I am thinking that XH is using the latest court filing as a backdoor fishing expedition to try and find out about your current financial situation because, I assume, he is experiencing some financial difficulties in his life.
I would want to have a L to work with the court to shut this notion of XH's quickly that he can just hope the Court would open up your financial records to him.
Ohhhh...to be a fly on XH's wall in his out with his banshee of OW screaming into his ear! Maybe she found out XW is no Daddy Warbucks after all.
