Brian G. Seastrom is President of Seastrom Tuttle Murphy Dockstader, in Orange County California. He handles complex property division in divorce cases for business owners, executives, and high-net-worth individuals across California.
Super Lawyers has ranked Brian in the Top 5 for Family Law across all of Southern California in 2026, out of more than 10,000 practicing family law attorneys from Santa Barbara to San Diego. Best Lawyers has named him "Lawyer of the Year" twice, in Family Law for Orange County in 2027 and in Family Law Mediation for Orange County in 2026, an honor awarded to one attorney per metro per specialty per year. He is a Fellow of the American Academy of Matrimonial Lawyers and a Fellow of the International Academy of Family Lawyers. He holds the California Certified Family Law Specialist designation, an AAML Certified Family Law Mediator credential, Lawdragon 500 recognition, Doyle's Guide Preeminent status, and an AV Preeminent rating from Martindale-Hubbell.
Brian's litigation practice covers divorces with sophisticated financial architecture: multi-entity business structures, contested business valuations, real estate portfolios with 1031 exchange chains, carried interest and waterfall distributions, RSUs and deferred compensation, goodwill allocations, professional practices, and executive packages.
He also represents physicians and medical practice owners in divorces that turn on what the practice is worth, including its goodwill, and on interests in professional medical corporations and physician-owned surgery centers. Executives and other high-profile clients come to him when a divorce has to be handled discreetly. He keeps as much of their financial and business information out of the public court file as the case allows, using confidential mediation, private judging and protective orders.
His mediation practice brings the same financial depth to settlement design. He builds settlements that use the full toolkit: deferred equalization notes, tax-optimized allocations across real estate portfolios, and creative provisions that protect both sides. For business owners, mediation with Brian means privacy, speed, and deal structures that keep the business running.
Beyond private practice, Brian served as a Commissioner on the California Judicial Nominee Evaluation Commission from 2019 to 2022, chaired the State Bar of California's Family Law Advisory Commission in 2017, and served as President of the Orange County Bar Association's Family Law Section. He has a published appellate decision, In re Marriage of Drake (2015).
Brian represents clients in Orange County, and mediates statewide, including matters with international dimensions through his IAFL fellowship.

Great Attorney!
For me, divorce was an unfortunate necessity to protect myself, my child and my future. It was not to be treated as a competition for financial gain or an opportunity to punish the other party. I expected my actions and the actions of my attorney to be fair, equitable in the division of assets and ...
