In New Jersey, by statute (N.J.S.A. 3B:23-24) an executor is required on paying a beneficiary his or her share of the estate, to take a Refunding Bond and Release from the beneficiary and to file the bond in the Surrogate's Court. The statute requires that the Refunding Bond and Release be in the amount or value of the beneficiary's share of the estate. The Refunding Bond and Release must be signed by the beneficiary before a Notary Public or attorney. If the beneficiary is a minor or incapacitated person, the Refunding Bond and Release must be signed by the guardian of the property. The Refunding Bond and Release has a dual purpose: (1) Refunding - To refund to the executor out of his share of the estate his ratable part of any unpaid debts, owed by the testator, if there are no other assets to pay them; and (2) Release - To discharge the executor of an estate of his duties upon distribution to the beneficiary of her share of the estate.
You have been through such an ordeal here, and my only idea by way of a solution is to seek redress through mediation and/or litigation. Seeking judicial intervention through legal counsel is, in my opinion, the only step that will afford any meaningful relief to you based on your brother's conduct. You cannot go back in time and undo the signing and everything else that has taken place, but you can go to Court and prove up duress, undue influence, fraud, breach of fiduciary duty, etc.
