How to write a UK spouse visa relationship letter

Why a relationship letter matters

UKVI must be satisfied that your relationship is genuine and subsisting. Documents alone — marriage certificates, photos, bank statements — do not tell the full story. A well-written relationship statement gives the caseworker context and helps them understand your evidence.

A weak or generic letter will not cause a refusal on its own, but it can weaken an otherwise strong application — especially if other evidence is thin.

What to include

Structure your letter chronologically:

1. How you met

• When and where you first met
• How you were introduced (in person, online, through friends)
• What attracted you to each other

2. Relationship development

• Key milestones: first date, becoming exclusive, meeting families
• How you maintained contact (especially if long-distance)
• Visits to each other's countries with dates

3. Marriage or durable partnership

• When and where you married (or when you formed a durable relationship)
• Details of the ceremony or commitment
• How your families responded

4. Living arrangements and contact

• Current living situation (together or apart)
• How often you communicate and visit
• Shared finances, plans, or responsibilities

5. Plans for the UK

• Where you plan to live
• Employment or study plans
• How you will build your life together

What to avoid

• Generic templates — caseworkers recognise copied text
• Contradictions — dates or facts that do not match other evidence
• Repeating documents — the letter should add context, not duplicate certificates
• Identical letters from both partners — write in your own words
• Excessive length — 2–4 pages is usually sufficient

Example opening (married couple)

My name is [Name] and I am a British citizen. I am applying for my wife, [Name], to join me in the UK. We met in [Month Year] when [brief context]. We began our relationship in [Month Year] and married on [Date] at [Location]. This statement describes our relationship and refers to the supporting evidence in our application.

Example opening (unmarried partner)

My name is [Name] and I am applying for my partner, [Name], to join me in the UK under the unmarried partner route. We have been in a durable relationship since [Date] and have lived together since [Date] at [Address]. This statement explains our relationship history and refers to the evidence we have provided.

Linking to your evidence

Reference evidence by description, not by attaching it again:

• "Photographs from our wedding are included in Appendix A"
• "Flight bookings and boarding passes for my visits to [Country] are in Appendix B"
• "Screenshots of our daily communication are in Appendix C"

After you write it

• Both partners should write separate statements
• Check dates and facts against your other documents
• Ask someone to read it for clarity and consistency
• Include it in your organised application pack
