Protect Yourself
What is the name of your state? NJ
1. Tape record everything. As long as you are part of the conversation, you can tape record a conversation - I believe without even notifying the other party - however, this might be wise. You can buy a voice recorder almost anywhere: Target, Ebay, Best Buy
2. You might also consider recording what happens inside your home, as a precaution so that you have proof if the issue is ever presented in court.
3. Obtain all records from DYFS/Police and find out who is making the reports, then sue for libel, slander and/or defamation.
4. If you do drink, document everything - where, how much, witnesses, to show that it is not in front of the child, and does not affect your functioning around the child. Know where to get an alcohol test to prove to the Judge that you were sober at time of incident and protect yourself!
