customer is in an independent living facility. online banking is set up on his account (whoever did it had access to all the right information); a debit card is ordered, transactions start going through (small debit card purchases, a larger online payment to an individual). customer passes away. POA (one of the children) report the fraudulent activity.

Can the executor sign affidavits stating the transactions were not authorized? Unfortunately they were not discovered until after the account holder died. all the fraudulent activity is very recent (within less than 2 weeks of his death).

Yes- the executor has the legal authority to sign affidavits on behalf of the decedent's estate.

thanks! Wasn't sure since the only one who would know for sure if any of transactions were legitimate would be the deceased.
