  The usual causes of rejection are name spellings that differ between documents, documents that expire before the filing date, uncertified copies, and translations that do not match the original. the courts and the relevant Land Office returns files for exactly these reasons, so we cross-check names, dates and seals across every page before submitting foreign probate.

  The framework is set by Book VI of the Civil and Commercial Code and the Inheritance Tax Act B.E. 2558, together with the regulations and notifications issued by the courts and the relevant Land Office, which are revised from time to time. Before advising on foreign probate we verify the version in force on the filing date and rely on official sources rather than second-hand summaries.

  First we obtain the written reason from the courts and the relevant Land Office, then separate formal defects (fixable and quickly refiled) from substantive or eligibility issues (which need a change of approach).

We screen eligibility free of charge before accepting the case.

  Certified documents rarely carry an expiry date themselves, but most receiving authorities require issuance within 3–6 months of submission, and some are stricter.

• Q966086. Does foreign probate also need an English or target-language translation?
