948.31(1)(a)1.1. A parent or other person having legal custody of the child under an order or judgment in an action for divorce, legal separation, annulment, child custody, paternity, guardianship or habeas corpus.

948.31(1)(a)2.2. The department of children and families or the department of corrections or any person, county department under s. 46.215, 46.22, or 46.23, or licensed child welfare agency, if custody or supervision of the child has been transferred under ch. 48 or 938 to that department, person, or agency.

This paragraph is not applicable if the court has entered an order authorizing the person to so take or withhold the child. The fact that joint legal custody has been awarded to both parents by a court does not preclude a court from finding that one parent has committed a violation of this paragraph.

This subsection is not applicable if legal custody has been granted by court order to the person taking or withholding the child.

948.31(3)(3) Any parent, or any person acting pursuant to directions from the parent, who does any of the following is guilty of a Class F felony:

948.31(3)(a)(a) Intentionally conceals a child from the child’s other parent.

948.31(3)(c)(c) After issuance of a temporary or final order specifying joint legal custody rights and periods of physical placement, takes a child from or causes a child to leave the other parent in violation of the order or withholds a child for more than 12 hours beyond the court-approved period of physical placement or visitation period.

948.31(4)(a)(a) It is an affirmative defense to prosecution for violation of this section if the action:

948.31(4)(a)1.1. Is taken by a parent or by a person authorized by a parent to protect his or her child in a situation in which the parent or authorized person reasonably believes that there is a threat of physical harm or sexual assault to the child;
