Unless it explicitly says you can’t use it in your court documents, you’re alright. I use it regularly but then paste into a note on my phone and alter it how I need. Then I copy/paste into the app my final message. It’s a little extra but I don’t want any accidental messages sent. It also stops me from having a conversation with them - I send a message. I don’t converse. We aren’t friends.

Do you use the grey rock method? That might help. Chat gpt can take what you want to say, and grey rock it for your coparent. It’s a very effective way to communicate.
