If they were looking at your records electronically, it is in a log somewhere on the computers involved and a lawyer can get the ball rolling on getting those computers records or even getting the computers seized if they are good enough. But you don't want to go down that road. You will not just ruin their careers, they will be sent to jail for something like that and perhaps even be made an example of for breaking HIPPA laws. Also you'll be including people who have nothing to do with your family problems. And right now with the "forced" transition to electronic medical records going on they will be made examples of so we can all feel safe about our records. Get a lawyer who specializes in medical liability with a good knowledge of HIPPA laws and have him threaten the shit out of them. Show them the error of their ways, but don't press charges, then you'll be the bigger guy to everone and have a big fat hammer over their dumbasses. Especially good if they're the harpie kind of in-law who starts shit every few months. Jail keep a motherfucka in check 9 times outta 10 . Good Luck.
