Me. Stat. tit. 36 § 4079
Personal representatives are liable to the State on their administration bonds for all taxes assessable under this chapter and interest on those taxes. Whenever no administration bond is otherwise required, and except as otherwise provided in this section, the Probate Court, notwithstanding any provision of Title 18-C, shall require a bond payable to the court sufficient to secure the payment of all estate taxes and interest conditioned in substance to pay all estate taxes due to the State from the estate of the deceased with interest thereon. A bond to secure the payment of estate taxes is not required when the Probate Court finds that any estate tax due and to become due the State is reasonably secured by the lien upon real estate as provided in this chapter or by any other adequate security. An action for the recovery of estate taxes and interest lies on either of the bonds. [2017, c. 402, Pt. C, §104(AMD); 2019, c. 417, Pt. B, §14(AFF).]
