FL S1432

Defines "dependent adult child" as an unmarried adult incapable of self-support due to physical or mental incapacity beginning before age 18, and establishes parental responsibility for their support.

Requires parental rights to manage support and make health/safety decisions for dependent adult children to be established through guardianship proceedings under chapters 393 or 744, rather than through informal arrangements.

Allows suits to establish support for dependent adult children to be filed by the child, a parent/guardian, or a guardian advocate at any time after the child reaches age 17.5, with support continuing after age 18 if the child meets incapacity requirements.

Creates a separate support determination framework for dependent adult children based on factors including the child's income/assets, care needs related to incapacity, parental financial resources, and available government benefits and programs.

Permits courts to irrevocably assign support payments to special needs trusts or pooled trusts to preserve the dependent adult child's eligibility for means-based government benefits, and prohibits the Department of Revenue from filing petitions to establish or modify such support orders.
