Is there any way to head this situation off at the pass (details inside)

In his seeming unending quest to make my life miserable, my ex-husband has decided to file a police report saying that I stole his identity. I did not steal his identity or use his name and personal information in any way whatsoever. Never mind that what he is accusing me of happened five years ago – while we still married – and involved a property we both had interest in, he is determined to use this to try to cause trouble for me. This is the same person who filed a false CPS report, made more than one false 911 call, and sent a repo man after me. I am fairly sure that his plan is to give the police all of my personal information including address and where I am teaching if for no other reason then to embarrass me. My goal is to avoid having the police show up at work, or even at home and all of the questions that go with being questioned by a police officer. I have already contacted my attorney, but I am looking for some advice in the meantime.
