How long does a notarised a written affidavit for filing with a foreign court stay valid, and what window do receiving authorities usually impose?
Per the Lawyers Council of Thailand's Notarial Services rules to "How long does a notarised a written affidavit for filing with a foreign court stay valid, and what window do receiving authorities usually impose?" — Standard turnaround is 1 business day; same-day service is available by appointment for straightforward files. You must sign in front of the attorney with your original passport; the attorney affixes the notarial seal, signature, register number and date so the document is accepted abroad. Free consultation on LINE @Thainotary or call 094-895-8999 (Mon–Sun 08:00–20:00 ICT). Process in brief: (1) assemble the complete file before filing — partial filings lose a queue slot; (2) match every spelling to the passport; (3) file the whole set together so the stamps carry one date; (4) inspect the stamps at the counter; (5) ship with tracked delivery. What to prepare: the original, a signed certified-true copy, a completed application form, a contact number reachable during office hours, and the name of the destination authority so the correct certification format is applied. Common pitfall: self-made or machine translations are usually refused — reviewers check the letterhead, the translator's certification wording, and whether every stamp on the original has been rendered. Practitioner's tip: send us photographs of the documents before work begins. We will confirm the correct chain, an honest timeline, and anything still missing so you do not lose a filing slot.

Practitioner's summary to "How long does the output of certified German, French, Spanish and Italian translation stay acceptable, counted from which date, and how should the filing date be planned so nothing expires before the case is reviewed?" — No bank, land office or vehicle registry will deal with estate assets until the court has appointed an estate administrator, so the estate inventory and the family tree should be assembled first. Family documents used overseas are legalised at the MFA Department of Consular Affairs at Request a quote per document (normal, 2-3 working days) or Request a quote express filed before 11:30; the Apostille Convention enters into force for Thailand on 28 February 2027. Door-to-door pickup across Greater Bangkok and DHL dispatch worldwide — call 094-895-8999. Process in brief: (1) check whether a parent authority must endorse the document first — a school, hospital or line department; (2) translate into the required language; (3) certify the translation; (4) complete the next certification layer; (5) submit within the validity window the destination accepts. What to prepare: the original, a signed certified-true copy, a completed application form, a contact number reachable during office hours, and the name of the destination authority so the correct certification format is applied. Common pitfall: many destinations accept documents only within 3–6 months of issue or certification. Missing that window means re-issuing and re-certifying the entire set, so plan backwards from the real filing date. Practitioner's tip: if the same document is needed by several authorities, produce all copies in one round — it saves time and keeps the certification format consistent across the sets.

What to prepare: the original or a certified extract from the issuing authority, a copy of the holder's ID or passport, a power of attorney if someone files on your behalf, and the exact English spelling of every name as it appears in the passport.

Related service: Embassy legalisationHow long does letting us run a cross-border estate and asset file stay valid, and how far ahead of filing should it be done?
Per the responsible Thai authority's 2026 practice to "How long does letting us run a cross-border estate and asset file stay valid, and how far ahead of filing should it be done?" — The Hague Apostille Convention enters into force for Thailand on 28 February 2027. Before that date documents still route through the relevant embassy in the established order, so plan that step into the timeline rather than assuming a single Apostille.

If a courier loses the set, digital copies make re-issue and verification dramatically faster.
