Paternity & Parentage

Paternity & Parentage in California: Establishing Rights. Defining Responsibilities.
Legal Guidance to Clarify Parent-Child Relationships and Protect What Matters Most
Establishing parentage (also known as paternity) isn’t always as simple as biology or a birth certificate. In California, the law recognizes multiple pathways to becoming a legal parent—and with that status comes both rights and responsibilities. Whether you’re seeking to confirm parentage, contest it, or assert your parental rights, PLBK Law can help you make the right legal play before time runs out.

When Is Parentage Presumed in California?
A person is presumed to be the legal parent of a child if:
-
The child is born during the marriage between that person and the biological mother, or
-
The child is born within 300 days of the marriage ending (by divorce, annulment, or death)
But marriage is not the only way to establish legal parentage.
Other Legal Paths to Establish Parentage
You may be recognized as a legal parent if:
-
You signed a Voluntary Declaration of Parentage (VDOP) at the hospital or later
-
You are the biological parent and want to establish legal recognition
-
You were an intended parent in an assisted reproduction case
-
You attempted to marry the child’s biological parent before the birth, even if the marriage was invalid
-
You married the biological parent after the child’s birth and were added to the birth certificate or have treated the child as your own
➡️ The law even allows for more than two legal parents, when it serves the child’s best interest.
Voluntary Declaration of Parentage (VDOP): What You Need to Know
A VDOP is a legally binding document that establishes parentage outside of marriage.
Key facts:
-
It can be attached to a court petition to determine parentage
-
If not contested within two years, it carries the same legal weight as a court judgment
-
If you signed one in error or under pressure, seek legal advice immediately—time is critical
Contesting or Asserting Parentage
Whether you believe you’ve been wrongly identified as a parent or are being denied your rightful role in your child’s life, PLBK Law can help you:
-
File or respond to a Petition to Establish Parentage
-
Request or contest custody, visitation, or support orders
-
Present evidence of your role in the child’s life
-
Protect your rights while prioritizing the child’s best interest
Why Establishing Parentage Matters
Establishing legal parentage allows the court to make decisions on:
-
Custody and visitation
-
Child support
-
Inheritance and benefits rights
-
Health insurance and financial responsibilities
It also provides clarity for the child, both emotionally and legally.
Don’t Let the Clock Run Out
In parentage cases, timing is everything. Waiting too long to act can severely limit your options—or lock you into legal responsibilities you may not have anticipated. Whether you’re seeking to establish, challenge, or understand your legal status as a parent, PLBK Law can help you take control of the process with confidence.
