MS SB2262

Amends paternity determination law to allow child's surname to be either agreed upon by unmarried parents or determined by court based on the child's best interests, considering the child's age, length of time using a particular surname, and the child's preference if old enough to express one.

Requires courts determining paternity to also determine the child's surname rather than automatically assigning the father's surname.

Allows unmarried parents to agree on a child's surname in a voluntary acknowledgment of paternity affidavit, with court determination if parents cannot agree on the surname.

Establishes that a voluntary acknowledgment of paternity can be rescinded within one year or before a judicial proceeding involving the signatory, but after one year can only be challenged for fraud, duress, or material mistake of fact.

Takes effect July 1, 2014.
