Courts and legislatures in many US states—ranging from California to Massachusetts, and including Michigan—have adopted his ULC and ALI law-reform proposals. Law school courses and casebooks nationwide are organized around his law-reform work.
For the Uniform Law Commission, Waggoner served as the principal architect and drafter of the Uniform Probate Code revisions completed in the 1990s. He recently completed another round of UPC revisions dealing mainly with the treatment of children of assisted reproduction. He was also the reporter for other uniform acts: the Uniform Statutory Rule Against Perpetuities, the Uniform Simultaneous Death Act, and the Uniform Testamentary Additions to Trusts Act.
A symposium honoring his work on the UPC was held at the University of Michigan Law School in October 2011. The symposium, “The Uniform Probate Code: Remaking of American Succession Law,” was sponsored by the Foundation of the American College of Trust and Estate Counsel and the Michigan Journal of Law Reform. Symposium speakers included professors from law schools across the country.
For the American Law Institute, Waggoner served as the reporter for the Restatement (Third) of Property: Wills and Other Donative Transfers. Volume 1 of the new Restatement was published in 1999, volume 2 in 2003, and the third and final volume in 2011. Many judicial decisions have changed prior law or made new law on the basis of the Restatement.
In March 2012, Waggoner co-delivered (with Professor John Langbein of Yale Law School) the Joseph Trachtman Memorial Lecture at the annual meeting of the American College of Trust and Estate Counsel. This was his second Trachtman Lecture. Waggoner previously delivered the Mortimer H. Hess Memorial Lecture at the Association of the Bar of the City of New York and twice delivered the Tamisiea Lecture at the University of Iowa College of Law.
In December 2013, Waggoner received the Richard V. Wellman Award for Outstanding Contributions to Uniform Laws in the Field of Trusts and Estates. The award was presented by the Joint Editorial Board for Uniform Trust and Estate Acts (a joint commission composed of members from the Uniform Law Commission, the American Bar Association, and the American College of Trust and Estate Counsel).
He practiced law with Cravath, Swaine & Moore in New York City. As a captain in the US Army, he served from 1966 to 1968 with other military officers from the Air Force, Marines, and Navy on a joint staff in the Department of Defense. He is a life member of the American Law Institute, an academic fellow of the American College of Trust and Estate Counsel, an academician of the International Academy of Estate and Trust Law, and a life fellow of the Michigan State Bar Foundation. Waggoner retired at the beginning of 2012, after 44 years of teaching, 38 of which were at Michigan.
