So of the OP has paid for the next year, her name is on the tenancy, the other person isn’t on the tenancy and has no moral or legal obligation after next week when the year she paid for is up? I’d be sending a formal letter to her home address giving 7 days’ notice with charges laid out for any further days, but with a firm instruction to vacate the field.
