Single Status Affidavit (Affidavit of Eligibility to Marry) — Notarial Services Attorney · HCCH Apostille (มีผล 28 ก.พ. 2570) · CCC § 1452 Shield
We issue a Single Status / Affidavit of Eligibility to Marry that Thai District Offices actually accept for marriage registration — and that foreign Civil Registries actually accept when a Thai national is marrying abroad. End-to-end scope: embassy affidavit booking, MFA-certified translation, notarization by a Lawyers-Council-registered Notarial Services Attorney under Reg. B.E. 2546, MFA Apostille / Authentication (HCCH entering into force in Thailand on 28 February 2027), and District Office filing under DOPA Reg. B.E. 2541. All nationalities served (US/UK/EU/AU/NZ/JP/KR/CN/IN/ME). We engineer a path that does not breach CCC § 1452 (no bigamy), § 1453 (310-day waiting period for women), or Penal §§ 137/177/264. No outcome guarantee on the foreign registry side — but a 100% refund if any document we produced is rejected because of our error.
A Single Status Affidavit (Affidavit of Eligibility to Marry / Certificate of No Impediment — CNI) is a **mandatory** document for every foreigner registering a marriage under Thai law, whether marrying a Thai national, marrying another foreigner in Thailand, or supporting a Thai partner's overseas marriage. The legal anchor is CCC § 1452 — Thailand enforces strict monogamy, so District Offices and Civil-Law civil registries demand affirmative evidence that you are genuinely single on the registration date, not merely a stale extract from your home country.
The most common — and most expensive — mistakes we see are (a) using an expired Affidavit (most embassies allow 3–6 months; District Offices typically reject anything older than 6 months); (b) using a translator not on the MFA-certified list — the Consular Department refuses to authenticate the file; (c) skipping the MFA step entirely — the District Office will not accept a document straight from an embassy; (d) presenting a home-country affidavit without Apostille from that country; (e) forgetting the 310-day waiting period under § 1453 for recently divorced or widowed women (exceptions exist but must be evidenced); (f) naming a Thai fiancé(e) on the affidavit without lawful consent under PDPA § 26.
Our team consists of Notarial Services Attorneys registered with the Lawyers Council of Thailand (verify at /trust/credentials), partnered with MFA-certified ISO 17100 TEP translators and a dedicated Consular liaison at the MFA Chaeng Watthana office. Scope: (1) pre-check your civil-status record against your country's registry; (2) book your embassy appointment in Bangkok and draft the affidavit; (3) certified translation; (4) attorney notarization with in-person signature under Reg. 2546 §§ 17–19; (5) MFA Apostille or Authentication; (6) accompanied filing at the District Office of your choice; (7) onward translation + Apostille of the resulting Khor.Ror.3 marriage certificate for foreign use. Lawyer-client privilege from your first LINE message, PDPA § 24 + 26 (sensitive data), ISO/IEC 27001 servers in Thailand, AMLA CDD throughout. **No contingency fees** under Lawyers Council Code of Ethics 1986 § 11.
Impact of HCCH Apostille (entering into force in Thailand on 28 February 2027): for the 130 contracting states, a single Apostille replaces embassy legalization, cutting turnaround from 7–14 days to 1–3 business days and dropping costs 60–75%. For non-contracting states (Canada in certain scenarios, several Middle East jurisdictions, with Hong Kong / Macao still under special arrangements even after PRC's Nov-2023 accession), embassy legalization remains required. We verify destination-country status before issuing any quote — no surprise costs.

Workflow verification — what we double-check for you
How long is a Single Status Affidavit valid? How old will a Thai District Office accept?
Most embassy-issued affidavits in Bangkok are valid 6 months; Thai District Offices typically refuse anything older than 6 months from the Consul's signature date. UK CNIs from home Register Offices are valid only 3 months. We plan the marriage date inside this window every time.
How many days in advance should I book my embassy appointment?
US Embassy: 5–10 business days; UK Embassy: 7–14 days; AU/NZ: 3–7 days. EU CNIs from home registries (DE/FR/IT/ES) need a 28-day Posted Notice + 7–14 days mailing + in-country Apostille — start 6–8 weeks ahead.
How is Apostille (HCCH (in force for Thailand 28 February 2027)) different from legalization?
Apostille is a single-layer authentication accepted in 130 contracting states. Since 28 February 2027 Thailand issues Apostille at the MFA Department of Consular Affairs instead of embassy legalization for contracting states (60–75% faster). Non-contracting states (Canada in some scenarios, several ME jurisdictions) still require embassy legalization.
Is the § 1453 310-day waiting period for women always required?
CCC § 1453 imposes it after a prior marriage ends, but exceptions apply: (a) you have already delivered the child, (b) a medical certificate confirms no pregnancy, (c) court permission, or (d) remarriage to the same ex-spouse. We pick the fastest lawful path — never an unlawful workaround.
If I marry abroad, does my marriage automatically count in Thailand?
No. You must recognize it at a Thai District Office by submitting the foreign marriage certificate + Apostille + Thai translation under DOPA Reg. 2541. The amphoe must also verify §§ 1452/1453/1454 — some marriages valid abroad will not be recognized in Thailand.
I hold two passports — which nationality do I use?
Practice at the Department of Provincial Administration is to use the passport that matches your TM.6 / visa stamp. The embassy affidavit must come from that nationality's embassy. Where the alternate citizenship's process is easier, we sometimes switch — but every document then has to match consistently.
Can you handle Phuket / Pattaya / Chiang Mai?
Yes — we have Notarial Services Attorneys in every major tourist province. Travel cost at actual + quote on request (phone / LINE / email)/day attorney time. Recommended amphoes with bilingual officers: Kathu/Thalang (Phuket), Bang Lamung (Chonburi), Mueang Chiang Mai, Hua Hin (Prachuap).
What does the all-in cost actually include? Are there hidden fees?
The written fixed-fee quote covers: (1) embassy fee (2) MFA-certified translation (3) MFA Apostille/Authentication (4) Notarial Attorney fee (5) amphoe fee (statutory free) (6) document courier (7) interpreter on filing day if the non-Thai spouse doesn't speak Thai. No surprises — any scope change is re-quoted in writing.
How is my personal data protected?
Civil status + civil registration records are sensitive personal data under PDPA §§ 24 + 26. Stored on ISO/IEC 27001 servers in Thailand, AES-256 + HSM at rest, TLS 1.3 in transit, MFA + biometric access, full audit logging, 10-year retention (Notarial standard), DPO registered with the PDPC. Subject access: dpo@notary.co.th.
Is the first consult free? What do I send?
Yes — first consult free. LINE us: (1) passport bio page (2) nationality + current status (single/divorced/widowed) (3) destination country for the marriage (4) preferred marriage date (5) province of convenience. Within 1 business day we send your Affidavit Roadmap + Document Checklist + Fixed-Fee Quote + Timeline. Lawyer-client privilege from the first message, no consult fee, no obligation.
How do you prevent sham / convenience marriages?
Marriage entered only to obtain visa/PR/citizenship without genuine intent breaches CCC § 1497/1 (void) + Immigration Act § 12(7) (deportation + 5–99 year re-entry ban) + foreign penalties (UK Marriage Act / US 8 U.S.C. § 1325(c) up to 5 years + $250,000). We refuse the engagement on any red flag and file an AMLA report where statutory.
What do I have to do after the marriage is registered?
(1) Translate Khor.Ror.2 + Khor.Ror.3 + Apostille for foreign use; (2) update tax filing status (US joint/separate, UK HMRC, AU ATO); (3) change insurance beneficiaries; (4) update will + estate plan; (5) optionally convert to Non-O Marriage Visa; (6) update bank/property titles if desired. We offer a Post-Marriage Compliance Package separately.

Short answer: A Thai certificate of single status is issued by the district registrar of your registered domicile. It then has to be translated, have the translation certified by the Department of Consular Affairs and, where required, legalised by the destination embassy. Because receiving registrars usually accept only recently issued certificates, sequence the work backwards from your wedding date.
