Massachusetts Summary Process Answer is the legal document filed by a tenant in Massachusetts to respond to a landlord's complaint for eviction, also known as a Summary Process Complaint. The Answer is the tenant's opportunity to provide a defense against the eviction. It must be filed in court within 10 days of the tenant receiving the Summary Process Complaint. The Answer must contain all the tenant's defenses, including any applicable state or local laws or regulations that the tenant believes protect them from eviction. The Answer may include an Affirmative Defense, which is an argument that the complaint should be dismissed because of an issue with the landlord's complaint, or a Counterclaim, which is an argument that the landlord owes the tenant money, such as for unpaid rent or damages. The Answer must be signed by the tenant, and must include their current address. If the tenant is represented by an attorney, the Answer must also include the name and address of the attorney.
