If you see indications that it might come to that, I would highly suggest to record the communications.
Understand the laws in your state, which vary. Some states are "one-party consent" meaning if you're a party to the conversation you can record without the other person's knowledge. Others are "two-party consent" in which both parties need to be aware of the recording.
Hopefully it doesn't come to that, but knowledge = power.
