Well, the only person who suffered from you not updating your finances is you. It was clearly not a move done to hide your situation as your ex already knew you'd lost your job.


Plus didn't the lawyer tell you not to bother updating that?


In any case, I would phrase that you didn't update that, rather than failing to disclose it.


His failure to disclose his inheritance was far earlier, as you've said.


I would keep evidence of his numerous attempts to give you money, as it can be seen as a guilty conscience as well as trying to bribe you to get back together with him.

It's clear that HE thinks he should give you money, so make it legal and get that 10K (or other amount) through the lawyer/judge if you can.
