Fla. Stat. ch. 742 · Determination of parentage

Paternity Lawyer in Tallahassee, FL

When parents are not married, the father has no enforceable right to time-sharing until paternity is legally established, even where he is named on the birth certificate and has raised the child.

Signing the birth certificate is not the same as having rights

This is the single most common misunderstanding we encounter. Under Florida law, when a child is born to unmarried parents, the mother is the natural guardian and has primary responsibility for the child. An acknowledgment of paternity establishes that the man is the legal father, and it creates a support obligation, but it does not by itself give him a court-ordered right to time-sharing or decision-making.

Until a court enters an order establishing paternity and a parenting plan, a father in this position has no schedule he can enforce. If the relationship ends badly and the mother stops contact, there is nothing to take to a judge. Fixing that requires filing a paternity action.

What a paternity case decides

A petition to determine paternity resolves the whole picture at once:

  • Legal fatherhood, by acknowledgment, agreement, or genetic testing.
  • A parenting plan and time-sharing schedule, applying the same best-interest analysis and the same equal time-sharing presumption that governs divorcing parents.
  • Child support under the statutory guidelines, including health insurance and child care.
  • Retroactive support, which the court can order for up to 24 months before the petition was filed.
  • The child’s surname, in some circumstances.

If you are the mother

A paternity action is also how a mother establishes a support obligation against a father who is not paying, and how she obtains a formal, enforceable schedule instead of an informal arrangement that shifts whenever there is a disagreement. Many mothers file precisely because the informality has become the problem.

Genetic testing and the limits of it

Where paternity is disputed, the court can order genetic testing, and the results are close to conclusive on the biological question. What testing does not do is resolve every legal question. Florida recognizes situations where a man who is not the biological father is nonetheless the legal father. Most importantly, a child born during a marriage is presumed to be the husband’s child, and that presumption is one of the strongest in Florida law. Disestablishing paternity is a separate proceeding with its own strict requirements and deadlines.

If you have doubts, raise them early. Delay makes these cases substantially harder, both legally and for the child.

Timing, and what courts look at

Paternity and a parenting plan are cheapest and least adversarial to establish while the parents are still cooperating, because the process then largely memorializes an arrangement that already works. Waiting until there is a dispute changes both the cost and the tone of the case considerably.

Where a schedule is being set, courts respond to demonstrated and consistent participation in a child’s life. A documented history of involvement and contribution carries real weight in that assessment.

Questions we hear every week

Common questions

I am on the birth certificate. Do I still need a paternity case?

Yes, if you want an enforceable right to time-sharing. Being named on the certificate establishes legal fatherhood and a support obligation, but it does not create a court-ordered parenting plan. Without one, you have no schedule a judge can enforce.

Can the mother move away with our child?

Until paternity and a parenting plan are established, your ability to prevent a move is very limited. Once an order is in place, Florida’s relocation statute requires either your written consent or court approval for a move of more than 50 miles lasting 60 days or more.

How far back can child support be ordered in a paternity case?

Up to 24 months before the petition is filed. The court considers the father’s income during that period and any support he actually provided.

What if I have been paying support for a child who is not mine?

Florida has a procedure to disestablish paternity and terminate support, but it has strict requirements, including newly discovered evidence, current support payments, and prompt action once the facts come to light. It is not available indefinitely, so consult an attorney quickly.

Does the father get equal time-sharing in a paternity case?

The same 2023 rebuttable presumption in favor of equal time-sharing applies. The court still works through the best-interest factors, and the practical realities carry weight: the child’s age, the distance between homes, and each parent’s prior involvement.
