The bank has to comply with the court order unless it can get it quashed. The bank doesn't really have a dog in this fight (it's not their money), but it should have standing to have its obligation clarified by the court. The elderly owner has standing to argue that the son has no ownership rights and that the court should lift its order. The bank's attorney might be able to argue the same thing, but only from the perspective of getting its duty clarified.
Put the hold on the account and then decide who, if anyone, will argue to have it lifted.
