@Finallyfeelstrong See my previous post (sorry- mistyped your username.)
Who has helped him write this will?
Was it a solicitor (or someone running a will franchise?)
The reason being....if a solicitor drew up the will, it will be legal. A solicitor can't include anything that is illegal and can be easily challenged.
Or has your DH simply written it himself?
I suspect you may have misread some parts. Wills are written in legal language.
For example, you cannot be the Guardian to his child if the child's mother is alive. This is not legal.
So I expect the will states that if neither parent is alive, you as a step mum would be guardian.
I am really confused over who owns what. There are two houses- one you say you renovated but also you say you paid rent for it. So which is it?
Do you own a house in your name? Who owns the family house?
Is there a big age gap going on here too? He has grandchildren and you have children still at home.
Sorry but your post is really confusing - can you explain a bit more?
