Today, about half of all adults are unmarried. Many of those are in significant relationships-some intimate, others based in friendship, finances, or family ties-but the law offers them few protections. With this book, noted family-law expert John G. Culhane takes us on a guided tour of how the march toward marriage equality spun off a number of other legal statuses, and explores how the law has expanded and where it falls short. This lively living history is grounded in relatable, in-depth interviews that give voice to the millions of Americans building family structures outside the protections of marriage. Culhane proposes an updated legal status that offers flexible and portable benefits for a diverse range of commitments and needs. This "choose your own adventure" structure more accurately reflects, and more equitably protects, the many kinds of families we choose to build.
