The defendant can ask for either money damages or a specific performance, such as the return of goods or services that the defendant believes were wrongfully taken or withheld. Types of Massachusetts Small Claims Counterclaims include: Breach of Contract, Negligence, Trespass, Fraud, Conversion, and Unjust Enrichment.
