Massachusetts Mutual Nondisclosure Agreement (MMA) is a legal agreement protecting confidential information from unauthorized disclosure, use, and reproduction. It is typically used to protect sensitive company information and trade secrets in business and employment relationships. The agreement is designed to ensure that confidential information is not disclosed to third parties without the consent of the parties involved. There are two main types of Massachusetts Mutual Nondisclosure Agreement: unilateral and mutual. Unilateral MMA is an agreement between one party to another, where only one party is obligated to protect the confidential information. Mutual MMA is an agreement between two or more parties, where all parties are obligated to protect the confidential information. Both types of agreements are legally binding and enforceable in a court of law.
