Question

How does getting things in writing help resolve conflicts

Answer 1

It give you visual proof that someone agreed or disagreed about something or someone. For example, It's like a contract. Say I agreed to pay someone's bills than I stopped paying. You have a contract that I agreed to pay your bills.

Answer 2

It gives you visual proof that someone agreed to something, so that, later on, they can't say they didn't agree to that. It's like when you sign a contract, it is proof of the agreement.
