Florida Paternity Attorney
Paternity for children born to unmarried parents is governed by Fla. Stat. chapter 742. § 742.10(1) makes chapter 742 “the primary jurisdiction and procedures for the determination of paternity for children born out of wedlock.” Establishing paternity is a separate step from obtaining time-sharing: under § 742.10(5), a parenting plan “must be established in an action brought under s. 742.011.”
Quick Answer
How do you establish paternity in Florida?
Four routes, under Fla. Stat. § 742.10(1): a court adjudication; an affidavit or stipulation of paternity filed with the clerk; a notarized or two-witness voluntary acknowledgment signed under penalty of perjury; or an administrative adjudication by the Department of Revenue under s. 409.256. A signed acknowledgment may be rescinded within 60 days, and after that it “may be challenged in court only on the basis of fraud, duress, or material mistake of fact” — § 742.10(4).
Chapter 742 was amended by ch. 2023-209 and ch. 2023-213, which tightened the link between a paternity judgment and a parenting plan. The full chapter is at leg.state.fl.us — Fla. Stat. ch. 742.
How is paternity established in Florida? (§ 742.10(1))
§ 742.10(1) recognises establishment where paternity is determined in an adjudicatory hearing; where “an affidavit acknowledging paternity or a stipulation of paternity is executed by both parties and filed with the clerk of the court”; where “an affidavit, a notarized voluntary acknowledgment of paternity, or a voluntary acknowledgment of paternity that is witnessed by two individuals and signed under penalty of perjury as provided for in s. 382.013 or s. 382.016 is executed by both parties”; or where “paternity is adjudicated by the Department of Revenue as provided in s. 409.256.” Any of the four “constitutes the establishment of paternity for purposes of this chapter.”
Who may bring the action is broad. § 742.011 permits “[a]ny woman who is pregnant or has a child, any man who has reason to believe that he is the father of a child, or any child” to bring proceedings in circuit court “to determine the paternity of the child when paternity has not been established by law or otherwise.”
Can a voluntary acknowledgment of paternity be undone? (§ 742.10(1), (4))
There is a 60-day window, then a much higher bar. Under § 742.10(1), a notarized or two-witness voluntary acknowledgment “creates a rebuttable presumption, as defined by s. 90.304, of paternity and is subject to the right of any signatory to rescind the acknowledgment within 60 days after the date the acknowledgment was signed or the date of an administrative or judicial proceeding relating to the child… whichever is earlier.”
After that, § 742.10(4) controls: the acknowledgment “shall constitute an establishment of paternity and may be challenged in court only on the basis of fraud, duress, or material mistake of fact, with the burden of proof upon the challenger,” and support obligations “may not be suspended during the challenge, except upon a finding of good cause by the court.” Signing the hospital paperwork is therefore a legal act with a hard deadline attached. (official text of § 742.10.)
What DNA result creates a presumption of paternity? (§ 742.12(4))
95 percent. § 742.12(4): “A statistical probability of paternity of 95 percent or more creates a rebuttable presumption, as defined by s. 90.304, that the alleged father is the biological father of the child,” and if that presumption is not rebutted “the court may enter a summary judgment of paternity.” Conversely, “[i]f the test results show the alleged father cannot be the biological father, the case shall be dismissed with prejudice.”
Objections are on a clock. § 742.12(3) requires that any objection to the test results “be made in writing and… filed with the court at least 10 days prior to the hearing”; absent objection, the results come in “without the need for predicate to be laid or third-party foundation testimony.” The court may order testing on its own motion under § 742.12(1), and § 742.12(7) assigns the cost “in proportions and at times determined by the court.”
Does establishing paternity give a father time-sharing? (§ 742.10(5))
Not by itself — and this is the most consequential rule in the chapter. § 742.10(5): “Regardless of whether paternity is established in an action under s. 742.011 or this section, the determination of parental responsibility and child support and the creation of a parenting plan and time-sharing schedule must be established in an action brought under s. 742.011.” A father who signed an acknowledgment at the hospital has established paternity and has no schedule. § 742.011 confirms the route: “[a]fter the birth of the child, a parent may request a determination of parental responsibility and child support and for the creation of a parenting plan and time-sharing schedule pursuant to chapter 61.”
What happens if the judgment contains no parenting plan? (§ 742.031(2))
The statute fills the gap against the absent parent. § 742.031(2): “If a judgment of paternity contains only a child support award with no parenting plan or time-sharing schedule, the obligee parent shall receive all of the time-sharing and sole parental responsibility without prejudice to the obligor parent. If a paternity judgment contains no such provisions, the mother shall be presumed to have all of the time-sharing and sole parental responsibility.” A support-only order is therefore not neutral.
Does the equal time-sharing presumption apply to unmarried parents? (§ 61.13(2)(c)1.)
Yes, once a chapter 61 parenting determination is before the court. Because § 742.011 and § 742.10(5) route parenting decisions into chapter 61, the standard is the same one that applies in a divorce: § 61.13(2)(c)1., effective 1 July 2023, creates “a rebuttable presumption that equal time-sharing of a minor child is in the best interests of the minor child,” rebuttable only “by a preponderance of the evidence.” The schedule is then measured against the best-interests factors in § 61.13(3). Relocation afterwards is governed by § 61.13001 — 50 miles, 60 consecutive days.
How is child support set in a paternity case? (§ 742.031(1), § 61.30)
By the same guidelines used in divorce. § 742.031(1) directs the court to “order either or both parents owing a duty of support to the child to pay support under chapter 61,” and requires the court, on a party’s motion, to “issue… a temporary order requiring child support for a minor child under s. 61.30 pending an administrative or judicial determination of parentage if there is clear and convincing evidence of paternity on the basis of genetic tests or other evidence.”
§ 61.30(1)(a) makes the guideline figure the amount that “presumptively establishes the amount the trier of fact must order,” with any variance beyond 5 percent permitted “only upon a written finding explaining why ordering payment of such guideline amount would be unjust or inappropriate.” The overnight count then moves the number: § 61.30(11)(b)8. defines “substantial amount of time” as time-sharing of “at least 20 percent of the overnights of the year.” Model it with our Florida child support calculator. The court may also order the father to pay “hospital or medical expenses, cost of confinement, and any other expenses incident to the birth of the child” (§ 742.031(1)).
Where is a Florida paternity case filed? (§ 742.021(1))
§ 742.021(1): “The proceedings must be in the circuit court of the county where the plaintiff resides or the county where the defendant resides.” The complaint “shall assert sufficient facts charging the paternity of the child,” and § 742.021(2) requires the clerk to issue a notice about the Florida Putative Father Registry with service of the petition.
Can paternity be disestablished in Florida? (§ 742.18)
Yes, but the statute is demanding. § 742.18(1) requires a petition supported by an affidavit of newly discovered evidence, plus “[t]he results of scientific tests… administered within 90 days prior to the filing of such petition” showing he cannot be the father, plus an affidavit that the petitioner is current on child support or has substantially complied. § 742.18(2) then requires the court to find all of seven things, including that “[t]he male ordered to pay child support has not adopted the child” and that “[t]he child was younger than 18 years of age when the petition was filed.”
§ 742.18(3) bars relief outright where, after learning he is not the biological father, the man acknowledged paternity in a sworn statement, consented to be named on the birth certificate, promised in writing to support the child, disregarded a written directive to submit to testing, or signed a voluntary acknowledgment under s. 742.10(4). Relief, when granted, is prospective only: § 742.18(5) limits it to “prospective child support payments and termination of parental rights, custody, and visitation rights” and states that the section “shall not be construed to create a cause of action to recover child support that was previously paid.” And under § 742.18(10), if relief is denied “the court shall assess the costs of the action and attorney’s fees against the petitioner.” (official text of § 742.18.)
What is the Florida Putative Father Registry? (§ 63.054)
A deadline-driven filing that protects an unmarried father against an adoption proceeding. § 63.054(1) provides that to preserve the right to notice and consent to an adoption, an unmarried biological father must file a notarized claim of paternity with the registry maintained by the Office of Vital Statistics, and that the claim “may be filed at any time before the child’s birth, but may not be filed after the date a petition is filed for termination of parental rights.” Missing it has a second consequence: that failure “also bars him from filing a paternity claim under chapter 742.”
What if paternity was established in another state? (§ 742.105)
Florida gives it full effect. § 742.105: a final order of paternity entered in a foreign jurisdiction, or an affidavit acknowledging paternity signed in another state under its procedures, “shall be given the same legal effect as if such final order was entered or affidavit was signed pursuant to this chapter,” and a certified copy “shall be conclusive evidence of paternity.”
Do the parents’ later marriage or an adoption change anything? (§ 742.091, § 742.07)
Both end the case, in different ways. § 742.091 provides that if the mother and the reputed father “shall at any time after its birth intermarry, the child shall in all respects be deemed and held to be the child of the husband and wife, as though born within wedlock,” and the cause is dismissed on payment of costs and fees. § 742.07 is shorter: on adoption of the child “by some person other than the father, the liability of the father for the support of the child shall be terminated.”
Can a paternity order be changed later? (§ 742.06)
Yes. § 742.06 provides that the court “shall retain jurisdiction of the cause for the purpose of entering such other and further orders as changing circumstances of the parties may in justice and equity require,” and confirms that “[m]odifications and enforcement of child support, time-sharing, and support for a dependent adult child are determined under chapter 61.” Enforcement of arrears runs through § 742.08, under which a default may be reduced to a judgment that “shall be a lien upon all property of the defendant both real and personal.”
Who pays the attorney’s fees in a paternity case? (§ 742.045)
The chapter has its own fee statute. § 742.045: the court may, “after considering the financial resources of both parties, order a party to pay a reasonable amount for attorney’s fees, suit money, and the cost to the other party of maintaining or defending any proceeding under this chapter, including enforcement and modification proceedings,” and expressly provides that such an application “shall not require corroborating expert testimony.” Once parenting issues move into chapter 61, the parallel provision is § 61.16(1).
One privacy rule is easy to overlook: § 742.09 makes it unlawful, except for service by publication, for a newspaper, magazine, radio station, or other publication “to publish the name of any of the parties to any court proceeding to determine paternity,” a first-degree misdemeanor.
How Pazos Law Group handles a Florida paternity case
Nadia Pazos has practiced Florida family law for more than 20 years and handles paternity matters from the firm’s Coral Gables office, in English and Spanish. For fathers, the sequence is usually the same: confirm whether paternity is already established under § 742.10(1), then file the § 742.011 action that § 742.10(5) requires before any schedule can exist — before § 742.031(2) operates by default. For mothers, it is establishing support under § 61.30 and, where needed, temporary support under § 742.031(1). See also Florida fathers’ rights and child custody and time-sharing.
Frequently Asked Questions
How do you establish paternity in Florida?
§ 742.10(1) recognises four routes: a court adjudication; an affidavit or stipulation of paternity filed with the clerk; a notarized or two-witness voluntary acknowledgment signed under penalty of perjury as provided in s. 382.013 or s. 382.016; or an administrative adjudication by the Department of Revenue under s. 409.256.
Can a father get time-sharing just by signing the birth certificate?
No. § 742.10(5) provides that “[r]egardless of whether paternity is established in an action under s. 742.011 or this section, the determination of parental responsibility and child support and the creation of a parenting plan and time-sharing schedule must be established in an action brought under s. 742.011.” Establishing paternity and obtaining a schedule are two separate steps.
How long do I have to cancel a voluntary acknowledgment of paternity?
Sixty days. § 742.10(1) allows any signatory to rescind within 60 days after signing or the date of a related administrative or judicial proceeding, whichever is earlier. After that, § 742.10(4) permits a challenge “only on the basis of fraud, duress, or material mistake of fact, with the burden of proof upon the challenger.”
What DNA percentage proves paternity in Florida?
95 percent. § 742.12(4) provides that “[a] statistical probability of paternity of 95 percent or more creates a rebuttable presumption, as defined by s. 90.304, that the alleged father is the biological father of the child,” and permits summary judgment if the presumption is not rebutted. If the tests exclude him, the case “shall be dismissed with prejudice.”
Do unmarried parents get the 50/50 time-sharing presumption in Florida?
Yes, once the parenting question is before the court. § 742.011 and § 742.10(5) route parenting determinations into chapter 61, where § 61.13(2)(c)1., effective 1 July 2023, creates “a rebuttable presumption that equal time-sharing of a minor child is in the best interests of the minor child,” rebuttable by a preponderance of the evidence.
Can you disestablish paternity in Florida?
Under § 742.18, yes, but the requirements are strict: newly discovered evidence, scientific test results “administered within 90 days prior to the filing of such petition,” and current or substantially compliant child support. § 742.18(2) also requires that the man has not adopted the child and that the child was under 18 when the petition was filed. Relief is prospective only under § 742.18(5).
What happens if a paternity judgment has no parenting plan?
§ 742.031(2) resolves it against the absent parent: if the judgment contains only a support award, “the obligee parent shall receive all of the time-sharing and sole parental responsibility without prejudice to the obligor parent,” and if the judgment contains no such provisions, “the mother shall be presumed to have all of the time-sharing and sole parental responsibility.”
Where do I file a paternity case in Florida?
§ 742.021(1) requires that the proceedings “be in the circuit court of the county where the plaintiff resides or the county where the defendant resides.” The complaint must assert sufficient facts charging paternity, and the clerk issues a notice regarding the Florida Putative Father Registry with service.
Does a paternity order from another state count in Florida?
Yes. § 742.105 gives a final foreign paternity order, or an acknowledgment signed in another state under its procedures, “the same legal effect as if such final order was entered or affidavit was signed pursuant to this chapter,” and makes a certified copy “conclusive evidence of paternity.”
