Last Updated: July 2026

If you live in Sonoma County and need a family law attorney who knows the local courts, Castro Law Offices is ready to help. Jeremy Castro and our North Bay team regularly represent families in Petaluma, Santa Rosa, Windsor, Healdsburg, Rohnert Park, and surrounding communities before the Superior Court of California, County of Sonoma.

Jeremy earned his undergraduate and law degrees at Golden Gate University and focuses on practical guidance through divorce, custody, support, adoption, paternity, and domestic violence restraining order matters.

Call (415) 432-9866 or request a consultation below. You can also review our county overview on this page and our related Sonoma practice pages for divorce, custody, and adoption.

Adoption Lawyer Sonoma County

When you decide to adopt, getting the paperwork and court process right the first time matters. A Sonoma County adoption attorney can explain California adoption options – stepparent, independent, and adult adoption – and help you prepare petitions, consents, and hearing requirements.

Castro Law Offices assists Sonoma County families with adoption matters and maintains a local page for an adoption lawyer in Sonoma. We help reduce stress by organizing the timeline, filings, and next steps so you can focus on your family.

Child Custody Lawyer Sonoma County

Child custody is often one of the most important issues in a Sonoma County family case. California looks at the best interests of the child, including legal custody (decision-making) and physical custody (where the child lives), plus visitation schedules that work in real life.

Jeremy Castro helps parents negotiate parenting plans when possible and advocates in court when needed. Learn more about child custody, custody modification, and our Sonoma County child custody page.

Child Support Lawyer Sonoma County

California guideline support under Family Code section 4053 applies in Sonoma County, but accurate income, timeshare, and add-ons such as childcare and health insurance still drive the result. Whether you need to establish support, modify an order after a job change, or enforce unpaid support, clear financial disclosures matter.

Our team helps Sonoma County parents through child support and support modifications with practical next steps for court or negotiation.

Divorce Attorney Sonoma County

Filing for divorce is a major life decision. California is a no-fault state, but temporary orders, property division, parenting plans, and support still require careful planning – plus the mandatory six-month waiting period after service.

Castro Law Offices guides Sonoma County clients through filing, disclosure, negotiation, and hearings. Explore our divorce practice and our Sonoma County divorce page, then call or request a consultation when you are ready to talk.

Domestic Violence Restraining Order Lawyer Sonoma County

If you need protection – or have been served with a restraining order – deadlines move quickly. In California, a Domestic Violence Restraining Order can be based on abuse or threats involving an intimate partner or certain relatives; physical injury is not always required.

We help Sonoma County clients prepare declarations, gather evidence, and present a clear case at the hearing. Learn more about our domestic violence restraining order services.

Paternity Lawyer Sonoma County

Establishing parentage identifies a child’s legal parents and unlocks custody, visitation, and child support rights and responsibilities. California offers several paths, including court judgments and, in some situations, Voluntary Declarations of Parentage.

Castro Law helps unmarried parents in Sonoma County through paternity and parentage cases with a clear plan for filings, testing when needed, and court orders.

Spousal Support Lawyer Sonoma County

Spousal support (alimony) can be one of the most contested parts of a divorce. California judges weigh factors such as marriage length, income, earning capacity, and the standard of living during the marriage.

We help Sonoma County clients request, negotiate, or modify spousal support with complete financial disclosures and a strategy tied to your goals.

Jeremy Castro helped me with an adoption after my daughter’s dad passed away. My husband has been a step dad to her for 8 years and wanted to adopt her. Even though there is no way he can completely fill the role of her deceased father, he wanted to fully be there for her and offer comfort and emotional support for her. Jeremy and his wife Danielle were there every step of the way for us! I’m so grateful they were there to help with all of our questions and guide us though this process. Jermey’s passion for helping bring families together was so delightful.

This review is about my experience with Jeremy and team at Castro Law. After calling around numerous times to different firms, going to the law library, and reaching out to dads rights advocates. I still didn’t get much help. I made the best choice of my life by calling Castro Law. If you’re reading this I recommend at least giving them a call because they mean business. I finally feel at peace , they went above and beyond for me. The team is great at communicating, very knowledgeable, helpful, and are professional. In my experience mothers are the one favored in the courts, and get the better outcome. Jeremy and team were in my corner the whole time and proved that dads have rights too! Im with this team until my kids are 18 , thanks again Castro Law

I highly recommend Jeremy Castro and his associates to any future clients. They are legal professionals who: 1. Know and apply the law to your individual case to achieve the best possible outcome 2. Communicate in a fair and straightforward manner to all parties 3. Reduce the tension in an otherwise emotional setting and assist making objective decisions. They personally saw my case through to an amicable conclusion and their billing hours were appropriate. First class performance!

I wanted to take this time to write a review about my experience with Castro Law Offices. First off, they were not only FAST to my reply, but also very kind to my emotional situation. I was even handed some tissues for when I was crying. I was treated with the upmost respect (even though I'm sure I looked a little manic while in there explaining my case.) and kindness. They got my case close within a week, and also got me EVERYTHING I was asked for. I recommend Castro Law for ANYONE in need of lawyer assistance. Jeremy and his team work hard, day and night to make sure they meet all of their client's needs. If you're looking for immediate help and guidance with ANY attorney, Castro Law.

When things came to a point of contention with my children's father I knew I needed the help of an attorney. After weeks long search and hundreds of dollars in consultation fees with numerous other attorneys I finally found Jeremy! He is very knowledgeable regarding family law issues, authentic in his character and legal advice, as well as very reliable. As anyone in our shoes has been knows, the unknown can be very stressful. Jeremy made it a point to get back to me promptly when I contacted him...sometimes late into the night. He also was very transparent regarding communication with the other party. Would absolutely recommend Jeremy to anyone with with family law needs!

I was so happy I had decided to hire the Castro Law Office for my child custody and visitation case in Napa County. As a single father of three boys in the state of California, I felt as if I was already doomed thinking that the state would favor the mother regardless of my capability to care for our children. Jeremy was very empathetic and worked diligently to get myself in a good position for the hearing, as I hired him approximately a month prior to the court date. During the hearing, he was very stern and aggressive at the right moments. The situation I was in was extremely stressful and hiring the Castro Law Office helped put my mind at ease. He was very upfront and honest with me from the beginning and which is a trait I greatly appreciated. In the end, we were able to obtain an agreement that is best suited for the children and ourselves. I would hire them again for any other issues I might have in the future.
