The observer has been there for the past week at the recommendation of Mel's legal team. Not only will the supervisor serve as a witness in case Oksana brings new allegations against him, but he can hurry the investigation by the L.A. County Department of Children and Family Services.
Mel's lawyer's picked out the observer, who is credentialed in family law, themselves. He is providing regular updated to Family Service.
Hope he plans on having supervised visitation for a LONG time! It's gonna take a lot to trust him after this shiz.
