Core Services: Affidavit & Legal Declarations
We specialize in drafting, witnessing, and legalizing affidavits for various needs.
1. Affidavit of Freedom to Marry
This is the most common Affidavit Service in Bangkok for expats. To register a marriage in Thailand, foreigners must provide an affidavit stating they are single and free to marry. We assist in drafting this document, guiding you through the embassy affirmation process, translating it into Thai, and legalizing it at the Ministry of Foreign Affairs (MFA).
2. Income Affidavit / Letter of Support
While many embassies have stopped issuing income letters, some still provide Income Affidavits for visa extensions (Retirement/Marriage). Alternatively, we assist in drafting an "Affidavit of Support" for visa applications where a sponsor is financially supporting an applicant.
3. Statutory Declarations & Oaths
Need to declare a fact legally? We assist with Statutory Declarations for various purposes: declaring a name change, confirming identity (One and the Same Person Affidavit), declaring loss of documents (Passport/ID), or affirming address proof. Our Notarial Services Attorneys are authorized to administer these oaths.
4. Certified Translation (30+ Languages)
Affidavits issued in English or other foreign languages must be translated into Thai to be used for official purposes in Thailand (like marriage registration). NYC Translation Center provides certified translations by Ministry of Justice registered translators, ensuring acceptance by Thai authorities.
5. MFA Legalization & Embassy Attestation
For an affidavit to be valid in Thailand, it often needs to pass through the Ministry of Foreign Affairs (MFA). We offer a "Full Loop" service: Translation -> Legalization at MFA -> Delivery to you. We handle the queues at Chaeng Watthana so you don't have to.
6. Notary Public Services
We provide full Notary Public services for authenticating signatures on affidavits intended for use abroad. Whether it's for property transactions in the UK, banking in the USA, or legal matters in Australia, our attorney's stamp and signature are internationally recognized.
7. Police Clearance & Criminal Record Check
Often required alongside affidavits for visa or employment purposes. We assist Expats in obtaining the Police Clearance Certificate from the Royal Thai Police Headquarters, handling the complex paperwork and fingerprinting process.
8. Marriage Registration Service
Beyond the affidavit, we offer a complete Marriage Registration service. We take your "Affidavit of Freedom to Marry," translate and legalize it, and then accompany you to the District Office (Amphur) to ensure your marriage is registered smoothly without communication barriers.
