This has got to be one of the oddest posts that I've seen in a while.
1) OP knows that his credit report was accessed
2) OP knows who accessed his credit report
3) OP knows why the party accessed his credit report
4) A party desiring to know an address...ran credit to obtain it?!
I have to tell you that there are very strict policies in place that govern who can access credit in banks. Typically, it requires an application from the party before a bank employee can run it. Further, the information typically is automated and uploads to an application. At least in larger banks that is the "norm" for how it works.
I find this whole thing quite strange unless OP receives alimony and is co-habitating....
