My question involves child abuse or neglect in the State of: New Jersey

My soon to be ex-wife is emotionally abusive to me and my daughter and for evidence I have been recording conversations. I know NJ is a one-party consent state and I'm in the house for all of the recordings. Even if I'm not participating in the conversation, am I considered a party? I want to make sure what I'm doing is legal. In some conversations I am involved and talking so I would think I pass the "party in the conversation" test.

I plan to talk to a lawyer soon but if I should change how I'm recording for it to be a) legal and b) admissible in court I'd appreciate the help.
