My elderly mother (78) recently widowed, was asked by a friend if they could store a sofa in her now newly empty garage.
She agreed and friend turned up to store said sofa with her daughter and daughter's boyfriend. Seeing a mostly empty garage the daughter's boyfriend took it upon himself to tell his father (I have no idea who these people are) of the location, and he has now dumped a variety of crap (mattress, furniture, motorbike) in there without permission.
Am I within my rights to remove all this stuff and dump it? Mum has asked this "friend" to get her acquaintance to remove it all by the weekend.
AIBU to think this is out of order and what do I do if they don't remove it?
