Joe Jackson claims there was "no justification" for him to be excluded from getting money from Michael Jackson's estate ... and now he's asking a judge to grant him a monthly allowance.
Joe just filed papers in L.A. County Superior Court, claiming he's "entitled to his own independent family allowance."
In the docs, Leonard Rowe -- a guy who claims to have been MJ's manager -- says Michael used to give his mother Katherine up to $60,000 a month to live on, and that Michael instructed her to give half of it to Joe.
Joe claims Michael's estate has "earned more than $100 million dollars in the first seven (7) weeks following Michael Jackson's death" and is "well able to afford a family allowance for Joe Jackson."
Joe says he has $15,425 in total monthly expenses, including the following:
-- $2,500 eating out
-- $2,000 for air travel
-- $3,000 for hotel bills
-- $1,000 for groceries
-- $1,200 for rent
-- $50 in charitable contributions
UPDATE -- Howard Weitzman, one of the attorneys the Special Administrators for Michael Jackson's Estate, tells TMZ: "The Special Administrators have been made aware that Joe Jackson filed papers asking to be paid a family allowance from the Estate. It was quite surprising to learn of the request. Mr. Jackson's Petition will be considered as are all requests for money from Michael's Estate."
