He had the witness box pre signed and I just had to sign my name. So people clearly are prepared to witness things they’ve not actually witnessing
I wonder if you could start dropping into conversation that you are exploring legal options on his intent to defraud you.
You can't forgive this no - you would be an absolute fool to. He isn't who you thought he was. And think about it - either, you can be pretty sure that the children would remain with you for the majority of the time if you split so he was fully intending to defraud them out of the rights to their own home if you split... OR he would have seen himself using his fraud to strip you of assets to the point where, if you split, he's end up having the children as he'd made sure that you couldn't afford to house them :(
As everyone else on here has said, marriage makes you legally a team, a unit. It's for the protection of everyone but the children most of all. He's a fraudster who was out to cut you out of your legal, financial rights. Absolutely horrendous, and totally illegal.
Don't feel you need to do anything quickly - EXCEPT FOR ONE THING. If you have a very good local family solicitor, have a consultation with them NOW. Because then, they won't be able to act for your husband.
Right now, you don't just have rights to 50% of your assets, you have a right to more as you'll remain primary carer for the children.
Don't give up a penny of those rights for this nasty shark.
Sit tight, let everything sink in, tune him out. Just be for a bit and get a handle on the shock you've had.
Then - get that very very good solicitor and divorce him. You can do it, you should do it. And you'll get more than 50%
Unreasonable behaviour? How about fraud - wow, that will be a good one for the divorce form eh?
Someone I am close to divorced with young children, she'd not even contributed anywhere near equally as he had a property before their marriage which was then sold to fund their home. But, she'd given up her careeer for the kids. She got over 70% of the house worth and half his pension.
