Non contributing family

paigesaunt

I live with my adult son, his girlfriend and their baby. We live in the family home my son was brought up in. Since my husband left me 3 years ago I've struggled on a low income to keep paying the mortgage payments so we have a home, but I'm close to breaking point with worry about debts going unpaid, but no matter how bad I tell them it is they carry on their lives as if they're teenagers eating crisps, playing play station games sitting in bed all day (with the baby)

My son is expecting some inheritance but it's been constantly delayed for reasons unknown to me, his grandfather died two years ago, I believe his father (my ex husband) is the executor and he is untrustworthy to say the least. From this inheritance my son says he will pay the rent/keep for his family, but I'm not sure how much longer I can go on.
How do you make a 24 year old help financially, or the alternitive, move out with your baby grandson, something which will break my heart.
