In a dispute to rename a child of divorced parents, the party seeking to alter the surname jointly given to the child at birth bears the burden of proving by a preponderance of the evidence that the change is in the child’s best interest. Irrespective of whether the parents were married at the time of the child’s birth, the best-interests-of-the-child test should be applied in a renaming dispute without a presumption in favor of the custodial parent’s decision to change the jointly given surname of the child. 8-12-13
