I'm so pleased that you're making new plans, and getting out there, and taking care of your finances, Dilly. I think getting a solicitor on the job - and maybe a forensic accountant, if you think your H has been dishonest about his payout or hiding money away from you (and the sums involved warrant what a FA would cost) is an excellent act of boundary setting and self care. I think the sooner you can act, the better - your H is up to something and I think you've been very compliant with him for a long time and the second you withdraw that, he may react in ways that aren't okay with you.
