A father dies in Florida without a will. Adult children come forward who were never legally recognized as his during his lifetime. Everyone assumes a DNA test will settle it.
It does not. In Florida, whether those children inherit usually turns on a date rather than on biology, and the date is often decades in the past. This article explains which door the law leaves open, which one closes on a deadline, and why a 99.8% DNA match has already failed to save one claimant in a Florida appellate court.
The three doors under section 732.108(2)
For intestate succession, a person born out of wedlock is a descendant of the father only if one of three things is true. Section 732.108(2), Florida Statutes, provides that the person is also a descendant of his or her father, and one of the natural kindred of all members of the father’s family, if:
(a) The natural parents participated in a marriage ceremony before or after the birth of the person born out of wedlock, even though the attempted marriage is void.
(b) The paternity of the father is established by an adjudication before or after the death of the father. Chapter 95 shall not apply in determining heirs in a probate proceeding under this paragraph.
(c) The paternity of the father is acknowledged in writing by the father.
Most adult children in this position are looking at door (b), an adjudication of paternity inside the probate, or door (c), a written acknowledgment by the father.
The four-year rule, and where it came from
Florida imposes a four-year limitations period on “an action relating to the determination of paternity, with the time running from the date the child reaches the age of majority.” Fla. Stat. § 95.11(3)(a). Four years after an eighteenth birthday means the window generally closes at age 22.
For years the open question was whether that deadline applied inside a probate case at all. The Florida Supreme Court answered it in In re Estate of Smith, 685 So. 2d 1206 (Fla. 1996). A sixty-year-old woman sought to establish that the decedent was her father so that she could inherit. The Court held the four-year period applied, and rejected the argument that section 732.108(2)(b) created a separate cause of action running from the father’s death. The Court was blunt about why. Otherwise “a paternity claim could be strategically delayed until the death of the putative father, thereby depriving him of the opportunity to deny the claim.” Id. at 1208.
What the 2009 amendment changed
The Legislature responded in 2009 by adding one sentence to section 732.108(2)(b): “Chapter 95 shall not apply in determining heirs in a probate proceeding under this paragraph.” Ch. 2009-115, Laws of Fla.
That sentence matters enormously. For an adjudication of paternity brought inside the probate proceeding, the four-year deadline no longer applies at all.
The trap: the amendment does not reopen a door that already closed

Here is where families are caught. Florida’s appellate courts have held, repeatedly, that the 2009 amendment operates going forward only. If the four-year window had already run out before the amendment became law, the claim was already dead, and the amendment did not revive it.
The reason is constitutional rather than technical. Once a limitations period has run, the other side acquires a vested property right to be free of the claim. As the Third District put it, “once a claim has been extinguished by the applicable statute of limitations, the claim cannot be revived because a constitutionally protected property right to be free from the claim has vested.” Rose v. Sonson, 208 So. 3d 136, 139 (Fla. 3d DCA 2016).
Three decisions show how unforgiving this is.
- Rose v. Sonson, 208 So. 3d 136 (Fla. 3d DCA 2016). Born in 1964, he reached majority in 1982 and his window closed in 1986. His father died in 2012. Claim barred.
- Dixon v. Bellamy, 252 So. 3d 349 (Fla. 3d DCA 2018). Born in 1959, her claim was extinguished in 1981. An avuncular DNA test showed a 99.8% likelihood that the decedent’s brother was her uncle. Claim still barred.
- Robinson v. Robinson, 298 So. 3d 1202 (Fla. 3d DCA 2020). Born in 1980, she reached majority in 1998 and her claim was extinguished in 2002. The father died in 2004 and she filed in 2016. The probate court granted DNA testing on fairness grounds and was reversed. A probate court sitting in equity cannot set the limitations period aside.
The practical dividing line is age 22 measured against 2009. If the four-year window had already expired before the 2009 amendment took effect, door (b) is closed. If it had not, door (b) is open and no deadline applies to it.
For a family today, that generally means a claimant who turned 22 before 2009, which is to say someone born before roughly the middle of 1987, faces a serious limitations problem on the adjudication route. Anyone younger usually does not. Because the outcome turns on exact dates, the birth date and the amendment’s effective date should both be confirmed rather than estimated.
The written acknowledgment route, and a warning about it

Door (c) asks a different question. Did the father acknowledge paternity in writing? This is not a formality. A written acknowledgment does not merely raise a presumption. It settles paternity for purposes of intestate succession.
The standard is demanding. The writing must “directly, unequivocally and unquestionably” acknowledge paternity. In re McCollum’s Estate, 88 So. 2d 537, 540 (Fla. 1956).
The Fourth District addressed the most common form of proof in Richardson v. Richardson, No. 4D2025-2725 (Fla. 4th DCA July 1, 2026). The court held that if the decedent’s signature on a birth certificate identifying him as the father is genuine, that signature is a direct and unequivocal written acknowledgment under section 732.108(2)(c). The trial court had gone wrong by treating the birth certificate as conclusive without ever asking whether the claimant satisfied section 732.108. On remand, the burden falls on the party alleging forgery to prove it by a preponderance of the evidence.
Two cautions belong with that holding.
A name is not a signature. In White v. Marks, 325 So. 3d 160 (Fla. 5th DCA 2021), the decedent’s name appeared on the birth certificate but he had not signed it, and the certificate did not qualify. References in his will and in a pocket planner calling the claimant his adopted daughter were held to be descriptive rather than acknowledgments of paternity.
Door (c) may carry its own deadline. This is the point most often misunderstood. The 2009 amendment removed Chapter 95 from paragraph (b) only. It did not touch paragraph (c). In White, the Fifth District held that the four-year period applies to a written acknowledgment claim as well, reasoning that section 95.11 reaches any action relating to the determination of paternity. 325 So. 3d at 163. The court noted that it was writing on a relatively clean slate, and it expressly reserved the situation where the written acknowledgment was executed before the limitations period ran. But anyone treating door (c) as deadline free is relying on an assumption that a Florida appellate court has already rejected.
What this means in practice
- Pin down the birth dates first. Everything turns on when the claimant turned 22 and how that compares to 2009. Little else can be assessed until that is fixed.
- Bring the claim inside the probate. A separate action under Chapter 742 does not get the benefit of the carve out in section 732.108(2)(b).
- Hunt for writings early. A signed birth certificate, letters, insurance or benefit applications, school records, or anything else in the father’s hand can matter more than a laboratory result.
- Do not rely on DNA alone. Dixon is the cautionary tale. A 99.8% result did not overcome a deadline that had passed decades earlier.
- Move quickly. A probate has its own timetables for interested persons, independent of the paternity question, and they run from steps taken in the estate rather than from when a family learns the facts.
These cases are won and lost on dates and documents. If you believe you are the child of someone whose estate is being administered in Florida, or you are a personal representative facing a claim like this, the sooner the timeline is established the more options remain.
