FindLaw links to estate-planning information available online. To find treatises on estate planning in a particular state, see Searching the Law: The States by Francis R. Doyle (last published in 2003). The Estates, Gifts and Trusts Portfolios in BNA's Tax Management Portfolios series (mostly the 800s) provide detailed discussions of a wide range of estate planning strategies and vehicles. Natalie Choate's Life and Death Planning for Retirement Benefits (Ataxplan Publications) is a classic treatise on the topic.
