Should I be worried? Niece living in my mums house

[tubbinthug]

Bit of a long story, so apologies, but could do with some advice.
My Mum has teminal cancer, and is now bed ridden. She has moved into the front room of my brothers house, and my Niece has moved in to my mum's house to keep it occupied. However Niece's boyfriend is spending most nights with her at my Mum's house. He's 12 years older than her, has significant debts from gambling and when he's not at my mum's, he lives with his Mum. My concern is that when my Mum passes away, we will have problems getting rid of them from the house. Will this be an issue?

Thanks for the responses. Theres no contract in place at all. Niece is a beneficiary in Mum's will, so won't get her share unless the house is sold, but concern is he'll be getting stuck in there and it'll be tough to shift him back out.

LPA is already registered, but not activated as Mum is still capable. My brother and I are the attorneys. Mum has agreed to Niece moving in, so in some ways I am sticking my nose in where it isn't wanted, but I am also an executor for Mum's will, together with my brother, so I don't want problems when Mum goes. Another point is half the house was put into trust when Dad died, and I am also one of the trustees, together with my brother. So it's complicated.
