UK Spouse & Fiancé Visa from Thailand — Evidence Guide

Applicable visa categories

• Spouse / Civil Partner Visa (Family visa) (Appendix FM) — GOV.UK: usually a decision within 12 weeks when applying from outside the UK; varies by case and can take longer if extra checks are needed — check the official processing-times page
• Fiancé(e) / Proposed Civil Partner Visa (Appendix FM) — GOV.UK: usually within 12 weeks from outside the UK; varies by case
• Unmarried Partner Visa (Appendix FM) — GOV.UK: usually within 12 weeks from outside the UK; varies by case

What is different for Thai applicants

• No visa service at the embassy: the British Embassy Bangkok states that it does not provide visas and cannot advise on them. Partner applications are made online from outside the UK, followed by an appointment to give fingerprints and a photo at the visa application centre (VFS Global, per GOV.UK’s centre finder).
• TB certificate: Thailand is on the list of countries in the Immigration Rules (Appendix Tuberculosis). If you have lived in Thailand for 6 months or more and were living there in the last 6 months, a TB certificate is needed when you come to the UK for more than 6 months and also for any fiancé(e) or proposed civil partner application. The test must be done at a Home Office-approved clinic, and GOV.UK says the certificate is valid for 6 months from the date of the x-ray.
• English requirement: Thailand is not on GOV.UK’s list of majority English-speaking countries, so a first partner application needs English at CEFR level A1 or above in speaking and listening. Accepted proof is a SELT from an approved provider, a UK degree taught in English, or an overseas degree that Ecctis confirms is equivalent to a UK bachelor’s degree or higher and was taught in English, unless an exemption applies.
• Marrying in Thailand: GOV.UK says religious ceremonies are not valid on their own; a registrar at the district office must conduct the ceremony. In most provinces the British partner first needs a marital status affirmation from the British Embassy Bangkok, translated into Thai and legalised by Thailand’s Ministry of Foreign Affairs. The marriage certificates are issued in Thai, and GOV.UK asks for a certified translation of any document not in English or Welsh.

Document authentication (Thailand)

Thailand deposited its accession to the Hague Apostille Convention on 30 June 2026, but the Convention only enters into force for Thailand on 28 February 2027. Until then, Thai documents for use abroad are legalized by the Ministry of Foreign Affairs' Department of Consular Affairs rather than apostilled; check whether the destination country's embassy must also legalize them.

Issuing authority: Department of Consular Affairs — Nationality and Legalization Division (MFA Thailand).

Civil documents commonly required

• สูติบัตร (birth certificate)
• ทะเบียนบ้าน ท.ร.14 (house registration book)

• หนังสือสำคัญการเปลี่ยนชื่อ ช.3 (name-change certificate), where a name has changed
• Police certificate from the Special Branch of the Royal Thai Police

Common refusal grounds at UK Visas and Immigration (via VFS Global Thailand)

• Relationship not shown to be genuine and subsisting (Appendix FM, E-ECP.2.6). Where a couple are living apart, especially if they have not lived together before, Home Office caseworker guidance looks for a reasonable explanation for living apart and additional evidence of commitment, such as shared financial responsibility or visits.
• Financial requirement (E-ECP.3.1: £29,000 gross annual income, qualifying savings, or the benefit-based alternative in E-ECP.3.3) not met or not evidenced in the form Appendix FM-SE specifies, for example by relying on the Thai applicant’s own employment income, which E-ECP.3.2 does not list as a source for an application made from outside the UK.
• English-language requirement (E-ECP.4.1) not met: no A1 speaking-and-listening SELT from an approved provider, no qualifying degree, and no exemption.
• Marriage not valid under E-ECP.2.7, for example a religious or traditional ceremony that was never registered at a Thai district office. Caseworker guidance says this must not lead to automatic refusal; the caseworker then considers whether the couple are in a durable relationship similar to marriage for at least 2 years (the unmarried-partner definition).

What officers scrutinize on this corridor

• Commitment while living apart: the Home Office’s "Relationship with a partner" guidance lists money transfers and bank transactions as strong evidence for couples who are apart, for example transfers between the UK and Thailand.
• Visits: flight tickets and holiday bookings sit in the guidance’s "acceptable" tier, so records of trips between the UK and Thailand are worth keeping.
• The Thai marriage certificate issued at the district office (listed as strong evidence of a valid marriage) with a certified English translation that confirms it is accurate and gives its date and the translator’s full name and contact details.
• Communication history (LINE, WhatsApp, Messenger or similar): the guidance places communication records (certified transcripts) and photos in its "weak" tier and says chat and social-media evidence is not encouraged because it can be falsified and is hard to verify, though it still carries some weight. If you include it, add certified English translations of Thai-language messages and use it alongside stronger documents.
• Unmarried partners: documents showing both partners living at the same address over the same period, such as tenancy agreements or utility bills.
