Thank you for your question
My name is Clare
I shall do my best to help you but I need some further information first
Have they started divorce proceedings at all?
In fact, unless they both agree none of the funds can be released - so he can simply say he does not agree to the release of any of the money to the joint account either - which means that at least it will be safe.
If no agreement can be reached then he will have to issue divorce proceedings and within those ask the court to deal with the financial issues.
With an Order from the court the monies can be released!
I hope that this is of assistance - please ask if you need further details
