Florida permits marriage between first cousins, making it explicitly legal under state statutes. No prohibitions extend to cousins, unlike closer relatives such as siblings or parents and children.
Florida’s Marriage Statute
Florida Statute § 741.21 bans incestuous marriages involving lineal consanguinity—like parent-child or grandparent-grandchild—as well as siblings, aunts/uncles with nieces/nephews. First cousins fall under collateral consanguinity, explicitly omitted from restrictions.
This law, unchanged as of March 2026, survived a recent legislative push to ban cousin marriages. A bill amendment failed, preserving Florida’s position among 18 states allowing the practice.
Who Can Marry
First cousins, first cousins once removed, half-cousins, and even adopted cousins face no barriers. Couples apply for licenses like any others, meeting age, residency, and waiting period rules without extra scrutiny.
Out-of-state cousin marriages remain valid if performed legally elsewhere. Florida recognizes them under comity principles.
| Relationship | Legal to Marry? | Statute Reference |
|---|---|---|
| First Cousins | Yes | § 741.21 |
| Siblings | No | § 741.21 |
| Uncle/Niece | No | § 741.21 |
| Cousins Once Removed | Yes | None prohibiting |
| Adopted Cousins | Yes | None prohibiting |
Criminal Aspects
Marriage legality does not imply sexual relations lack oversight, but Florida’s incest criminal code (Chapter 826) targets lineal relatives and siblings, excluding cousins. No prosecutions occur for consensual adult cousin relationships.
Recent debates highlighted cultural surprise, yet lawmakers upheld the status quo, noting no health mandates for genetic counseling.
Recent Legislative Attempts
In early 2026, Rep. Dean Black proposed broadening bans via a health bill amendment, arguing against intra-family unions. It failed amid limited support, keeping Florida permissive compared to states like West Virginia, which banned cousins in 1955.
Public reaction mixes shock and acceptance, with media noting Florida’s alignment with states like California and New York.
Practical Steps
Obtain a marriage license from any county clerk; no blood tests or cousin disclosures required. Ceremonies follow standard protocols, valid statewide and federally recognized.
Genetic risks mirror unrelated couples statistically, per health data, though counseling remains optional.
Neighboring States Comparison
Unlike stricter neighbors—Arizona bans first-cousin marriage—Florida’s leniency aids border residents. Texas allows under 65 with affidavit, but Florida imposes no such qualifiers.
In summary, Florida law affirmatively allows cousin marriages without penalty, reflecting a hands-off approach to collateral kin.
