Massachusetts General Laws Part II. Real and Personal Property and Domestic Relations (Ch. 183-210) Ch. 190B, § 2-403

(a) The decedent's surviving spouse is entitled from the estate to a value at date of death, not exceeding $10,000 in excess of any security interests therein, in household furniture, automobiles, furnishings, appliances, and personal effects. If there is no surviving spouse, the decedent's children are entitled jointly to the same value. If encumbered chattels are selected and the value in excess of security interests, plus that of other exempt property, is less than $10,000, or if there is not $10,000 worth of exempt property in the estate, the spouse or children are entitled to other assets of the estate, if any, to the extent necessary to make up the $10,000 value. Rights to exempt property and assets needed to make up a deficiency of exempt property have priority over all unsecured claims against the estate, but the right to any assets to make up a deficiency of exempt property abates as necessary to permit earlier payment of the discretionary family allowance. These rights are in addition to any benefit or share passing to the surviving spouse or children by the decedent's will, unless otherwise provided, by intestate succession, or by way of elective share.

(b) The decedent's surviving spouse may remain in the house of the decedent for not more than 6 months next succeeding the date of death without being chargeable for rent.
