Most contracts are enforceable whether they are oral or written.
Nonetheless, you should always have written contracts for all your business relationships. When the terms of a contract are written down, the parties are likely to create a more complete and thorough agreement than they would by oral agreement. A hastily made oral agreement is likely to have gaps that will have to be resolved later - when the relationship may have deteriorated. A written agreement eliminates disputes over who promised what. Some types of contracts must be in writing to be enforced.
