Jon Cox

A tenacious, accessible and trustworthy criminal defense and family law attorney who advocates for clients

A former Boise State University & NFL football player, Cox Law Firm founder Jon R. Cox continues to exhibit a winner’s mentality in the practice of law. He has a reputation for fighting on behalf of his firm’s clients, backed by a 21-year track record of success.

But it’s teamwork that Jon prizes above all else. He works closely with each client in a manner that builds trust and confidence. His affable demeanor and fearless approach to litigation have resulted in positive outcomes and satisfied clients.

When handling criminal cases, Jon Cox works to protect clients’ rights above all else. By having a reputation with prosecutors of being unafraid to take his client’s case to jury trial, Jon is able to minimize penalties by achieving downgraded charges through plea bargains, including many rehabilitation-focused sentences. Other times, through meticulous investigation, he’s able to find and prove reason for cases to be completely dismissed.

Jon’s standing in the Boise legal community speaks for itself: He was named to the National Trial Lawyers Top 100 Trial Lawyers and is the first private practice attorney to be awarded the Klaus Wiebe “Cockroach” award. That award is given by the Idaho Association of Criminal Defense Lawyers (IACDL) to the lawyer who’s had the most jury trials in a year for two years in a row.
