RMO secures $2.5 million verdict despite fraudster’s court dodging

LOS ANGELES, May 6, 2022 /PRNewswire/ — A fraudster’s attempt to strategically avoid liability and litigation have ended after six years with a $2.5 million judgment.

The plaintiff, represented by national probate litigation law firm RMO LLP, initially filed claims in 2017 as part of a case involving fraud, including tax avoidance. While the matter was initially slated as an arbitration, the defendant (and the multiple shell companies through which they operate) failed to honor contractual terms by refusing to pay the arbitrator. This forced cancelation of the arbitration and shifted the matter to state court.
