744.301 Natural guardians.--
(1) The mother and father jointly are natural guardians of their own children and of their adopted children, during minority. If one parent dies, the natural guardianship shall pass to the surviving parent, and the right shall continue even though the surviving parent remarries. If the marriage between the parents is dissolved, the natural guardianship shall belong to the parent to whom the custody of the child is awarded. If the parents are given joint custody, then both shall continue as natural guardians. If the marriage is dissolved and neither the father nor the mother is given custody of the child, neither shall act as natural guardian of the child. The mother of a child born out of wedlock is the natural guardian of the child and is entitled to primary residential care and custody of the child unless a court of competent jurisdiction enters an order stating otherwise.
(2) The natural guardian or guardians are authorized, on behalf of any of their minor children, to settle and consummate a settlement of any claim or cause of action accruing to any of their minor children for damages to the person or property of any of said minor children and to collect, receive, manage, and dispose of the proceeds of any such settlement and of any other real or personal property distributed from an estate or trust or proceeds from a life insurance policy to, or otherwise accruing to the benefit of, the child during minority, when the amount involved in any instance does not exceed $5,000, without appointment, authority, or bond.
(3) All instruments executed by a natural guardian under the powers provided for in subsection (2) shall be binding on the ward.
(4)(a) In any case where a minor has a claim for personal injury, property damage, or wrongful death in which the gross settlement for the claim of the minor equals or exceeds $10,000, the court may, prior to the approval of the settlement of the minor's claim, appoint a guardian ad litem to represent the minor's interests. In any case in which the gross settlement involving a minor equals or exceeds $25,000, the court shall, prior to the approval of the settlement of the minor's claim, appoint a guardian ad litem to represent the minor's interests. The appointment of the guardian ad litem must be without the necessity of bond or a notice. The duty of the guardian ad litem is to protect the minor's interests. The procedure for carrying out that duty is as prescribed in the Florida Probate Rules. If a legal guardian of the minor has previously been appointed and has no potential adverse interest to the minor, the court may not appoint a guardian ad litem to represent the minor's interests, unless the court determines that the appointment is otherwise necessary.
(b) Unless waived, the court shall award reasonable fees and costs to the guardian ad litem to be paid out of the gross proceeds of the settlement.
