FMBK

What FMBK does

FMBK Law, LLP (Feinberg, Mindel, Brandt & Klein, LLP) is a Southern California limited liability partnership founded in 1990 by Steven A. Mindel and Irwin B. Feinberg, specializing in family law, estate planning, and probate and trust litigation. The firm operates from three California offices — West Los Angeles (headquarters at 12424 Wilshire Blvd., 9th Floor), Pasadena, and Calabasas — and employs 25 attorneys, of whom 21 practice exclusively family law, 12 are partners, and 12 hold the Certified Family Law Specialist (CFLS) designation, which the firm characterizes as the highest concentration of CFLS attorneys in the region. Practice areas cover dissolution of marriage, child custody and visitation, child and spousal support, division of assets and debts, prenuptial and postnuptial agreements, domestic violence, paternity, and the cross-over of family law with estate planning, wills, trusts, powers of attorney, conservatorships, and contested probate matters.

The firm's business model is professional-services fee-for-service billing on hourly, fixed-fee, or project arrangements, with rates that vary by attorney seniority (partners and CFLS commanding premium rates) and matter complexity. FMBK's go-to-market is sales-led and relies on direct client acquisition through Initial Client Consultations, a professional referral network of attorneys, financial advisors, and mental-health professionals, and inbound inquiries generated by extensive media coverage in outlets such as People Magazine, Good Morning America, Entertainment Tonight, The Atlantic, NBC News, and KTLA. The firm targets high-net-worth individuals, entertainment industry professionals, business owners and executives, and estate planning clients. Revenue figures are not publicly disclosed.

The firm has no proprietary technology platform; operations are delivered through attorney-led matter teams with administrative support, a proprietary internal training curriculum ("FMBK University"), and a 30+ year Summer Associate Program that operates as a homegrown talent pipeline converting summer associates into associates and, in some cases, partners (e.g., Gregory Girvan joined via the 2009 Summer Associate Program). Growth has come via organic partner promotions, lateral hires, and a 2021 merger with Thomas L. Simpson's Simpson Law Group, which brought the firm above 20 attorneys. FMBK is privately held with no external investors, parent company, or subsidiaries.
