A federal judge in Texas has granted a temporary restraining order against a former Edward Jones broker who left the firm to set up shop next door with Raymond James.

Russell Ryon Riggan managed $500 million in assets at Edward Jones in Snyder, Texas, and serviced 1,582 households, according to the firm’s complaint and filing for the restraining order, which was ordered effective on Monday afternoon. The firm says that around May 18, Riggan both resigned without notice and locked Edward Jones personnel out of its own 1,200 square foot office space, blocking them from access to hard drives, computers and client files, since Riggan owned the building that housed it through an LLC. He also took the furniture, the company said.

“Not only did the defendant resign without notice and immediately begin working for a competitor, Raymond James, he also physically locked out Edward Jones from the office space in Edward Jones’ Snyder, Texas, branch” on College Avenue. The company says Riggan held on to confidential customer information and trade secrets that it owns and used it to unlawfully lure Edward Jones customers by promising them lower fee accounts.

“Unbelievably, Riggan erected a modular building, now being used as his new Raymond James office, abutting the Edward Jones office at issue,” said the complaint.

These moves put him in breach of his employment agreement, not to mention the lease agreement, the company claims. Riggan had been with Edward Jones for 15 years, according to the court documents.

According to Judge James Wesley Hendrix, U.S. District Court judge for the Northern District of Texas, Riggan’s employment agreement recognized that the documents containing confidential trade secrets were Edward Jones property, and also protected the company in its office lease. He also said that the company could likely succeed in its breach of contract claim, which was given as one of the reasons for granting the TRO. Edward Jones says customers told the company that Riggan was soliciting clients to move to Raymond James both before and after he resigned, promising them they could save 10% on fee-based accounts. However, the judge also said that the furniture likely belonged to Riggan and the party in the lease conflict should instead be the LLC, not Riggan himself.

As part of the restraining order, Riggan must stop soliciting Edward Jones’s customers to move their accounts to Raymond James and abide by the confidentiality and non-solicit clauses in his employment agreement.

Riggan said in an objection to the restraining order that client documents remained in the offices of Edward Jones, and that customer lists that he was allowed to print before leaving the company were not taken from the office and were no longer in his possession. Riggan argued that it was Edward Jones who changed the locks.

Edward Jones is known for single-broker offices in smaller markets and says on its website it has 15,000 branch locations.

Riggan’s LinkedIn profile says he’s currently employed with Talent Financial Services with Raymond James. A short 2015 profile in Investment News said Riggan worked with his father. But Tim Riggan, who in the past shared office space with Russell at a different address, said when reached only that he continues to work for Edward Jones.

Russell Riggan’s attorney did not return a phone call seeking comment.

A motion for a broader motion for preliminary injunction is set for June 7 and the two parties are also seeking arbitration through the Financial Industry Regulatory Authority.
