They have those 4 documents but the Jacksons proved that they're forged. If they were valid documents, his estate wouldn't have to make that laughable excuse for why it had Mike's signature on that date. The way the Kat situation played out shows that the elders of the Jackson family knows all the truth while the younger members are being brats, attention whores, and disrespectful. Janet obviously didn't care about it until it was affecting her mom, and I find it funny how all of a sudden "insiders" are releasing crap to TMZ making Janet seem broke and money hungry (let's not forget Janet's also jealous of her niece whose career might just be summed up as "MJ's daughter"). They're better off stepping down right now, because it's only gonna get worse as time goes by.
