A written contract is the best way to avoid confusion and ensure that both parties agree to the same terms. 

If one party breaches the agreement, a written contract can allow you to assert your rights and enforce the contract. A contract is a legally binding agreement between two or more parties that defines and governs the rights and duties of the parties. Generally for a contract to be enforceable, there must be an offer, acceptance, consideration, capacity, and a meeting of the minds. Four contracts frequently needed by entrepreneurs are: Independent Contractor Agreements, Client Services Agreements, Copyright Assignment Agreements, and Operating Agreements.
