La. Civ. Code art. 196
Current with operative changes from the 2024 Third Special Legislative Session
A man may, by authentic act, acknowledge a child not filiated to another man. The acknowledgment creates a presumption that the man who acknowledges the child is the father. The presumption can be invoked only on behalf of the child. Except as otherwise provided in custody, visitation, and child support cases, the acknowledgment does not create a presumption in favor of the man who acknowledges the child.
