Vt. Stat. tit. 14 § 2927
After the trust of a guardian is terminated, if the ward or the ward's legal representatives are dissatisfied with the account as allowed by the Probate Division of the Superior Court during the continuance of the trust, within two years, and if the ward or the legal representatives do not at the time of the termination of the trust reside in this State, within four years thereafter, they may file a motion to reopen the estate for a reexamination of the account. After notice as provided by the Rules of Probate Procedure, the court shall reexamine accounts previously allowed. A party may appeal from the decision of the Probate Division to the Civil Division of the Superior Court. The final allowance of accounts in these proceedings shall be conclusive between the parties.
