My H and I are splitting up for various reasons, mainly due to his alcohol abuse. A few years back I found out his mother had access to our joint bank account and consistently snooped through our finances, often reminding him to pay bills or ask me to transfer x amount of money etc. She also took money out of our account for things she was “owed”. My XH always denied her having access and then I finally got the proof I needed. I want to prosecute for financial abuse - should I give it a go?
