Parental authority over a legitimate child is exercised jointly by both parents. For an illegitimate child, however, the rule is different: the illegitimate child is under the parental authority of the mother, who exercises it alone, regardless of whether the father has recognized the child. This is because the law considers the mother's care as being in the best interest of an illegitimate child. If the mother is absent or dead, and she has not designated a guardian, substitute parental authority is exercised in the order the law provides (such as the surviving grandparent, then the eldest sibling over 21, then the child's actual custodian, subject to the court's determination of the child's best interest). The recognized illegitimate father, while generally not having parental authority, still has the obligation to support the child, and may be granted visitation rights, and could seek custody only in exceptional circumstances where the mother is shown to be unfit. As to the surname, an illegitimate child generally uses the mother's surname, but may use the father's surname if the father has recognized the child, under the conditions of the law (RA 9255). So the mother's sole authority is the default for illegitimate children, balanced by the father's duty of support.
The Mother's Sole Authority
An illegitimate child is under the parental authority of the mother, who exercises it alone, whether or not the father recognized the child — considered to be in the child's best interest.
Substitute Authority
If the mother is absent or dead (and named no guardian), substitute parental authority follows the legal order — the surviving grandparent, then the eldest sibling over 21, then the actual custodian — subject to the child's best interest.
The Father's Role
The recognized illegitimate father generally has no parental authority but must support the child, may get visitation, and could seek custody only if the mother is unfit. The child uses the mother's surname, or the father's if recognized (RA 9255).
Practical Takeaways
- The mother has sole authority over an illegitimate child;
- The father still owes support and may get visitation;
- Surname is the mother's, or the father's if recognized under RA 9255.
