In a nutshell, my Father passed a few years ago, unbeknownst to me. My half sister attempted to submit a number of fraudulent wills (4). I stumbled onto his passing through State online records. Through court proceedings, It was ultimately agreed by the court he died intestate. There was talk of a criminal referral for the attempted fraud, but we decided in exchange for myself being named as executor we would make a compromise to close out the Estate forthwith. This Estate is of very nominal worth, it consists solely of his property. And that property just sold for less than 140K. The estate is not quite insolvent, but pretty close to being so. After all that, my question is the following. My Father had 2 bank checking/savings accounts, solely in his name, no cosigner just himself. These 2 accounts combined contained <50K. Although these accounts are being considered advanced distributions against my half sibling from the sale, I want to know how my sister was able to take possession of these accounts in the first place? Do I have any recourse against the banking institutions for releasing these funds? Any advice will be appreciated!
