In Florida, an unmarried father has no enforceable rights to his child — no timesharing, no say in decisions — until paternity is legally established. And an unmarried mother cannot collect child support until the same thing happens. Establishing paternity is the legal front door to everything that follows: support, custody, insurance, inheritance, and a father’s name carrying legal weight rather than just appearing on a birth certificate. The Law Office of John Vernon Moore, P.A. brings over 89 years of combined experience to paternity cases across Brevard County, representing mothers and fathers alike.
Why Establishing Paternity Matters
When a child is born to married parents, Florida law presumes the husband is the legal father. When the parents are unmarried, the child is born with a legal father-shaped hole — even if dad signs the birth certificate and lives in the home. Until paternity is established under Chapter 742 of the Florida Statutes, the mother has sole natural custody, the father cannot enforce time with his child, and no court can order child support. Establishing paternity unlocks:
- For fathers: standing to seek a parenting plan and timesharing — including the benefit of Florida’s equal timesharing presumption once a case is filed — and the right to be consulted on major decisions
- For mothers: enforceable child support, including retroactive support up to 24 months
- For children: health insurance eligibility, Social Security and veterans benefits, inheritance rights, and access to both families’ medical histories
The Four Ways Paternity Is Established in Florida
1. Marriage. If the parents are married when the child is born, the husband is the legal father automatically. Marrying after the birth also legitimates the child when paternity is acknowledged.
2. Voluntary acknowledgment. Unmarried parents can sign a DH-511 Acknowledgment of Paternity form — usually at the hospital — which becomes final 60 days after signing. It is fast and free, but it carries the full weight of a court judgment once final, so it should not be signed amid doubt. Our acknowledgment of paternity page covers the form, the 60-day rescission window, and the risks.
3. Administrative order. The Florida Department of Revenue can establish paternity administratively based on genetic testing, primarily to set child support. It does not create a parenting plan — fathers who want timesharing still need a court case.
4. Circuit court judgment. A paternity action under § 742.011, filed in circuit court — for Brevard County families, at the Moore Justice Center in Viera or the Titusville courthouse. Either parent may file. The court can order DNA testing, adjudicate paternity, order support, and — critically — establish a parenting plan and timesharing schedule in the same case.
What Happens in a Court Paternity Case
A paternity action follows a familiar arc: petition and service, an answer, genetic testing if parentage is disputed (a simple cheek swab, with results typically excluding or confirming at 99%+ probability), and then the real work — the parenting plan and support. Once paternity is adjudicated, custody issues are decided under the same best-interests framework as any divorce, including the rebuttable presumption that equal timesharing serves the child. Support follows the income-shares guidelines in § 61.30. The court also addresses the birth certificate, the child’s name if disputed, and who claims the child for taxes. Our pages on parenting plans and support and custody after paternity walk through those pieces.
Common Situations We See in Brevard County
The father who signed the birth certificate and assumes he has rights — he does not, until paternity is established. The mother whose ex pays nothing because no order exists. The father whose relationship with the mother ended and whose access to the child ended with it. The man asked to sign an acknowledgment while unsure the child is his. The military member at Patrick Space Force Base needing to establish rights before a deployment — see our military paternity page. Each situation has a correct legal path, and with over 89 years of combined experience, our team has guided clients through all of them.
Does signing the birth certificate establish paternity in Florida?
Not by itself. For unmarried parents, legal paternity comes from a voluntary acknowledgment that has become final, an administrative order, or a court judgment. A birth certificate signature usually accompanies an acknowledgment form — it is the form, not the certificate, that creates legal fatherhood.
Is there a deadline to establish paternity?
A paternity action can generally be brought any time before the child turns 18 (and in limited circumstances afterward). But waiting has costs: retroactive child support reaches back at most 24 months, and every year without an order is a year of rights and relationships left unprotected.
Can I get a parenting plan in the same case as child support?
In a circuit court paternity action, yes — support, timesharing, and decision-making are all resolved in one case. A Department of Revenue administrative proceeding sets support only; fathers seeking time with their child need the court route.
What if the mother refuses DNA testing?
Once a paternity action is filed, the court can compel genetic testing of the mother, child, and alleged father. Refusal to comply can result in sanctions and in the court resolving the issue against the refusing party.
