The general rule is that courts will exercise the power to change a child's name from the father's surname reluctantly and only when the substantial welfare of the child requires it. There is a list of twelve (12) factors the court will typically consider before changing the child's name. These factors include: (1) whether the changed name or the present name would best avoid embarrassment, inconvenience, or confusion for the custodial parent or the child; (2) whether it would be more convenient or easier for the child to have the same name as or a different name from the custodial parent, either the changed name or the present name; (3) whether the changed name or the present name would help identify the child as part of a family unit; (4) the length of time the surname has been used; (5) parental misconduct, such as support or nonsupport or maintaining or failing to maintain contact with the child; (6) the degree of community respect associated with the present or changed name; (7) whether the change will positively or adversely affect the bond between the child and either parent or the parents' families; (8) any delay in requesting or objecting to name change; (9) the preferences of the child; (10) the age and maturity of the child; and (11) when the child maintains the mother's surname, assurances by the mother that she would not change her name if she married or remarried; and (12) whether the parent seeking the change is motivated by an attempt to alienate the child from the other parent.
