Dissolution of marriage.—
(1)No judgment of dissolution of marriage shall be granted unless one of the following facts appears, which shall be pleaded generally:
(a)The marriage is irretrievably broken.
(b)Mental incapacity of one of the parties. However, no dissolution shall be allowed unless the party alleged to be incapacitated shall have been adjudged incapacitated according to the provisions of s. 744.331 for a preceding period of at least 3 years. Notice of the proceeding for dissolution shall be served upon one of the nearest blood relatives or guardian of the incapacitated person, and the relative or guardian shall be entitled to appear and to be heard upon the issues. If the incapacitated party has a general guardian other than the party bringing the proceeding, the petition and summons shall be served upon the incapacitated party and the guardian; and the guardian shall defend and protect the interests of the incapacitated party. If the incapacitated party has no guardian other than the party bringing the proceeding, the court shall appoint a guardian ad litem to defend and protect the interests of the incapacitated party. However, in all dissolutions of marriage granted on the basis of incapacity, the court may require the petitioner to pay alimony pursuant to the provisions of s. 61.08.
