Gave a sizable CASH retainer to a lawyer #1 who seemed like a stand-up guy, who never gave me a receipt for the money. He drew up and filed 1 paper, claims to have filed 2 papers and appeared in court once, but have no record of any of that. His services were terminated 2 weeks later and another attorney was retained. Lawyer one, using up only a small fraction of retainer fee, has yet to refund the balance of the retainer fee, saying he's behind on his billing. Months have gone by and still no refund.
What recourse do I have to collect unused portion of retainer?
