(1) A grant of authority is temporary and terminates after the deploying parent returns from deployment unless the grant has been terminated before the return of the deploying parent in a record or by a written agreement signed by both the deploying parent and the other parent, or, in the absence of such a record or agreement, by court order. The grant does not create any independent, continuing right to caretaking authority, decisionmaking authority, or limited contact to an individual granted temporary custody.
(2) A nonparent granted temporary caretaking authority, decisionmaking authority, or limited contact has standing only to enforce the grant until it is terminated in a record or by a written agreement signed by both the deploying parent and the other parent, or, in the absence of such a record or agreement, by court order or under this part.
(3) If a grant of temporary authority is terminated in a record or by a written agreement signed by both the deploying parent and the other parent, a copy of the termination record or agreement shall be filed with the court and the temporary custody order shall be modified to reflect the termination. Thereafter, the deploying parent and the other parent may agree on alternative arrangements for custodial responsibility in compliance with s. 61.721, or either parent may seek an alternative arrangement for custodial responsibility under s. 61.749.
