A declaration or certificate of heirship — what should you know about naati-related requirements?

The issue to settle here is “A declaration or certificate of heirship”, so the answer below starts with what this case actually needs before setting out the general rules. The specifics here are document type: Heirdeclare, and those decide which translation and certification level applies. The terms that frame this page are declaration · certificate · heirship · know. The deciding factor is the receiving body's requirement, not only the format of the Thai-side document. What sets this case apart is the number of certified sets and the window in which they must be used. Before starting, confirm with the receiving body whether it wants an original, a certified copy or a certified translation, then check that names are spelled identically to the passport or ID card on every page, then verify the source document is still within any validity window the recipient applies. If multiple certified sets are needed, order them all in the first round to avoid re-queuing. For documents going abroad, include international shipping time in the plan. Attach a document index to the bundle so nothing is lost during review. Keep a copy of every source document plus the receipt or docket from each step. The deceased's and heirs' names must be spelled identically throughout; if not, add evidence they are the same person. Run the Thai and overseas document tracks in parallel, since their timelines differ. The next step is confirming the filing channel and the copy or file format required. Australian bodies — courts, insurers, superannuation funds and government agencies — require non-English documents to carry a translation by a NAATI-certified translator, with the stamp, practitioner number and certification expiry legible. Where the receiving body also asks for the certified source document, keep the translation and its source attached as a single set exactly as instructed. A cross-border claim bundle typically requested by insurers and pension or superannuation funds includes the policy or certificate of cover, the claim form, the death certificate or medical certificate, an autopsy report or police daily record where an accident is involved, itemised medical invoices and discharge summaries, proof of the beneficiary's relationship and bank details for payment. Every Thai-language document must be translated and certified as the receiving side requires. ILC handles documents only — translation, certified translation, arranging notarial-attorney certification and running legalisation at the Department of Consular Affairs and embassies. It is not a law firm, does not draft wills as legal counsel, does not act as estate administrator, does not pursue claims on a policyholder's behalf and guarantees no decision by any court, registrar or insurer. Cost and lead time depend on page count, target language, how many certified sets are needed and the steps the receiving authority requires, so every file is quoted before work starts.
