How to Prove Your Relationship
You will need to provide evidence of your relationship, such as documents from government agencies, banks, landlords, utility providers, or medical professionals. These documents should confirm your relationship, such as living together, sharing expenses, or being married or in a civil partnership.
Examples of acceptable evidence include:
Marriage or civil partnership certificate
Tenancy agreement, utility bills, or council tax bills showing shared living expenses
Bank statements from a joint account or confirming the same address
Letters from a healthcare professional confirming cohabitation
