ET is sitting down with a custody expert who's weighing in on what he thinks may happen to Michael Jackson's three young children.

Mike Kretzmer, a family law attorney specializing in child custody, tells ET what may happen at an upcoming July 20 custody hearing. Kretzmer works at the firm of Kolodny & Anteau, a leading family law practice in Los Angeles that has handled many celebrity divorces.

The guardianship hearing was expected to take place on July 13 but was postponed until Monday, July 20. According to the court, Katherine Jackson and Debbie Rowe requested that the hearing concerning the custody of Michael "Prince," Paris-Michael, and Prince "Blanket" be postponed a week. All previous orders will remain in effect until the 20th, and Katherine Jackson will remain the children's temporary guardian until then.
