FL S0166

Establishes a legal domestic partnership framework in Florida allowing two individuals aged 18+ (with at least one being a state resident) to register partnerships by filing a Declaration of Domestic Partnership with the circuit court clerk.

Grants domestic partners equivalent rights and responsibilities as married spouses regarding in-law relationships, child-related matters, and state tax law administration, while excluding federal benefits and retirement plans subject to federal regulation.

Prohibits domestic partnerships if either party is married, already has a domestic partner, or is related by blood/marriage; makes filing false information on the declaration a first-degree misdemeanor.

Creates fees of $61.50 total per domestic partnership registration (including charges for domestic violence, displaced homemaker, and general revenue funds) and establishes procedures for partnership termination effective 90 days after filing notice.

Amends domestic violence definitions to include domestic partners as "family or household members" and requires clerks to maintain public registries of all registered domestic partnerships and dissolution records.
