Our Story
A Practice Built Around the People We Serve
Sai Yai Law was founded on a simple belief: that legal support during personal matters should be human, patient, and kind.
← Back to HomeWho We Are
Sai Yai Law
Sai Yai Law was established in Bangkok by a small group of practitioners who felt that family law deserved a different kind of attention. The name — meaning "soft thread" in Thai — reflects our philosophy: that the connections within a family are delicate, and any legal work touching those connections must be handled with care.
Our practice focuses solely on family matters — not because we lack range, but because we believe depth of focus leads to better service. We understand the emotional weight that sits behind every case, and we bring both legal knowledge and personal sensitivity to each conversation.
From an initial private conversation through to formal representation in proceedings, clients work with practitioners who know their situation, remember their concerns, and keep them informed every step of the way.
Our Mission
To provide family law support in Bangkok that is as considerate as it is capable — always placing the client's wellbeing at the centre of our work.
Our Vision
A practice where every person who walks through our door — or calls us for the first time — feels heard, respected, and well-supported through whatever they face.
Our Values
Confidentiality, honesty, patience, and respect. We do not rush, we do not pressure, and we do not speak in ways that confuse or intimidate.

How We Work
Professional Standards We Uphold

Client Confidentiality
We strictly observe professional confidentiality obligations. Nothing you share is disclosed without your explicit consent, and all records are held securely.

English & Thai Services
We work fluently in both English and Thai, supporting expatriate and international clients alongside Thai nationals with equal care and clarity.
Family Law Expertise in Bangkok
Sai Yai Law operates from the heart of Bangkok's Pathum Wan district, serving clients across the city and the wider Bangkok metropolitan area. Our focus on family law means we bring deep familiarity with the Thai Civil and Commercial Code as it applies to family relationships, parental responsibilities, and formal proceedings before the Thai family courts.
We assist clients at every stage — whether they are seeking a first private conversation to understand their position, looking for help reaching a fair parenting agreement, or in need of considered representation during formal family proceedings. Each path is approached with the same standard of care and the same respect for the client's circumstances.
Working with both Thai nationals and international clients — including expatriates and those in cross-border family situations — we bring cultural sensitivity and legal knowledge together. Our clients often tell us that what they valued most was feeling heard, not hurried, and informed throughout. That is the standard we hold ourselves to every day.
