Lawyer Wallace Bock and accountant Irving Kamsler, suspected of taking advantage of an elderly copper heiress, got the boot yesterday as executors of her $400 million estate.

Manhattan Surrogates Court Judge Kristin Booth Glen called the pair “unfit to serve” and suspended them from administrating the late Huguette Clark’s affairs.

The ruling came after Peter Schram, a lawyer for the county public administrator, accused Bock and Kamsler of failing to pay some $90 million in gift taxes and interest over the years.

The Manhattan DA’s Office is probing the handling of Clark’s finances.
