Even though Michael Jackson's father was not included as a beneficiary in his will or trust, it hasn't stopped Joe Jackson from trying to intercede in the legal proceedings surrounding the estate. First, he asked the judge to remove estate executors John Branca and John McClain.
The probate judge dismissed his claims, saying he lacked "standing" in the estate because he was not a beneficiary. In other words, he did not have enough of a financial interest in the estate to be able to legally complain about who was in charge.
Recently, Joe Jackson filed an appeal of that decision, arguing that he was financially dependent on his son while he was alive, so he did have enough of an interest to attack the executors.
