Michael Jackson's family wants a judge to delay designating two men listed in the pop superstar's will as temporary administrators of his estate so that they can look deeper into his affairs, a person close to the family said Sunday. The family also wants the additional time to wait and see if another will emerges, as well as to accommodate Jackson's memorial service Tuesday, said the person, who was not authorized to speak publicly and requested anonymity.

A judge on Thursday delayed a hearing on who should have custody of Jackson's three children, making Monday's hearing entirely about the singer's fortune. A temporary administrator would also have the power to take over numerous lawsuits pending against Jackson, including a $44 million federal claim filed by former publicist Raymone Bain, two lawsuits filed by “Thriller” director John Landis, and another one filed by “Thriller” co
