One of the most common reasons for a spouse visa refusal is the absence of adequate evidence to prove the authenticity of the relationship, with the Home Office expecting substantial proof that your connection with your UK partner is honest and ongoing. UKVI case officers are always alert to spouse or partner visa applications that are not genuine, and if the Home Office has any reason to suspect that you are not in a genuine relationship with your British or settled partner in the UK, they will simply refuse the application.
To avoid this problem, you need to provide comprehensive documentation including photographs together, communication records such as emails and WhatsApp messages, joint financial documents, and testimonies from friends and family. For couples who cannot provide evidence of cohabitation due to cultural, religious reasons, or long-distance relationships, suitable proof includes texts, emails, letters and any form of communication to prove that the couple has kept in touch whilst apart.
