Michael Jackson Estate -- Executors Support Temporary Guardian for MJ's Kids

The executors of Michael Jackson's estate will go to court to support a move for a temporary guardian for Michael's 3 kids.

TMZ has learned ... papers are being drafted by the lawyer for someone who will ask the probate judge in the Estate case for the temporary guardianship. We do not know the identity of that person, however, we are told the Estate is drafting legal docs supporting the temporary guardianship.

We're told the person seeking the temporary guardianship is also filing legal docs claiming Katherine Jackson -- who is currently the legal guardian of MJ's 3 kids -- has been effectively kidnapped by Michael's siblings, and as a result they are without supervision.

Sources very familiar with the situation tell TMZ ... the executors feel responsible for protecting the kids ... since the kids are the primary beneficiaries of their father's estate. As such, the executors will support a temporary guardian for the kids.

As we previously reported, Katherine went off the radar more than a week ago leaving her grandkids behind as Janet, Jermaine, Randy, Rebbie and Tito executed a long-standing plan to convince Katherine that Michael's will was a fraud and the executors had to go.

Sources tell us ... this plan has been in the works for months, but here's the problem ... Even if the will was invalidated, MJ's brothers and sisters would get zilch because the prior will also gives them nothing.

And, although we're told Randy wants to make a move to replace the executors, that would never happen. First of all, the executors will not be removed. And second, even if they were removed, the court would never appoint someone with no background in finances.
