When proving a "genuine and subsisting relationship" to the Home Office, it's important to go beyond the usual photos and chat logs. One effective piece of evidence is joint financial commitments, like shared bank accounts, utility bills, or property leases. I once helped a client by providing records of joint savings accounts and proof of their shared responsibilities for bills, which showed long-term financial interdependence. Another powerful example is documentation of joint travel—flight tickets, accommodation bookings, and itineraries for trips taken together over the years. Additionally, providing statements from family or friends who can vouch for the authenticity of the relationship can strengthen the case. Lastly, showing plans for the future, such as joint insurance policies or wedding preparations, also helps demonstrate that the relationship is serious and ongoing. These pieces of evidence build a more comprehensive picture of the couple's life together.
