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 child and a woman other than the woman identified in the birth certificate as 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) Strikethroughs:

            (a) Strike through the surname of the child, the name of the mother of the child, and all other information pertaining to the mother, in particular, 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.

            (b) If the name of the father of the child or other information pertaining to him, in particular, his age, race, ethnicity, residence, birthplace, and social security number, as it was previously entered on the birth certificate, was that of the man who, by virtue of his marriage to the woman previously identified in the birth certificate as the mother of the child, was presumed to be the father of the child under Civil Code Article 185 or 186, the state registrar shall strike through his name and his other information.

            (2) Additions:

            (a) For the surname of the child:

            (i) 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.

            (ii) 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 the surname of her former husband.

            (iii) 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.

            (iv) 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.

            (b) 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.

            (c) For the name of the father of the child, his age, race, ethnicity, residence, birthplace, and social security number:

            (i) 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.

            (ii) 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.

            (iii) 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)(2) 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, the surname of the man, 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)(2) of this Section and the maiden name or surname of the mother, whichever she may choose, even if that man does not concur.
