RS 46.2 - Change of maternal filiation; child with unidentified mother  A. Following a final and definitive judgment of maternal filiation, rendered pursuant to Civil Code Article 184, the effect of which is to recognize maternal filiation between a woman and a child whose birth certificate did not identify the mother of the child, the state registrar, upon receipt of a certified copy of that judgment, shall amend the birth certificate as follows:  (1) For the surname of the child:  (a) If the adjudged mother was married to a man at the time of the birth of the child, but was not married to another man within three hundred days prior to the birth of the child, enter the surname of her husband.  (b) If the adjudged mother was not married to a man at the time of the birth of the child, but was married to a man within three hundred days prior to the birth of the child, enter the surname of her former husband.  (c) If the adjudged mother was married to one man at the time of the birth of the child, but was married to another man within three hundred days prior to the birth of the child, enter the surname of the latter.  (d) If the adjudged mother was married neither at nor within three hundred days prior to the birth of the child, enter her maiden name or surname, at her discretion.  (2) For the name of the mother of the child, her date of birth, race, ethnicity, residence, birthplace, and social security number, the number of children born to her, and the number of children born to her living, enter those of the adjudged mother.  (3) For the name of the father of the child, his age, race, ethnicity, and residence, birthplace, and social security number:  (a) If the adjudged mother was married to a man at the time of the birth of the child, but was not married to another man within three hundred days prior to the birth of the child, enter those of her husband.  (b) If the adjudged mother, though unmarried at the time of the birth of the child, was married to a man within three hundred days prior to the birth of the child, enter those of her former husband.  (c) If the adjudged mother was married to one man at the time of the birth of the child, but was married to another man within three hundred days prior to the birth of the child, enter those of the latter.  B. In any case to which the provisions of Paragraph (A)(1) of this Section apply, if the man whose surname should be given to the child and the adjudged mother agree that the surname of the child should be either the maiden name or surname of the mother or a combination of his surname and her maiden name or surname, the state registrar shall enter the surname upon which they have agreed.  C. Upon the petition of the mother of the child, a court may, for good cause shown, order the state registrar to enter, as the surname of the child, the maiden name or surname of the mother or a combination of the surname of the man whose surname should otherwise be given to the child under Paragraph (A)(1) of this Section and the maiden name or surname of the mother, whichever she may choose, even if that man does not concur.
