When M.R. and E.R. decided to call it quits after more than 20 years of marriage, they had no trouble agreeing on how to split the marital home or how to handle custody of their children. But when it came to figuring out how to divide more than 7,000 photographs, the picture got blurrier.

The issue in M.R. v. E.R. was finally brought into focus by Nassau County, N.Y., Supreme Court Justice Vito M. DeStefano (See Profile), who awarded the husband 75 percent and the wife 25 percent of the photos.
