Sandra Bullock's ex-husband is being sued by his former divorce lawyers.

Jesse James, whose split from the 'Gravity' actress was finalised in 2010 after he cheated on her with multiple women, reportedly owes the attorneys that represented him $100,000 in unpaid bills but they are seeking more than $500,000 in damages.

California law firm Yanny & Smith filed a lawsuit against the 44-year-old TV personality, claiming he agreed to pay them a ''fixed monthly retainer'' in March 2009, shortly after his affair with Michelle McGee was exposed.

The lawyers ''provided legal services to'' Jesse, who owns custom motorcycle business West Coast Choppers in Texas, until July 23, 2012, including ''overseeing the resolution of dissolution of'' his marriage to the Oscar-winning actress.

According to court documents, obtained by gossip website, they also successfully defended Jesse ''through trial and post-trial motions in a suit concerning an alleged joint venture involving a proposed clothing line to be sold at Wal-Mart where 12 to 14 million dollars of compensatory damages were being demanded of James.''

They also allegedly defended Jesse when he was sued by a paparazzo and provided ''representation in other adversarial proceedings including allegations of sexual harassment, disputes regarding defendant's failure to pay monies due to other people, etc.''

The lawyers claim that while ''invoices were generated periodically and sent to defendant,'' they were never paid and are seeking $500,000 to cover the bills, interest and damages.
