I’m not a lawyer but it’s my understanding, in the US anyway, that an inheritance is separate from marital property so long as it’s kept separate. For instance, if he inherits the property, pays all the maintenance and upkeep himself, it’d stay separate. If he inherited it, and the used funds from your joint checking account that you contribute to, to fix it up and pay maintenance, then you might have some claim.
I’d suggest you have at least a visit with a lawyer to figure out your rights and get a clear picture of what your financial picture might be in divorce. Generally, things to consider include: Home equity - if you have any. If you bought the home together during your marriage the equity should be split evenly. If one I if you owned the house prior to marriage but commingled funds used to pay the mortgage etc then some of the equity would become community property in a community property state.
If you earn significantly less than him, you would likely receive spousal support. If your incomes are equivalent you would not. If so, I’d recommend getting an equivalent amount in a lump sum, house equity or other assets. If he left the country you’d probably never be able to enforce him paying those alimony checks.Better to have the bird in the hand if that’s what he’s threatening to do.
Retirement accounts or pensions: benefits earned during the marriage should be split equally. A QDRO is a formal division of a pension through divorce . There are formulas for that and has to be done properly. IRAs and 401ks are easier to split.
But most important at present is to look after your future. Get your income to a point that it can support you, if it isn’t already. Get financial ducks in a row. This guy has known your daughter knew about his infidelity for TWO years and he’s done nothing about it. He doesn’t have your interests at heart and he’s unlikely to suddenly wake up. Plan accordingly .
