Lease Purchase Agreement
Only some places where these treaties and agreements are republished are considered "official" and having a binding version of that agreement. So, even if you find a republished version through Google, that may not mean it is a binding replication of the text. Frequently, they are published officially online through particular websites sponsored by the international organization(s) that created the agreement.
Write a termination clause that explains the steps that one or both parties need to take in order to terminate the contract. For example, you may say that either party can terminate the agreement with a written 15-day prior notice to the other party. Also, include payment terms for any work completed to date that the customer is responsible for paying for this portion of the work. Write a dispute clause to establish the handling of a dispute between the two parties. For example, arbitration is one method the parties can agree to in the case where a dispute arises between them.
