5 common mistakes with Adoption Certificate — and how to avoid them
Across more than 12,000 NAATI translations we've seen the same five mistakes again and again with Adoption Certificate submissions. Avoid them and you'll usually pass on the first attempt.
1. Submitting expired evidence (police clearance and medical certificates expire after 12 months)
2. Using a self-translation or non-NAATI translator — DHA and AHPRA reject these immediately and request a re-submission
3. Incomplete scans of the source document (missing back pages, stamps, or signatures), forcing a redo of the work
4. Inconsistent name spellings across documents (passport vs. birth certificate) — usually requires an additional Statutory Declaration
5. Mistranslating Thai government terminology (e.g., translating 'Amphoe' as 'District', confusing it with Bangkok districts)
NAATI Thailand runs a two-stage QC (translator → reviewer → final stamp). Our first-time approval rate is above

Skilled / PR bundle (subclass 189/190): Adoption Certificate + Police Clearance (PCC) + Bank Statement + Employment Letter + Degree + Transcript. We archive the full bundle so you can re-download for up to 5 years.
Partner Visa bundle (subclass 820/801, 309/100): Adoption Certificate + Marriage Certificate + Statutory Declaration + ID Card + House Registration. We can liaise directly with your migration agent or solicitor.
Citizenship by Descent bundle: Adoption Certificate + child's birth certificate + parents' passports + parents' marriage certificate. Bundling typically saves THB 2,500-4,000 versus ordering separately.
