Michael Jackson's father is seeking an allowance from the late singer's estate to help cover his monthly expenses, which exceed $15,000 US, according to court documents filed Friday.

The request, which seeking an unspecified amount for Joe Jackson was filed in Los Angeles by lawyer Brian Oxman, who said there was no apparent reason for the administrators of the estate to not seek an allowance for the 81-year-old.

Michael Jackson's 2002 will only called for money to be paid to his mother, Katherine, his three young children, and various charities.

A judge has approved more than $26,000 US in payments to Katherine Jackson each month and a $60,000 US monthly payment for the care of Jackson's children.

The latest court documents say Joe Jackson receives a $1,700 US monthly Social Security payment and had relied on his son for support for many years. He suffers from diabetes and had a stroke in 1998, the filing states.

"He does not have a regular or steady source of income, and he was dependent upon the money provided by his son, Michael Jackson, through his wife, Katherine Jackson, for his support," the filing states.

An itemized list of expenses says Joe Jackson spends $1,200 a month on rent for his Las Vegas home; $2,500 to eat out; $1,000 on entertainment, gifts and vacations; $2,000 on air travel and $3,000 on hotels.

A phone message left for Oxman was not immediately returned.

James Bates, a spokesman for the administrators of Jackson's estate, did not immediately respond to an email seeking comment.

A judge denied Joe Jackson's petition for an expedited hearing on the matter and his request to file the motion under seal.
