Yes, please get a divorce lawyer. Yes, as mentioned, they’ll have seen this before.
it may be your husband has an accounting app on his phone. He’ll likely have an accountant that will have access to the system to prepare your husband’s tax returns, which then can be searched so eventually, some financial information will be found. Whatever information you have, will help. Particularly he details about the private pension that was built up with marital funds. This is really good news because his money is documented. The deposits into this pension would be tractable to a bank account. Your lawyer will use a forensic accountant to find out.
whether he has an OW or not now is irrelevant. His behaviour is atrocious and has irrevocably broken your marriage.
i wouldn’t file for divorce on line. Get a lawyer. You at least, at a minimum, are entitled to a portion of his business and most definitely his pension pot - which could be substantially more than your house deposit. It is a lever for negotiation. You’re entitled to it. He’s not been contributing fairly to even his own living expenses let alone marital home costs. It is marital assets.
have you considered giving notice on the Liz ce you’re renting now so that you can get away from him and also tell your adult daughter it is time she finds her isn Liz e as you’ll be leaving this rental so you’ll be able to look for something smaller and more affordable?
do NOT share your financial information with anyone. Play poor. Don’t share the amount of funds you have remaining from your inheritance or how much your business is making. Play poor if anything. That youve been supporting him and your daughter ion £100 a week.
your daughter has shown you who she is, what she thinks of you and how much help she’s wiling to give you. Treat her accordingly. She’s not on your side. Do not confide in her or tell her anything she doesn’t need to know. Tell her only what you want your husband to know.
when you’re at the spa, don’t tell anyone where you are. They don’t need to know you have funds for a spa break. Play poor.
above anything else, you deserve better.
