La. C.C.P. art. 4501. — Rights of parents during marriage over minor's property

A. Except as otherwise provided by law, during marriage, the parents shall seek court approval to alienate, encumber, or lease the property of the minor, incur an obligation of the minor, or compromise a claim of the minor, in the same manner and using the same procedure as a tutor. The parents shall petition jointly, unless one parent is mentally incompetent, interdicted, or imprisoned, or is an absent person, in which case the other parent shall petition alone. One parent may also petition alone, with permission of the court, if the other parent fails or refuses to do so.

B. An ascendant having parental authority shall be considered a parent for the purposes of this Article.
