/*Joe Jackson*/ filed the lawsuit on Friday against /*Dr. Conrad Murray*/, who has been charged with involuntary manslaughter in the singer's death.
The Jackson family patriarch was omitted from his son's will, but in November asked to receive a $15,000 a month allowance to pay his monthly expenses.
Joe Jackson's filing indicates he may renew his request for a stipend later if necessary.
