What Documents Are Needed For a UK Spouse Visa?

A UK spouse visa application needs more than a marriage certificate and a few photographs. For a Thai applicant joining a spouse in the UK, the documents should establish identity, a legally recognised marriage, a genuine relationship, the financial requirement, suitable accommodation and the applicant’s English language ability. The precise list depends on the couple’s circumstances.

1. Identity and immigration history

• The Thai applicant’s current passport or other valid travel document.
• Details and relevant pages from previous passports, including travel and visa history.
• Evidence of the UK sponsor’s identity and qualifying UK status.
• Accurate details of previous immigration applications and any refusals.
• Details of children and previous partners where requested on the application.

The online form will request personal and immigration history information. Prepare this carefully so that dates, names and previous applications are consistent with the supporting documents.

2. Marriage and relationship evidence

Include the official marriage certificate. For a marriage registered in Thailand, provide a certified English translation where required. If either partner was previously married, include evidence that the earlier marriage legally ended.

Explain how the relationship developed and how you have maintained it. Depending on your circumstances, relevant evidence may include:

• Records of visits and time spent together.
• Evidence of living together or sharing expenses.
• A modest selection of photographs over the course of the relationship.
• Evidence of regular contact during periods apart.
• Information about children you have together.

Choose evidence that tells a coherent story. Hundreds of screenshots cannot compensate for contradictory dates or missing core documents. Read our UK spouse visa requirements guide for the eligibility rules behind this checklist.

3. Financial documents

The documents depend on which permitted income or savings you rely on. For straightforward salaried employment, the evidence will commonly include the relevant payslips, matching bank statements and an employer letter confirming the job, salary, employment period and authenticity of the payslips.

The evidence period and calculation may differ if the sponsor changed jobs, has variable earnings, is self-employed, owns a limited company, receives a pension, has rental income or relies on cash savings. Combining sources adds further rules. Check the GOV.UK evidence guidance and assess the applicable category before submitting.

For many new partner applications, the usual minimum income requirement in September 2026 is £29,000 a year, but exceptions and transitional arrangements exist. The figure alone does not establish that the specified evidence rules have been met.

4. UK accommodation evidence

Show where the couple will live in the UK and the sponsor’s right to occupy the property. Depending on the arrangement, useful evidence may include a tenancy agreement, title or mortgage documents, and a letter from the owner or main occupier if you will stay with family. Explain who else lives at the address.

The accommodation must be suitable for the household. A sponsor does not have to own a home to meet this requirement.

5. English language evidence

For a first spouse visa, the applicant commonly meets the English requirement through an approved speaking and listening test at at least A1 level. A qualifying degree or an exemption may apply instead. Check the current GOV.UK English language guidance before booking or relying on a certificate.

6. TB certificate, translations and other records

A Thai applicant applying to live in the UK may need a tuberculosis certificate from an approved clinic, subject to the applicable rules and exemptions. Check whether a TB test is required before arranging one.

Documents that are not in English or Welsh generally need a certified translation meeting UKVI’s requirements. This may include a Thai marriage certificate, divorce document or other Thai-language evidence. Children applying alongside the spouse will need their own relevant identity, relationship and parental responsibility evidence.

How should you organise the application?

1. Confirm that a spouse visa is the correct route and check the current requirements.
2. Calculate the financial requirement and identify the correct evidence category.
3. Prepare identity, marriage, relationship, accommodation and English evidence.
4. Check names, dates and figures across the form and documents.
5. Arrange translations and any required TB test.
6. Follow the application’s instructions for submitting documents and attending the biometrics appointment.

Questions from other families

If your Thai spouse has a child who may also move to the UK, the evidence needs separate attention. Read our forum discussion on proving sole responsibility for a child. You can ask a question in the UK spouse and family visa forum.
