You may be a father who has not been allowed to see his child. You may be a mother who needs the law to say, on paper, who the other parent is. Either way, waiting on someone else to do the right thing is exhausting.
A St. Petersburg paternity attorney at Khonsari Law Group can establish legal parentage under Florida law and ask the court for a parenting plan and a timesharing schedule. We represent both mothers and fathers in Pinellas County, from the first filing through the final order.

Do you need a lawyer to establish paternity in Florida?
Not every paternity case needs a lawyer, but most contested ones do. If both parents agree and simply want the father named, a signed form may be enough. The moment one parent disagrees, or the father wants enforceable time with his child, the case belongs in circuit court and the paperwork has to be right the first time.
Paternity in Florida is not one decision. It is two. First the court decides who the legal parent is. Then it decides what that parent gets. Skipping the second step is the single most common mistake we see in Pinellas County paternity files.
What are the four ways paternity is established in Florida?
Florida recognizes four paths, and they do not carry the same weight. Chapter 742 of the Florida Statutes governs determination of parentage, and the route you take shapes what you can enforce later.
| Path | How it happens | What it gives you | What it does not give you |
|---|---|---|---|
| Marriage at birth | The husband is entered on the birth certificate under Fla. Stat. 382.013(2) | Legal parentage, no filing needed | Nothing further is automatic if the parents later separate |
| Acknowledgment of Paternity | Both parents sign the Department of Health form (DH 432), often at the hospital | Legal parentage and natural guardian status | No timesharing schedule, no parenting plan |
| Administrative order | The Department of Revenue opens a case under Fla. Stat. 409.256 | Legal parentage and a support order | No parental responsibility, no timesharing |
| Circuit court petition | A parent files a Petition to Determine Paternity in the Sixth Judicial Circuit | Parentage plus a parenting plan, timesharing, and decision making | Requires a filed case and a judge's signature |
Signing at the hospital
The Acknowledgment of Paternity is the fastest route. It is also binding faster than most parents realize.
Either signer can cancel it within 60 days, or until the date of the first court or administrative proceeding about the child, whichever comes first.
After that window closes, the acknowledgment stands as an establishment of paternity. From then on it can only be challenged for fraud, duress, or a material mistake of fact under Fla. Stat. 742.10.
Filing in circuit court
A court petition is the only path that produces an enforceable parenting plan. It is also the path that lets a judge address parental responsibility, the child's surname, and the financial obligations both parents owe. For most unmarried fathers in St. Petersburg, this is the filing that actually changes daily life.
Does signing the birth certificate give a father timesharing rights?
No. Being named on the birth certificate makes a man a legal parent. It does not give him a single enforceable overnight.
Under Fla. Stat. 744.301, a father who has established paternity becomes a natural guardian of his child. But an enforceable schedule still requires a parenting plan entered by the court under Fla. Stat. 61.13. Until that order exists, the mother is entitled to primary residential care, and a father who keeps the child past an agreed pickup has no order to point to.
This is why fathers who "did everything right" at the hospital still call us three years later, locked out of decisions about school and medical care. The form was correct. The case was never filed.
What does a Florida paternity case decide?
A paternity case decides parentage first, then everything that follows from it. In a single filing, the court can address:
- Parental responsibility. Who makes major decisions about school, medical care, and religious upbringing. Florida uses shared parental responsibility as the starting point.
- A parenting plan and timesharing schedule. Since 2023, Florida law starts from a rebuttable presumption that equal timesharing is in the child's best interests. A parent who wants a different split has to show why, by a preponderance of the evidence.
- Financial support for the child. The court addresses the child support obligation as part of the same case, because parentage and support are decided together under Florida law.
- Practical details that matter later. The child's surname, how the parents exchange information, and how travel and holidays work.
If your case also involves a marriage that is ending, the same issues are handled inside a dissolution of marriage instead, and our timesharing and parental responsibility page covers how those schedules are built.

How long do you have to file a paternity case in Florida?
You generally have until four years after the child turns 18. Florida's limitations statute, Fla. Stat. 95.11, runs the clock from the date the child reaches the age of majority, which means a paternity action can usually be brought at any point during childhood and for four years after.
That sounds generous. In practice it is not. Every year without an order is a year of decisions made without you, and Florida judges look closely at the relationship that already exists when they build a timesharing schedule. Delay is rarely neutral.
What if you signed and later learned you are not the father?
Florida allows disestablishment, but the requirements are strict and the window is real. Under Fla. Stat. 742.18, a man asking a court to disestablish paternity must file a petition supported by:
- An affidavit that newly discovered evidence came to light after the original determination
- Genetic test results obtained within 90 days before filing, or an affidavit explaining why he could not obtain a sample
- An affidavit showing he is current on his support obligation, or has substantially complied with it
The court then has to find that he did not adopt the child, did not prevent the biological father from asserting his rights, and that the child was under 18 when the petition was filed. Miss one element and the petition fails. This is not a filing to attempt alone.
DNA testing standards in a Florida paternity case
Florida uses two different thresholds, and they are easy to confuse. In a circuit court case, Fla. Stat. 742.12 provides that a statistical probability of 95 percent or more creates a rebuttable presumption that the tested man is the biological father. Results that exclude him require dismissal with prejudice.
In an administrative case run by the Department of Revenue, the standard is higher at 99 percent. A home test kit ordered online does not meet either standard. Courts require testing through an approved provider with a documented chain of custody, which is the record showing who handled the sample at every step.
Filing a paternity case in Pinellas County
Pinellas County paternity cases are filed with the Clerk of the Circuit Court and heard in Florida's Sixth Judicial Circuit, which covers Pinellas and Pasco counties. Filings are accepted at the St. Petersburg Judicial Building on First Avenue North, and family matters are also heard at the Pinellas County Justice Center in Clearwater.
The Pinellas County Clerk of the Circuit Court handles paternity, dissolution of marriage, adoption, and name change filings. Knowing which judge sets what, and how each division handles case management, saves families weeks. That familiarity is not something you can read off a website.
Local courtroom experience behind a paternity filing
Paternity cases turn on credibility, and credibility is built in the courtroom.
Rohom Khonsari is a former Assistant State Attorney who has spent his career in Tampa Bay courtrooms. He is an Avvo Client Choice winner, and Khonsari Law Group is BBB A+ accredited. His analysis has been sought by ABC Action News, Bay News 9, the Tampa Bay Business Journal, and the Tampa Bay Times.
What that means for your case is practical. We know how Pinellas judges read a proposed parenting plan. We know which fights are worth having and which ones cost you goodwill you will need later. And we represent both sides of these cases, so we can tell you honestly how your position is likely to be received.
Paternity questions people ask before hiring a lawyer
Can a mother refuse a DNA test in Florida?
Not once a case is filed. A court can order genetic testing, and a parent who refuses without cause risks the judge drawing a conclusion against them. Before a case is filed, there is no legal obligation to test, which is one reason fathers file rather than negotiate.
Do I still have to pay if I was never married to the mother?
Yes. In Florida, a support obligation follows legal parentage, not marriage. Once paternity is established by any of the four routes, the financial obligation attaches the same way it would for married parents.
Can we agree on a schedule without going to court?
You can agree, but the agreement is not enforceable until a judge signs it. Many St. Petersburg parents reach terms through mediation and then submit the parenting plan for approval, which keeps the process shorter and less adversarial than a contested hearing.
What if the other parent has moved out of Florida?
Florida can usually still hear the case if the child lives here, and interstate rules govern which state decides parenting issues. Cases with an out-of-state parent involve service, jurisdiction, and travel provisions that are worth reviewing with a lawyer before you file.
Can paternity be established after the father has died?
Sometimes, and it usually arises in an estate matter rather than a family case. These filings involve different deadlines and different proof, so they should be reviewed quickly rather than left for later.
Your child's legal parentage is worth doing correctly
A name on a form is not the same as a relationship the law will protect. The families who come through paternity cases in the strongest position are the ones who treated the first filing as the foundation for the next fifteen years, not as paperwork.
