Supporting information

Special cases

If someone isn't legally recognized as a parent

Sometimes a parent or guardian is not recognized by law as their child's legal caregiver.

This can affect whether you can get child support and other benefits, as well as custody and visitation rights.

There's a free way to get legally recognized. See how to get recognized as a legal parent.
