Massachusetts Exhibit 3 refers to a type of legal document filed in Massachusetts courts. It is a type of affidavit, which is a sworn statement made under oath, and is used to provide evidence in a legal proceeding. The Exhibit 3 document is typically used in divorce proceedings and other family law cases. It is a statement of financial information, which must include income, assets, and liabilities of the signer. The document must be signed and notarized in order to be legally binding. There are two types of Massachusetts Exhibit 3 documents: the Long Form and the Short Form. The Long Form contains a more detailed description of the financial information, while the Short Form is a shorter version of the document.
