About Tristan
Biography
Our practice takes family law cases, including surrogacy, dissolutions, parentage, prenuptial agreements, cohabitation agreements, domestic violence, and guardianship cases in Ventura County and Chatsworth.
Admitted to the California Bar in December 1996, I started as a solo practitioner in Westlake Village. Later, I began enjoying work on key areas of dissolution, custody, parentage plus cohabitation issues, prenuptial contracts, surrogacy, adoptions and division of retirement plans. I moved to the office I have now in Thousand Oaks (Newbury Park) in 2005.
I was raised by divorced parents and have been my own client in a divorce case. I realize why clients become depressed and arrive at the court with devotional books and best friends. I share my children with my former wife on a weekly rotational basis.
Fighting in court (litigation) is not necessary, although I do litigation (this is often unavoidable, especially in custody cases). Lawyers are also able to provide 'limited scope' services. In recent years I have built a considerable practice doing mediation and keeping clients out of the courthouse.
New clients are entitled to a free initial consultation. We accept credit cards. Virtually every family lawyer asks for an advance payment, commonly (and incorrectly) called a 'retainer.' I like, virtually all family lawyers charge hourly, although, on rare occasions, I have charged a flat rate for a case. My hourly rate is $375.

Love him
Tristan is an amazing lawyer! He always responds immediately and is very professional. I couldn't have gone through this ugly process without him. He's been practicing family law for 21 years and I HIGHLY recommend him.

Effeciency with morals
Unfortunately Tristan was not my first family law attorney. I wished he was. He is knowledgeable, fair and reasonably priced. His primary focus is doing the right thing. One of the few attorneys I have met that has morals and standards.

Throughout, he's been calm and thorough. The best part is that my X likes him every bit as much as I do, trusting him to give the...
