He may well be able to force a sale.
The problem with you keeping all the house and him keeping all the pension is twofold:
- how does he adequately house himself
- how are you looked after in retirement.
Generally courts will want you to have equality of income in retirement and to make sure that you're both housed appropriately.
It is possible to offset pensions against house, but it's unlikely if he's against it. And offsetting the whole lot is usually a bad idea for both parties.
That said. It's important to look at the full picture. So, savings, investments, salary, years till retirement, children (needs and ages etc) as they're all important factors in how things are split.
They'll also affect what's possible. For instance, if there were a load of cash savings or accessible investments that could enable him to adequately house himself, then there might be a clever offset you can do. Etc.
Could you buy his half out? So stay put but pay him half market value?
We don't have enough info to work out what's reasonable. But generally you can't force him to take all the pension and demand you keep all the house. He can probably force a sale if he can't house himself without the equity.
