Few discoveries hit harder than learning — or strongly suspecting — that a child you have been supporting is not biologically yours. Florida law provides a path out of the legal and financial obligations of paternity, but it is a narrow one, walled in by deadlines, conditions, and a legislature torn between fairness to men and stability for children. Disestablishment under § 742.18 is winnable with the right facts and fatal missteps are easy to make. The Law Office of John Vernon Moore, P.A. brings over 89 years of combined experience to these delicate, high-stakes cases across Brevard County.
What Disestablishment Is — and Is Not
Disestablishment of paternity is a statutory action under § 742.18 that allows a man previously established as a child’s legal father — by acknowledgment, court order, or administrative order — to terminate that status and the child support obligation that comes with it, based on newly discovered evidence that he is not the biological father. It is not the same as contesting paternity before it is established (that is what DNA testing in a paternity case is for), and it is not available just because regret has set in. The statute is a second chance, and Florida makes second chances earn their keep.
The Requirements: Every Box Must Be Checked
A petition to disestablish paternity must include three things: an affidavit that newly discovered evidence about paternity has come to light since the original determination; the results of a scientific paternity test administered within 90 days before filing (or an allegation that the mother or child is unavailable and a request for court-ordered testing); and an affidavit that the petitioner is current on child support, or that any arrearage arose from inability to pay. Then the statute stacks conditions on top. The court must deny relief if the legal father, after learning he is not the biological father:
- Married the mother and voluntarily assumed the parental obligation
- Acknowledged paternity in a sworn statement
- Consented to being named on the birth certificate
- Voluntarily promised in writing to support the child and was required to support based on that promise
- Disregarded a notice from a state agency directing him to submit to testing
- Signed a voluntary acknowledgment of paternity under § 742.10 knowing he was not the father
The pattern is clear: the statute protects the deceived, not the informed volunteer. A man who kept acting as father after learning the truth generally forfeits the exit.
The Process in a Brevard County Court
The petition is filed in circuit court — for local families, the Moore Justice Center in Viera or the Titusville courthouse. The court reviews the affidavits, orders genetic testing if the private test is contested (a common defense move, since chain-of-custody matters), and holds a hearing. If every statutory element is satisfied and no disqualifying conduct applies, the court terminates the parent-child relationship prospectively: future child support ends. What disestablishment does not do is refund the past — support already paid is gone, and arrears that accrued before termination generally remain owed. Timing is everything: every month between discovery and filing is a month of support that will never come back, and continued voluntary parenting after discovery builds the very record that defeats the petition.
The Human Side: Think Before You File
Disestablishment ends more than a payment obligation — it legally severs the father-child relationship, including timesharing rights and inheritance. For a man who has raised a child for years, the law offers a binary choice: remain the legal father with all obligations, or cease to be a parent at all. There is no support-free fatherhood option. Some clients, after seeing the whole picture, choose to stay; others need the truth honored. With over 89 years of combined experience, our team walks through both the law and the consequences before a petition is ever drafted — and for men on the other side of the equation, we also defend disestablishment actions on behalf of mothers and children where the statutory requirements are not met.
I just learned the child is not mine. What should I do first?
Get legal advice before doing anything else — including confronting anyone or stopping support. Unilaterally stopping payments creates arrears and contempt exposure, while continued voluntary parenting after discovery can defeat a future petition. The order of operations matters enormously in these cases.
Can I get back the child support I already paid?
No. Disestablishment operates prospectively — it ends future support but does not refund past payments, and pre-termination arrears generally survive. This is the strongest reason not to delay once the truth is discovered.
Does a home DNA test satisfy the statute?
The statute requires a scientific test within 90 days of filing, and courts expect lab-grade, chain-of-custody testing. A drugstore kit may justify filing, but expect the court to order formal testing if results are contested. We coordinate testing that will hold up.
What if I signed the acknowledgment at the hospital?
A voluntary acknowledgment that became final can still be disestablished under § 742.18 — unless you signed knowing you were not the father, or continued to hold yourself out as father after learning the truth. Within the first 60 days, an acknowledgment can simply be rescinded; see our acknowledgment of paternity page.
