The Paris Agreement
Define the Scope of the Work - The terms constitute the body of the contract. Start off by clearly defining what it is the scope of the work or service you are to provide, and the timeline you propose to complete the work. Be specific. Don't simply say you will renovate a client's kitchen. Provide details of the cabinet designs, countertops, and other materials and work you will provide. If applicable, give a timeframe for each phase of a project.
Legal Contracts - Under state laws, only a few category of contracts must be in writing, such as a mortgage contract or contracts covering more than a year. It's still a good idea, however, to have a written agreement for business transactions beyond an ordinary sale of goods. There is no law requiring a lawyer to write your contract. If the transaction is relatively simple, the contract can also be simple. But you also have to pay attention to certain details to avoid issues arising later.
