The Mistake in Michael Jackson's Will

Michael Jackson's 2002 will has a mistake in it, TMZ has learned -- but it looks like a case of no harm, no foul.

As we first reported, according to the will -- dated July 7, 2002 -- it was signed in Los Angeles. But Randy Jackson told TMZ Michael was in New York City on that date.

Randy thinks the signature on Michael's will is a forgery. But Howard Weitzman, the lawyer for the estate, tells TMZ the signature is valid and the witnesses saw Jackson put pen to paper.

We've now confirmed Jackson definitely signed the will in New York City on 7-7-02. So the reference to Los Angeles is clearly a mistake.

Our sources say the person who wrote "Los Angeles" is one of the witnesses to the will and simply forgot where he was.

This mistake will not invalidate the will. Ironically, if the will were declared invalid, the prior 1997 will would be probated. Just like the 2002 will, the 1997 will creates a trust. We've learned the '97 trust -- just like the 2002 trust -- leaves the same percentage to the same people: Katherine Jackson gets 40% for her lifetime, MJ's kids get 40% and the remaining 20% goes to charity.

By the way ... guess who one of the executors is in the '97 will? John Branca.
