I was in a business with someone else she agreed to buy my 50% of the business. A week before we settled the sale she told me to get the hell out of the business and that it was my problem because I wanted out of the business. She had made a verbal agreement and also we had dicuss a price at one of our corporate meetings. We are now going to court and I want to know if I can use this corporate paper as evidence in the trial.

Because you discussed a price, that does not mean in and of itself that she agreed to purchase it from you. In order to enforce that, you’ll have to prove to the court that she agreed to purchase your half of the business. If she doesn’t agree with that story in court, it’s going to be your word against hers, and absent of any proof (a written agreement or her admission that she had agreed to purchase it), it’s not likely the court will find in your favor.
