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.
Describe your obligations, including the service you must perform to fulfill your obligations under the contract and be as detailed as possible. For example, if you are writing a marketing brochure for a customer, describe the length of the brochure, the purpose of the brochure and establish that you are only responsible for providing the text, and not the layout or design, for the brochure.
