Is Michael Jackson's Will Fake?

Is Michael Jackson's will really a fake?

His brother Randy Jackson told Reverend Al Sharpton on MSNBC, "The evidence is right there, plain as day, that my brother was not in Los Angeles on the day that they swore, under penalty of perjury on that will, that he was. He was in New York. So, therefore, the will is fake."

The will left Michael's entire estate—estimated at $1 billion and counting—to his mother, Katherine, and three kids and zero to Michael's siblings.

The will is signed "Michael Joseph Jackson," and says it was executed on "July 7th, 2002 at 5:00 p.m., Los Angeles, CA."

But a video shows that Michael was in New York on July 7th, 2002—not in Los Angeles. He was even videotaped on a double-decker bus.  

"What it proves is that the will is fake and he cannot be in two places at one time," said Randy.

Sharpton backed up Randy's claim.

"He was, in fact, in Harlem with me that weekend," said Sharpton.

So do Michael's siblings have a case that Michael's will is fake? Not so fast.

Attorney Royal Oakes told INSIDE EDITION, "The family's chance for challenging this will really comes down to slim and none, and slim has left the building. The court has already upheld the validity of the will."

The court said the witness to the will made a simple mistake when he wrote that it was signed in Los Angeles, and that it was actually signed in New York.

The executors of the estate deny the will is fake, promising in a statement to protect Paris, Prince, and Blanket from "undue influences, bullying, [and] greed."

Oakes said, "The family's motivation is, very likely, they're in a feud with the businessmen who are running the Jackson empire. They want to challenge their authority, and may, frankly, want a settlement to cause them to just be quiet and go away."

Randy Jackson denies this has anything to do with his brother's billion dollar estate, and said on MSNBC, "This is not about money for us as a family. This is not about being left out of the will."
