A paternity determination can change many aspects of your life and your child’s life. The father may be granted new rights to child custody or visitation — or the determination of paternity could result in the father becoming responsible for child support. At Haslam Perri Law Firm, our experienced attorneys represent both mothers and fathers in every type of paternity proceeding in San Bernardino County.
Our attorneys understand that each paternity situation is unique. We have significant knowledge of the types of paternity cases our clients face and the most effective ways to reach favorable resolutions — whether that means establishing, contesting, or revoking a paternity determination.
Once paternity is established and confirmed in court, both parents have equal rights to custody, visitation, and child support. Each parent also has the right to participate in decisions about the child’s healthcare, religion, and education. Donald Glen Haslam and our board-certified team protect these rights aggressively.

Frequently Asked Questions
Paternity Law — Questions Answered
Clear answers to the most common paternity questions in San Bernardino County. Whether you are a mother or a father, call us for a free consultation specific to your situation.
In California, paternity can be established in several ways. If both parents are unmarried and agree on paternity, they can sign a Voluntary Declaration of Parentage (VDOP) — a legal document that establishes the father’s parental rights and responsibilities without going to court. If paternity is disputed, either parent can file a paternity action in San Bernardino Superior Court, and the court may order genetic DNA testing to determine biological parentage. At Haslam Perri Law Firm, our attorneys guide both mothers and fathers through every paternity process.
Once paternity is legally established in California, the father has the same parental rights as any married father — including the right to seek legal and physical custody, the right to visitation, and the right to participate in decisions about the child’s healthcare, education, and religious upbringing. Establishing paternity also creates financial obligations, including child support. Our attorneys help fathers assert and protect these rights fully from the moment paternity is confirmed.
Yes, but there are strict time limits. A Voluntary Declaration of Parentage can generally be rescinded within 60 days of signing, or before a court makes an order regarding the child based on the declaration — whichever occurs first. After this window, revoking a VDOP requires filing a court action and showing that the declaration was signed based on fraud, duress, or material mistake of fact. Our attorneys act quickly when clients need to challenge or revoke a paternity declaration.
If you have been incorrectly named as the father of a child — whether on a birth certificate, in a court order, or in a paternity action — you have legal options to challenge this determination. California courts can order genetic DNA testing to establish or disprove biological parentage. Acting quickly is critical, as delays can complicate the legal process and may affect your rights and obligations. Our attorneys represent men contesting false paternity claims throughout San Bernardino County.
Yes. Once paternity is legally established, the father becomes responsible for child support under California law. Child support is calculated using the Dissomaster formula, which takes both parents’ incomes, the amount of time each parent spends with the child, and other financial factors into account. Our attorneys ensure that support calculations are accurate and fair — protecting both the child’s financial interests and the rights of both parents.
Yes. California courts have jurisdiction to establish paternity even when the father lives in another state, as long as the child lives in California or the alleged father has certain connections to California. Interstate paternity cases involve additional legal complexities, including the Uniform Parentage Act and federal child support enforcement laws. Our attorneys at Haslam Perri Law Firm have experience handling cross-state paternity matters throughout San Bernardino County.
