My great aunt used to own her own house. A couple of years ago she gifted it to another family member, to avoid inheritance tax. She pays a peppercorn rent. I don't think she's told her building insurance company about the change in circumstances, and I'm pretty sure that she needs to. I don't think she can insure the house any more, as she doesn't own it. I think the other family member needs to take out landlord's insurance. Does anyone know for definite?
