About Tajima LLP

A boutique litigation firm built for businesses, business owners, and executives — as well as individuals, trusts, and organizations — who need more than just legal advice. They need results.

Chase Tajima
Our Story

Built for Complex Disputes

Tajima LLP (formerly Trepanier Tajima LLP) was founded to bring together skilled litigators trained at leading law schools — including Georgetown, Cornell, UCLA, USC, USD, Loyola Law, and the University of North Carolina School of Law — and experienced at leading national firms. We built this firm to offer the sophistication of a large firm with the agility and personal attention of a boutique — and at rates that are substantially lower than what large firms charge.

Clients choose us because of our track record. Whether we are securing multi-million dollar arbitration awards for plaintiffs or winning defense verdicts in federal court, our focus is always on achieving the best possible outcome for the people and businesses we represent.

We handle complex civil disputes throughout California. Many are entirely domestic; others involve Asia-Pacific parties, ownership, transactions, evidence, witnesses, infrastructure, or assets. In those matters, our role is California litigation and related commercial arbitration, with qualified counsel engaged when separate advice or proceedings are required in another jurisdiction.

Clients seek out Tajima LLP when they need a highly strategic, aggressive litigation firm capable of handling complex partnership disputes, real estate conflicts, and corporate litigation. We have gone up against some of the largest and most formidable law firms in the world — and prevailed — at a fraction of our opponents' cost. Our edge is not size but precision: a lean, focused team that moves faster, thinks more creatively, and leverages cutting-edge technology to outmaneuver opponents burdened by layers of bureaucracy and bloated staffing. Whether navigating a complex trial in Orange County or resolving a high-value breach of contract dispute in Los Angeles, our focus remains singular: maximizing leverage and delivering decisive results for our clients.

Built for High-Stakes Business Disputes

A Smarter Alternative to Big Law Firms

Tajima LLP has represented clients opposite leading national and global Big Law firms in complex litigation, arbitration, transactions, discovery disputes, and contested third-party proceedings. Litigation budgets often play a decisive role in achieving a successful resolution and preserving its financial value. Our focused staffing and direct senior-attorney attention help clients sustain the resources needed to pursue their objectives. This approach can make sophisticated representation and a favorable resolution financially achievable where a larger firm's cost structure would make the same pursuit impractical.

Complex Disputes: $300,000 to $10 Million and Beyond

Tajima LLP is best suited to complex business and civil disputes in Los Angeles and throughout California where approximately $300,000 to $10 million is at stake for either side. We also consider matters involving severe reputational or emotional harm when the stakes justify time and resources comparable to disputes within that financial range.

The $10 million figure is not an upper limit. We also handle disputes involving substantially larger amounts when the cost efficiencies of a boutique law firm and the fit between the matter and our team are especially compelling.

Our approach is designed for matters of this scale and significance. Cases with smaller amounts in controversy—the value of the case to either party—may be better served by a firm whose approach and fee structure are suited to smaller matters.

Litigation is stressful enough without being kept in the dark. We speak plainly, give honest assessments, and keep you informed at every step of the process.

06
Precision Over Size

We have gone up against some of the largest and most formidable law firms in the world — and prevailed — at a fraction of our opponents' cost. Our edge is agility, preparation, and relentless advocacy, not headcount or overhead.
