This book provides a comprehensive, yet easily understandable overview of a widespread and problematic form of property ownership in the United States known as heirs' property, a form of property ownership that typically arises due to a lack of estate planning. There has been growing awareness about various heirs' property problems, including massive, decades-long, involuntary loss of land and homes, property loss that has disproportionately (though not exclusively) impacted Black and Brown families. This book should increase that awareness among lawyers, the general public, and policymakers. Just as importantly, the book offers many practical solutions for those seeking to address a variety of heirs' property problems. The contributing authors possess deep expertise in working on a range of heirs' property issues, including Thomas Mitchell, the lead co-editor and contributing author, who was awarded the Mac Arthur Genius Grant in large part for his heirs' property work. These authors include academics, leaders and key staff members of various nonprofit organizations that do important heirs' property work, grassroot activists, and prominent attorneys in private practice.
