Mass. Gen. Laws ch. 200A, § 9A
(c) The treasurer of a city, town or district holding funds owed to a corporation, organization, beneficiary or person entitled thereto that are presumed to be abandoned under this section shall post a notice entitled ''Notice of names of persons appearing to be owners of funds held by (insert city, town or district name), and deemed abandoned''. The notice shall specify the names of those persons who appear from available information to be entitled to such funds, shall provide a description of the appropriate method for claiming the funds and shall state a deadline for those funds to be claimed; provided, however, that the deadline shall not be less than 60 days after the date the notice was either postmarked or first posted on a website as provided in this section. The treasurer of the city, town or district may post such notice using either of the following methods:
(e) Once the final deadline has passed under subsection (d), the funds owed to the corporation, organization, beneficiary or person entitled thereto shall escheat to the city, town or district and the treasurer thereof shall record the funds as revenue in the General Fund of the city, town or district and the city, town or district shall not be liable to the corporation, organization, beneficiary or person for payment of those funds or for the underlying liability for which the funds were originally intended. Upon escheat, the funds shall be available to the city, town or district's appropriating authority for appropriation for any other public purpose. In addition to the notices required in this section, the treasurer of the city, town or district may initiate any other notices or communications that are directed in good faith toward making final disbursement of the funds to the corporation, organization, beneficiary or person entitled thereto.
Prior to escheat of the funds, the treasurer of the city, town or district shall hear all claims on funds that may arise and if it is clear, based on a preponderance of the evidence available to the treasurer at the time the claim is made, that the claimant is entitled to disbursement of the funds, the treasurer shall disburse funds to the claimant upon receipt by the treasurer of a written indemnification agreement from the claimant wherein the claimant agrees to hold the city, town or district and the treasurer of the city, town or district harmless in the event it is later determined that the claimant was not entitled to receipt of the funds. If it is not clear, based on a preponderance of the evidence before the treasurer at the time of the claim that the claimant is entitled to disbursement of the funds, the treasurer shall segregate the funds into a separate, interest-bearing account and shall notify the claimant of such action within 10 days. A claimant affected by this action may appeal within 20 days after receiving notice thereof to the district, municipal or superior court in the county in which the city, town or district is located. The claimant shall have a trial de novo. A party adversely affected by a decree or order of the district, municipal or superior court may appeal to the appeals court or the supreme judicial court within 20 days from the date of the decree.
If the validity of the claim shall be determined in favor of the claimant or another party, the treasurer shall disburse funds in accordance with the order of the court, including interest accrued. If the validity of the claim is determined to be not in favor of the claimant or another party or if the treasurer does not receive notice that an appeal has been filed within 1 year from the date the claimant was notified that funds were being withheld, then the funds, plus accrued interest, shall escheat to the city, town or district in the manner provided in this section.
If the claimant is domiciled in another state or country and the city, town or district determines that there is no reasonable assurance that the claimant will actually receive the payment provided for in this section in substantially full value, the superior court, in its discretion or upon a petition by the city, town or district, may order that the city, town or district retain the funds.
