My document type is not listed. Can you still help?

Usually yes. Send the document and the instruction from the authority that requested it. The chain of certification depends on who issued the document and who will receive it, not on a fixed catalogue, so unusual documents are assessed individually before a plan and a fee are proposed.

Do you handle electronic documents and e-signatures?

Where the receiving authority accepts them, yes. Thailand recognises electronic signatures under its electronic transactions legislation, but many foreign registries and embassies still require a wet-ink original with physical seals. The accepted format should be confirmed in writing before work begins.

What if the destination changes its requirements mid-process?

We re-check requirements close to the filing date for exactly that reason, and if they change we set out the revised steps and any additional cost before continuing. Documents already certified can often be reused in the new chain, which limits the impact.

FAQ

What language for the consent letter?

Bilingual (Thai + destination language) is safest; the notary can attest both.

If custody is sole after divorce?

Attach the divorce decree showing custody; it also needs Apostille.

How long is consent valid?

Usually 3 months; strict jurisdictions (US, Australia) prefer 30 days.
