Generally, goods and services valued at $500 or more require a written agreement. Additionally, if a contract may take a year or more, or is expected to last longer than one year, a written agreement is required.
Although a document must be signed by each party to be considered legally binding, the mere presence of signatures does not guarantee that an agreement is enforceable in court. To be considered a legally binding contract or document, three critical elements must also be present: Subject, Consideration, and Capacity.
There are different ways to send a new contract to clients. You can upload to a Google Drive and send a link to download, attach a PDF to an email, or use a service like to send.
