How to write contracts 
Discuss the specific details with the person with whom you are creating a contract. 
Both parties should agree upon the terms of the contract before drafting it. Usually, someone " offers " terms and the other party " accepts " terms.
If the accepting party would like to negotiate before agreeing to the terms, that is fine. In most cases, once a counter-offer is introduced, the original offer no longer stands.
