The Lackner Group, Inc. has been developing tools for estate administration since its incorporation in 1985. Its flagship product, the 6-in-1 Estate Administration System, has been on the market since early 1986. The product is used by law firms, accounting firms and banks throughout the United States.

Vince Lackner developed the 6-in-1 Estate Administration System in response to a wish list drawn up by the Computer Probate Systems Committee of the American Bar Association in 1983, which sought a software program that would prepare federal and state tax returns and court accountings after just one entry of each transaction.

The Lackner Group team has continued to build the 6-in-1 product beyond Vince’s initial vision. Today the company’s suite of products offers complete and robust solutions for estate and trust administration across the nation.
