What type of lawyer do I use for a HIPPA law violation? My sister in law created a logon and was viewing my medical records?

Creating phony logins for someone else's records, particularly confidential records like medical records, bank records, and so on is actually a criminal offense. 2C:20-25 and therefore should be reported to the prosecutor if you have evidence that your sister in law has access to your login information. You can certainly also pursue civil damages as well because it is not necessarily a HIPPA violation alone but a violation of protected computer information. One note, is if you leave your login information in a public place then it might be harder to prove criminal intent on the part of your sister-in-law, but if you had password protection and so on, then discuss it with the prosecutor of your county.
