The Data Hook

A large and growing share of children are born to unmarried parents — which means custody and support get decided without a divorce ever being filed. The legal door for both parents is parentage (paternity), and until it's established, the rights are lopsided.

His Side — Michael

An unmarried father often discovers he has few enforceable rights until parentage is legally established — he can be expected to pay support while having no guaranteed custody or visitation. His worry is being treated as a wallet, not a parent. The mistake is assuming his name on the birth certificate, or a good relationship with the mother, is enough; without an order he has little recourse if access is cut off.

Her Side — Ava

An unmarried mother typically has sole custody by default until a court orders otherwise, and she wants support and stability locked in for the child. Her concern is a father who wants rights but not responsibility — or who appears only when convenient. Her mistake is assuming control of access is permanent; once parentage is established, the father has real standing.

The Law (Both Sides)

California parentage can be established by a Voluntary Declaration of Parentage (signed at birth, with the force of a judgment) or by a parentage action under the Uniform Parentage Act, sometimes with genetic testing. Once parentage is established, the same custody, visitation, and guideline-support rules that govern divorcing parents apply — gender-neutral, best-interest-of-the-child. A "presumed parent" status can also arise from receiving the child into the home and holding the child out as one's own.

What to Do
