In his will, written in 2002 and filed in court days after his June 25 death, Jackson lists Branca and McClain as executors of an estate valued at more than $500 million.
The two men have been named special administrators of Jackson's estate until Aug. 3, when they will return to court with Katherine, who had previously requested to become the interim executor of her son's estate.
Jackson's will placed his estate into a trust, that gives 40 percent of his wealth to his mother, 40 percent to his three children and 20 percent to charities.
Katherine currently has temporary guardianship of Jackson's three children—Prince Michael, 12; Paris Michael Katherine, 11; and Prince Michael II, nicknamed Blanket, 7. According to the will, Jackson wanted his mother to take care of his children. Jackson's father, Joe, and Debbie Rowe, Jackson's ex-wife and biological mother of his two oldest children, were left out of the will.
Katherine Jackson and Rowe are reportedly working out a deal regarding custody of the children. Though Katherine has custody, Rowe could ask a court to make her the children's guardian. Whoever gets custody will presumably be given a fair amount of money from the trust to take care of them.
When Jackson died, the pop star was $331 million in debt. The Associated Press reported he claimed $576.6 million in assets as of March 31, 2007. Among Jackson's assets is a 50 percent share in the Sony/ATV catalog that includes rights to 251 Beatles songs, worth $390.6 million.
Gunned down by his girlfriend on July 4, former Titans quarterback Steve McNair left no will or directions on how to distribute his estate.
Complicating matters further, no one is entirely sure how much McNair was worth, or even how many children he really had.
Though his total worth is still being established, it is known that he earned over $75 million in contracts over a 13-year career.
McNair's wife, Mechelle, was granted the right to control the fallen quarterback's estate by a Davidson County, Tenn., judge after filing an emergency petition. She has 60 days to determine her late husband's worth.
A probate court named Mechelle McNair and her sons, Tyler, 11, and Trenton, 6, as the heirs to the unvalued estate, according to newspaper the Tennessean.
But McNair also seems to have two older sons, born out of wedlock to another woman -- Steven L. McNair Jr., a high-school senior and Steven O'Brien Koran McNair, 15.
For now, however, there is no proof of paternity for the two older boys. McNair was reportedly paying $500 a month in child support of the 15-year-old boy.
Though neither of the older children has yet claimed inheritance, "I am sure that in due course there will be a discussion with everyone who has an interest in the estate," David Callahan, Mechelle McNair's attorney, told the Tennessean. "At this point, there has not been any formal discussion."
James Brown's estate spent over two years in limbo following his death on Christmas Day 2006.
Brown's adult children claimed his widow Tomi Rae Hynie Brown was owed nothing because she was married to another man when she wed the singer in 2001.
Brown left behind an estate valued at $80-$100 million, though no number has been officially released, according to the AP. However, a sizable debt left the icon's legacy in jeopardy.
