Why families choose us

Working with Sai Yai Law

Clear, written communication

Every significant step produces a written note. Families keep a record they can read at their own pace, not only during appointments.

An unhurried approach

Family law matters benefit from patience. We do not press families toward decisions before they are ready, and we explain each stage before it begins.

Thailand and cross-border experience

Sai Yai Law is based in Bangkok and familiar with matters that move between Thai courts and authority systems elsewhere in the region and beyond.

Organised documentary record

We maintain a structured file throughout any matter. Families can request their record at any point, and it will be complete and legible.

Sensitive handling of personal matters

Adoption, guardianship, and separation each carry weight beyond the paperwork. We handle the legal side carefully, without treating difficult circumstances as routine.

Transparent, stated fees

Each service carries a stated fee published in advance. There are no undisclosed additions. Families know the cost of each piece of work before it begins.

Would a conversation help clarify where things stand?

Send us a brief note about your matter. We will read it carefully and respond with a plain account of what the next step might involve.

Common questions

Questions families often ask

What documents are typically needed for an adoption review?

The documents vary by family circumstance, but generally include household registration records, the consent forms of relevant parties, any prior social worker or welfare reports, and identification for each person involved. Our review covers what you have already gathered and notes what may need to be supplemented before the application is submitted.

How long does a guardianship application typically take?

The timeline depends on the authority handling the matter and whether an independent assessment is ordered. Many applications are reviewed within two to four months of submission, though more complex family situations can take longer. We report on progress in writing at each meaningful point so you are not left waiting without information.

Our family situation involves two countries. Can Sai Yai Law help?

Yes. International family coordination is one of our core services. We review the applicable framework in each country involved, identify any relevant coordination provisions, draft correspondence with each authority, and reconcile the responses we receive into a single, readable record for your family. We handle English-language correspondence across jurisdictions as part of the service.

Are the service fees fixed, or do they change as the matter progresses?

Each service has a stated fee that covers the scope of work described. If a matter develops in a way that falls outside the original scope — which we would identify and explain to you in writing — we would agree a separate fee with you before proceeding further. There are no undisclosed additions within the agreed scope.

How is my family's information handled and kept private?

Information shared with Sai Yai Law is kept confidential and used solely to carry out the work you have engaged us for. We do not share details with third parties except where required by the matter — for example, communicating with a government authority on your behalf. Our full approach is set out in our Privacy Policy.

How do I begin — do I need to gather documents before contacting you?

You do not need to have anything ready before reaching out. Send us a brief note about your situation using the form below, or call during office hours. We will reply with a clear account of what would be involved, and you can take as much time as you need before deciding how to proceed.
