Shlain had three children with Carole Lewis Jaffe: Kimberly Brooks (who is married to actor/comedian Albert Brooks), Jordan L. Shlain, and Tiffany Shlain, filmmaker and founder of the Webby Awards.

After he and Carole divorced, Shlain met and married his second wife, Superior Court Judge Ina Levin Gyemant.
