Are children considered illegitimate after an annulment?

No. In virtually every state, children born during a marriage that is later annulled are treated as legitimate. Modern law protects children from any legal disadvantage based on their parents' marital status.

Do I still have to pay child support after an annulment?

Yes. Child support obligations are based on parenthood, not on the validity of the marriage. Courts order support in annulment cases the same way they do in divorce cases.

How is custody decided in an annulment case?

Courts apply the same best-interests-of-the-child standard used in divorce. Factors typically include each parent's caregiving role, the child's stability, and the child's relationship with each parent.

Does an annulment change who the legal father is?

Generally no. A husband is typically presumed to be the father of children born during the marriage, and that presumption usually survives an annulment. Paternity can be confirmed through testing if it is ever disputed.

Getting an Annulment When You Have Children

By The Annulment Lawyers Editorial Team · 2026-07-19

If you are considering an annulment and you have children, you may be carrying a fear that many parents share: that erasing the marriage will somehow erase your children's legal protections, their legitimacy, or their right to support. Here is the reassuring truth - it will not. Courts treat the marriage and the children as two entirely separate questions, and the law goes out of its way to protect kids when a marriage is declared void.

The Marriage May Be Void, but the Children Are Not Affected

An annulment is a court declaration that a marriage was never legally valid. That sounds sweeping, but its reach is limited to the marital relationship itself. It does not undo anything else that happened during the relationship, and it certainly does not undo parenthood.

In earlier eras, children of an annulled marriage could face harsh legal consequences related to legitimacy. That is no longer how the law works. Today, statutes in virtually every state expressly provide that children born during a marriage that is later annulled remain legitimate. Many states have also abolished legal distinctions based on legitimacy altogether, so a child's rights to inheritance, support, benefits, and a legal relationship with both parents do not depend on whether the parents' marriage was valid.

Put simply: your children keep every legal protection they had before the annulment.

Custody and Parenting Time Work the Same as in Divorce

When a couple with children seeks an annulment, the court does not simply void the marriage and walk away. Courts in annulment cases typically have the same authority they have in divorce cases to decide custody, visitation, and parenting schedules.

The standard is the same one used everywhere in family law: the best interests of the child. Judges commonly look at factors such as:

Each parent's history of caregiving and involvement
The child's need for stability in home, school, and community
Each parent's ability to provide a safe environment
The child's relationship with each parent, and sometimes the child's own preferences depending on age

The reason the marriage is being annulled - fraud, bigamy, underage marriage, or anything else - generally does not determine who gets custody. A parent whose conduct caused the annulment is still a parent, and the court evaluates parenting ability on its own terms.

Child Support Does Not Disappear With the Marriage

Child support is owed by parents to their children. It is not a benefit of marriage, so it does not vanish when a marriage is declared invalid. Courts in annulment proceedings order child support using the same guidelines applied in divorce cases, typically based on both parents' incomes and the amount of time the child spends with each parent.

This cuts both ways, and both directions are protective of the child. A parent cannot escape support obligations by arguing the marriage never legally existed, and a custodial parent does not lose the right to seek support just because the marriage was voided.

Paternity Is Usually Presumed and Usually Survives

Many parents worry that annulment reopens the question of who the legal father is. In most situations it does not. The law in many states presumes that a husband is the father of children born during the marriage, and that presumption typically continues to apply even after the marriage is annulled.

If paternity is genuinely disputed, courts can order genetic testing and establish parentage formally, just as they would for unmarried parents. Once parentage is established, all the usual rights and duties follow: custody, parenting time, support, and inheritance.

What This Means Practically

If you are weighing annulment against divorce and children are part of the picture, it may help to know that the outcome for your kids is essentially the same under either path. Both proceedings can produce enforceable custody orders, parenting plans, and support obligations. The difference between annulment and divorce is about the legal status of the marriage, not the legal status of your children.

That said, annulment cases can involve extra steps, such as proving the grounds for annulment, and property division rules sometimes differ from divorce. Because the details vary from state to state, many parents find it worthwhile to speak with a local family law attorney before choosing which route to pursue.

The Bottom Line

Your children's legitimacy, their right to support, and their relationship with both parents are protected regardless of what happens to the marriage. Courts separate the question "was this marriage valid?" from the question "what do these children need?" - and the second question is always answered with the children's best interests in mind.
