Identity Theft...

Here's a question and I hope you can help: I am trying to apply for a condo but unfortunately, my wife has been the victim of identity theft. Her son and daughter in law purchased properties worth well over one million dollars. Needless to say, it's ruined her credit. This is an ongoing case as well, about 10 years in the making with the authorities involved. I know that both my and my wife's credit will be checked, as this is nothing that we can keep a secret anyway, from them. I'd like to include this on a cover letter when handing in our co-op package/forms so that they will be informed well in advanced and not be surprised. My question, finally is how or what should I put on paper? Thanks for all input!
