Items that can be used as proof of a common-law relationship include:
shared ownership of residential property
joint leases or rental agreements
bills for shared utility accounts, such as:
gas
electricity
telephone
joint utility accounts
important documents for both of you showing the same address, such as:
driver’s licenses
insurance policies
identification documents
You don’t need to include all these items to prove your relationship is real. We may consider other proof as well. Use the document checklist to find out what to submit with your application.
We don’t return photos, telephone bills or letters. Don’t send videos or CD-ROMs. We’ll return original documents such as marriage certificates and passports. However, you should send certified photocopies unless your checklist or country-specific requirements ask you to submit originals.
