Yes. Florida 529 Savings Plan ownership can be transferred at any time to an individual 18 years of age or older and a U.S. citizen or legal U.S. resident.
In addition, funds may be transferred from one Florida 529 Savings Plan to another for a member of the student’s family. The IRS calls this a “rollover” and allows you to do so once every 12 months for the same Beneficiary.
