Early stages of separating due to DH affair - tricky house situation

[fixuplooksharp]

So, never thought I’d be writing this. Here goes...
I recently found out my husband had been having an affair (while I was pregnant at one stage) and had previously had a one night stand. To say I’m shocked is an understatement, it’s so hard to take in. I can’t go on with him, it’s too much and I feel like he isn’t the person I married 13 years ago. We have 3 DC (11,7,3) and the thought of hurting them is just hideous.
We need to sort out living arrangements, the house situation is a really tricky one, it’s a family house on family land (his family) and due to tax etc his Dad still has a percentage of the house. My name is not on the mortgage or title deeds and it can’t be sold.
So, we (he) still have a mortgage, he can’t afford to go and rent anywhere and pay the mortgage on the family home. I know I would probably get help to rent somewhere but I feel like I’m starting from scratch with nothing, I won’t be able to get a mortgage and don’t have a deposit to rent, all this seems so unfair when until recently I thought I was in a happy marriage and none of this is my fault.
Any help or advice gratefully received, thank you

He could stay in house and give you spousal maintenance in addition to child maintenance. This would give you enough money to go and rent.

It depends on the title deeds it could be tied to farm or land etc until you know the legal set up you can't act, however a lawyer will be able to tell you it also depends on how much your FIL owns, is the mortgage in his name, is your husband on the deeds ? It could be that it is basically FIL house but he has a mortgage on it to raise funds and you and DH were paying towards mortgage like rent, in which case you will have virtually no claim on house on the other hand maybe house is in names of FIL and DH and they both own 50% in which case you have a claim for 25% of the equity

You are amazing op!
