The law firm Mesereau & Yu -- who defended Michael during his molestation trial in 2005 -- filed a claim on Friday against the estate, according to tmz.com.
The firm claims Michael owes them US$341,452.05 for work done between July of 2005 and February of 2006. Jackson was acquitted on 14 charges of child molestation in June 2005 -- a year and a half after he was accused.
