What documents prove cohabitation?

Strong evidence includes joint tenancy agreements or mortgage statements, utility bills in both names at the same address, bank statements showing the same address, council tax bills listing both names, official correspondence addressed to both of you at the same address, and joint insurance policies.

Do we both need to be named on bills and documents?

Ideally, yes. Joint bills and documents in both names are the strongest evidence. However, you can also provide individual documents showing the same address. A combination of his bill at 123 High Street and her bank statement at 123 High Street also works.

What if we lived together abroad, not in the UK?

Cohabitation abroad counts towards the 2-year requirement. You need equivalent evidence from your country of residence: tenancy agreements, utility bills, bank statements, and other official documents showing the same address. Translations are needed for documents not in English.

Cohabitation Evidence for Partner Visa Applications

Q: How long do you need to have lived together for a partner visa?

You must have lived together in a relationship akin to marriage for at least 2 years. The 2-year period must be continuous, meaning you lived at the same address for the full period, though short breaks for work or travel are generally accepted if you can explain them.

Unmarried partner visa applications require evidence of at least 2 years of cohabitation. This guide covers the types of documents accepted, how to organise your evidence, what to do if you have gaps, and common mistakes that lead to refusals.

The 2-Year Requirement

Under the Immigration Rules, unmarried partners must demonstrate that they have been living together in a relationship akin to marriage or civil partnership for at least 2 years. This must be continuous, meaning you lived at the same address throughout the period.

Short breaks for work trips, family visits, or holidays are acceptable, but extended periods apart may undermine your claim. If you had any significant breaks, be prepared to explain them.

Types of Evidence

Strong Evidence (Joint Documents)

Joint tenancy agreement or mortgage
Joint utility bills (gas, electricity, water, internet)
Joint bank account statements
Joint council tax bill
Joint insurance policies
Correspondence from official bodies addressed to both of you

Supporting Evidence (Individual Documents at Same Address)

Individual bank statements showing the same address
HMRC correspondence at the same address
GP registration at the same address
Electoral register entries showing both at the same address
Driving licences showing the same address

How to Organise Your Evidence

Organise your evidence chronologically, covering the full 2-year period. Aim to have at least 6 pieces of evidence spread across the 2 years, with documents from different points in time. For example:

A joint tenancy agreement from the start of the period
Utility bills from several points during the period
Bank statements from the middle and end of the period
Council tax bills for each year

The goal is to show a continuous, unbroken period of cohabitation. Gaps in evidence can raise questions about whether you were actually living together throughout.

Common Pitfalls

All evidence from one date: Showing everything from one month does not prove continuous cohabitation over 2 years
No joint documents: Individual documents at the same address are weaker. Try to get at least some joint documents
Unexplained gaps: If there are months with no evidence, explain why
Different addresses: If you moved during the 2 years, provide evidence for each address

If You Lived Together Abroad

Cohabitation in another country counts. Provide equivalent evidence from that country, such as rental contracts, utility bills, and bank statements. Documents not in English must have certified translations.

Additional Relationship Evidence

Alongside cohabitation evidence, you should also provide evidence of a genuine relationship:

Communication evidence (messages, call logs)
Photographs together over the 2 years
Evidence of meeting each other's families
Evidence of shared financial responsibilities
Statements from friends and family

Building Evidence for the Future

If you are planning to apply for a partner visa in the future, start building your evidence now:

Put bills in joint names where possible
Open a joint bank account
Register on the electoral roll at the same address
Keep copies of all correspondence at your shared address
Take dated photographs together regularly

The more evidence you accumulate, the stronger your application will be.
