Weiland hired attorneys from G&M Law in 2013 after he was sued by his former Stone Temple Pilots bandmates for allegedly "hijacking" their tour by showing up late for performances and missing promotional gigs.

The singer was kicked out of the band, and countersued the remaining members in a bid to ban them from using the name of Stone Temple Pilots.

He dropped his attorneys last year (14), and now, according to documents obtained by TMZ.com, lawyers at G&M Law have served their former client with legal papers alleging Weiland owes them fees from both cases in 2013.

They claim they were cooperative as Weiland transitioned from their firm to another one as his legal troubles continued, but still failed to receive any compensation, totaling more than $50,000 (£31,250).
