district court subsequently dismissed Mackley’s
    paternity petition. In doing so, the court struck the temporary orders,
    determined that Mackley lacked standing to file a paternity petition,
    and concluded that Husband was a necessary party who the court
    had determined was the child’s legal father.
    ¶20 Mackley appealed the district court’s rulings. The court of
    appeals then ordered the district court to hear and rule on Mackley’s
    rule 60(b) motion. After conducting a hearing, the district court
    granted Mackley’s motion for relief from judgment, ruling that the
    denial constituted newly discovered evidence. The court thus
    vacated both its order granting declaratory judgment in favor of
    Husband and its dismissal of Mackley’s paternity petition.
    ¶21 Several days before the district court issued its written
    order, Husband moved to rescind the denial. He argued that it
    should be rescinded based on material mistakes of fact and duress.
    After an evidentiary hearing, the district court granted Husband’s
    motion to rescind on the basis of mutual and unilateral mistake of
    fact. In particular, the court found that none of the parties were
    aware that Husband would be required to sign the denial and all
    three parties believed “the purpose of signing the form was to add
    [Mackley] to the birth certificate” and that “[n]one of the parties
    anticipated that signing the form would legally terminate
    [Husband’s] parental rights as the presumed father.” In support, the
    district court noted that the form does not indicate that by signing it,
    the presumed father is terminating his rights to the child.
    ¶22 Mother and Husband then moved the district court to
    reinstate its order for declaratory judgment in Husband’s case and
    7
    MACKLEY v. OPENSHAW
    Opinion of the Court
    its order of dismissal in Mackley’s case. The court granted the
    motions.
    ¶23 Mackley filed two notices of appeal with the court of
    appeals. He first appealed the district court’s December 21, 2016
    order of dismissal entered in his case. He then appealed two orders
    entered in Husband’s case: the district court’s March 15, 2016 order
    rescinding the denial and its October 22, 2016 order reinstating
    declaratory judgment. On its own motion, the court of appeals
    consolidated the cases. That court later certified the consolidated
    case to us to resolve unsettled questions of constitutional law.
    ¶24 We exercise jurisdiction pursuant to Utah Code section
    78A-3-102(3)(b).

    .
    ANALYSIS
    I.     MOTION TO STRIKE
    ¶26 Before addressing the merits of Mackley’s arguments, we
    must resolve a motion to strike portions of Mackley’s replacement
    brief filed by Husband and joined by Mother. In support, Husband
    and Mother note that in his opening brief to the court of appeals,
    Mackley did not include Husband on the caption or service list.
    When Mother’s attorney asked why Husband’s attorney had not
    been served a copy of the brief, Mackley responded by emailing one
    to him. Mackley then moved to amend the caption page and
    certificate of service, which the court of appeals granted. Husband
    requested that the court of appeals vacate that order, arguing that
    Mackley’s briefing contained more than “technical” errors because
    Mackley had not attached the relevant order from Husband’s case.
    According to Husband, this failure meant that Husband was not a
    party to the appeal and that the requested amendments could not
    cure that defect. The court denied Husband’s request to vacate its
    prior order.
    ¶27 After the court of appeals certified the consolidated case to
    us, we issued an order allowing the parties to submit replacement
    8
    Cite as: 
    2019 UT 74
                             Opinion of the Court
    briefs. All of the parties did so. 8 Mackley’s replacement brief
    included Husband on the caption page and certificate of service. It
    also attached the relevant orders from Husband’s case as addenda.
    Husband and Mother acknowledge that Mackley corrected these
    procedural errors in his replacement brief, but they argue that doing
    so violated our replacement briefing order. That order stated that the
    parties could elect to submit replacement briefs “if the posture before
    the [s]upreme [c]ourt creates a material difference in the argument
    presented.” It went on to explain that the order should “not be
    construed to excuse compliance with otherwise-applicable principles
    or rules of appellate review (e.g., preservation in the trial court).”
    ¶28 We conclude that Husband and Mother have failed to
    demonstrate that they were prejudiced by any of Mackley’s alleged
    errors. After Mother’s counsel asked why Husband’s counsel had
    not been served a brief, Mackley emailed him a copy. Mackley then
    moved the court of appeals to amend the caption and service list on
    his original brief, which the court granted. After the case was
    certified to this court, Mackley attached the relevant orders from
    both cases as addenda to his replacement brief—orders that had
    been included in the notice of appeal that Mackley filed in
    Husband’s case.
    ¶29 Husband and Mother have not cited any rule or case law
    that these procedural errors require striking Mackley’s replacement
    brief. Indeed, the only case law they cite relates to reply, not
    replacement, briefs. Yet the parties have not explained how the
    issues presented in those cases are analogous to the one at hand. We
    conclude that any alleged procedural errors have been rectified and
    are thus harmless. Accordingly, we deny the motion to strike.
    II. VOLUNTARY DENIAL OF PATERNITY
    ¶30 Mackley contends that the district court erred in allowing
    Husband to rescind the denial under theories of mutual and
    unilateral mistake of fact. Specifically, he argues that the mistake
    cited by the district court was not a mistake of fact but rather a
    mistake regarding the legal consequences of signing the declaration
    and denial. We agree.
    ¶31 Relevant here, under the UUPA a presumed father may
    move to rescind a voluntary denial of paternity by filing a rescission
    document within sixty days after the effective date of the denial.
    _____________________________________________________________
    8   Mother filed a replacement brief, which Husband joined.
    9
    MACKLEY v. OPENSHAW
    Opinion of the Court
    UTAH CODE § 78B-15-306(1)(a). “After the period for rescission under
    Section 78B-15-306 has expired,” as occurred here, “a signatory of a
    declaration of paternity or denial of paternity . . . may commence a
    proceeding to challenge the declaration or denial only on the basis of
    fraud, duress, or material mistake of fact.” 
    Id. § 78B-15-307(1).
        ¶32 Husband moved to rescind the denial under theories of
    duress and material mistake of fact. Without addressing duress, the
    district court concluded that the denial should be rescinded due to
    mutual and unilateral mistakes of fact.
    ¶33 A party seeking to rescind an agreement based on a mutual
    mistake of fact must show, by clear and convincing evidence, that
    “both parties, at the time of contracting, share[d] a misconception
    about a basic assumption or vital fact upon which they based their
    bargain.” Bergmann v. Bergmann, 
    2018 UT App 130
    , ¶ 14, 
    428 P.3d 89
    (emphasis added) (citation omitted) (internal quotation marks
    omitted); see also UTAH CODE § 78B-15-112 (“The standard of proof in
    a trial to determine paternity is ‘by clear and convincing evidence.’”);
    
    id. § 78B-15-307(2)
    (“A party challenging a declaration of paternity or
    denial of paternity has the burden of proof.”). A mutual mistake
    “can provide the basis for equitable rescission” of an agreement
    “even when the contract appears on its face to be a ‘complete and
    binding integrated agreement.’” Burningham v. Westgate Resorts, Ltd.,
    
    2013 UT App 244
    , ¶ 12, 
    317 P.3d 445
    (citation omitted).
    ¶34 As to mutual mistake, in its order granting Husband’s
    motion to rescind the denial, the district court found that Mother,
    Husband, and Mackley were all unaware that Husband would be
    required to sign the denial. Furthermore, it found that they all
    shared the mistaken belief that the purpose of signing the
    declaration and denial was to add Mackley’s name to the child’s
    birth certificate, not declare Mackley’s paternity of the child and
    thereby terminate Husband’s legal rights as the presumed father.
    According to the court, the parties were mistaken about the legal
    consequences of signing the form because the form failed to clearly
    state them and because Husband’s mistaken belief that he was
    preserving his rights as the presumed father was reinforced by an
    employee of the health department. The court thus determined that
    none of the parties intended for the declaration and denial to have
    the effect that they did.
    ¶35 In addition, the district court noted that permitting
    Husband to terminate his fundamental rights to the child without
    that waiver being knowing and intentional would be inconsistent
    with Utah law. (Citing UTAH CODE § 78A-6-514(3).) The court then
    10
    Cite as: 
    2019 UT 74
                              Opinion of the Court
    concluded that the circumstances surrounding the execution of the
    denial demonstrated that Husband had not knowingly and
    voluntarily waived his parental rights.
    ¶36 A party may also rescind an agreement based on unilateral
    mistake of fact. To do so, the rescinding party must establish four
    elements: (1) that the mistake is “of so grave a consequence” that it
    would be “unconscionable” to enforce the contract as it was made;
    (2) that the mistake was made as to a matter that “relate[s] to a
    material feature of the contract”; (3) that the mistake “occurred
    notwithstanding the exercise of ordinary diligence by the party
    making the mistake”; and (4) that rescission will not “serious[ly]
    prejudice” the other party other than “the loss of his bargain.” Briggs
    v. Liddell, 
    699 P.2d 770
    , 773 (Utah 1985); see also John Call Eng’g, Inc. v.
    Manti City Corp., 
    743 P.2d 1205
    , 1209–10 (Utah 1987).
    ¶37 As to unilateral mistake, the district court determined that
    despite exercising ordinary diligence of a person of his education
    and experience, Husband was mistaken as to the legal consequences
    of the denial. In so concluding, the court found that Husband was
    not provided any verbal or written notice that signing the denial
    would result in a relinquishment of his parental rights and that the
    advice given by the health department employee had misled him.
    Based on those circumstances, the court concluded that enforcing the
    denial would be unconscionable and that rescinding it would not
    result in prejudice to Mackley. Accordingly, the court granted
    Husband’s motion to rescind.
    ¶38 We hold that the district court erred in allowing Husband
    to rescind the denial because any mistake (mutual or unilateral)
    related to the legal consequences of signing the form, not to any
    underlying facts. The premise of both of these equitable rescission
    doctrines is that they relate to mistakes of fact, not law. And under
    Utah law, “each party has the burden to read and understand the
    terms of a contract before he or she affixes his or her signature to it.
    A party may not sign a contract and thereafter assert ignorance or
    failure to read the contract as a defense.” John Call Eng’g, 
    Inc., 743 P.2d at 1208
    .
    ¶39 This analysis applies here even though a voluntary
    declaration of paternity is not a typical contract between two parties.
    Here, the legal consequences of Husband signing the denial arise
    both from the language on the form and from the Utah Code. The
    UUPA provides that once executed and filed, a declaration of
    paternity “is equivalent to a legal finding of paternity of a child and
    confers upon the declarant father all of the rights and duties of a
    11
    MACKLEY v. OPENSHAW
    Opinion of the Court
    parent.” UTAH CODE § 78B-15-305(1). While we agree that the form
    could be updated to clarify its contents and legal consequences to
    signatories, 9 Husband had a duty to read and understand the form
    he was signing. The form advises signatories that they should be
    “provided verbal and written notice of the legal consequences of and
    the alternatives to signing” the form. The court essentially found that
    Husband did not understand the legal consequences of the denial or
    its meaning under section 78B-15-305(1). But ignorance of controlling
    law and the legal effect of signing the form are not mistakes of fact.
    The sole mistake that seems factual is whether or not Husband
    actually did receive that verbal or written notice from the health
    department employee. But in signing the denial, Husband affirmed
    that he had. If he had not received the notice, Husband had the
    burden to inquire further or consult with legal counsel. He cannot
    claim ignorance as to the legal consequences of signing the denial.
    We therefore reverse Husband’s rescission of the denial and remand
    to the district court.
    III. STANDING
    ¶40 Mackley contends that the district court erred when it
    denied him standing to challenge Husband’s presumed paternity
    under the UUPA and the common-law Schoolcraft test. 10 However,
    this issue is now moot. Because we conclude that the district court
    erred in allowing Husband to rescind the denial, it remains in effect
    and functions as the equivalent of “a legal finding of the
    _____________________________________________________________
    9 Our holding should not be construed as approval of the form
    used in this case. Given the significant legal consequences to
    signatories of a declaration and denial of paternity, we are
    persuaded that efforts should be made to improve the clarity of the
    form. For instance, even though the definition of “presumed father”
    was not altered when the UUPA was renamed and renumbered, it is
    concerning that the form had not been updated to reflect the correct
    section of the statute.
    10 Mother and Husband argue that although the district court
    referenced Schoolcraft, it actually applied Utah Code section
    78B-15-608, which they argue is modeled after the policy
    considerations set out in Schoolcraft. We are not persuaded. It is clear
    from the district court’s order that it was applying Schoolcraft, which
    has been preempted by the UUPA. Accordingly, we conclude that
    any reliance on the prior common-law test was erroneous.

    § 78B-15-305(3), and, correspondingly, “establish[es] [Mackley’s]
    paternity of the child” as the declarant father, see 
    id. §§ 78B-15-301,
    -302(1)(f).
    ¶41 However, we note that even if we were to conclude that the
    denial was properly rescinded, Mackley would nevertheless have
    standing. In a companion case that also issues today, Castro v. Lemus,
    we hold that the UUPA grants standing to alleged fathers like
    Mackley.

    CONCLUSION
    ¶42 We conclude that the district court erred in allowing
    Husband to rescind the denial under theories of mutual and
    unilateral mistake of fact. Husband’s denial thus remains in effect.
    Mackley’s argument regarding standing is moot, but we note that
    our holding in Castro v. Lemus, 
    2019 UT 71
    , --- P.3d ---, which also
    issues today, would confer standing upon him in the absence of the
    denial. Accordingly, we vacate the order allowing for rescission and
    remand to the district court for further proceedings consistent with
    this opinion.
