Brian D. Mullen, CFLS

Partner

A native of Orange County, Brian has exclusively practiced family law since 2007 to advocate for those experiencing some of the most emotionally exhausting times in their lives.

Brian has been a San Diego divorce attorney and a Certified Family Law Specialist since 2018 by the State Bar of California and was recertified in 2024. He is recognized by his fellow family law attorneys in the 2026 edition of the Best Lawyers in America for his high caliber work in family law.

Over the past several years Brian has litigated many complex child custody cases. For example, in July 2024, over the strenuous objection of the other party and his attorney, Brian’s client prevailed at trial in her request to relocate her children from Orange County to Germany.

Brian has also handled many complex marital and financial issues involving high net worth clients, including actions involving custody, enforcement of family law money judgments and orders, attorneys’ fees & costs, business valuations, and cash flow or income available for support. In fact, Brian convinced a very long-tenured family law jurist to appoint a receiver to collect his client’s spousal support. The judge remarked that it was the first time he had ever appointed a receiver.

Brian routinely handles matters with expert witnesses, including forensic accountants, vocational evaluators, child custody evaluators or Evidence Code section 730 experts, and appraisers. Brian handles family law appeals statewide and has argued before the California Court of Appeal in family law matters.

Brian manages the Orange County division of Wilkinson & Finkbeiner, LLP.

Outside of the office, Brian enjoys golf, travel and is a passionate fan of the Angels, Dodgers, Rams, Packers, Lakers and LA Kings.
