Ex was paying CMS via deduction of earnings via his salary for around 18 months.. We've just had an annual review which has shown he's earning significantly higher which means DDs maintenance will be increased. However, this will now be sent via direct pay. Ex and I have zero contact whatsoever. He sees DD at a contact centre currently as a result of domestic abuse. I'm really worried he will use this as an opportunity to mess around and not pay DDs maintenance. I also do not think he has my current bank details. Is it simply a case of me calling CMS to ask them to pass my bank details across to him and reiterate if he doesn't comply to direct pay that the arrangement will move back to deduction of earnings. Has anyone had experience of this?
