Meet Jim Erickson: Senior Trial Attorney, Barton & Associates, Attorneys at Law

Texas State Bar Number: 06641000 | Licensed: May 10, 1985

Who is Jim Erickson, and What Does 40 Years of Criminal Defense Experience Mean for Your Case?

Most attorneys who have been practicing law for four decades have a long list of cases behind them. Jim Erickson has something rarer—a verified record that stands alone in the history of Texas criminal defense. He is the Senior Trial Attorney at Barton & Associates, Attorneys at Law, and he has been fighting for defendants in Texas courtrooms since May 10, 1985. Over the course of his career, he has handled several thousand criminal cases, appeared in courts across more than 66 Texas counties, tried over 250 cases to a jury verdict, and secured one of the most extraordinary outcomes in the history of Texas criminal law: only the third Not Guilty by Reason of Insanity jury verdict ever returned in the State of Texas. That verdict alone—in a state where the insanity defense is raised in fewer than one percent of criminal cases and almost never succeeds before a jury—places Jim Erickson in a category that very few criminal defense attorneys in this country can occupy. When a prospective client asks whether their attorney has seen cases like theirs before, Jim Erickson’s answer is almost certainly yes—and his track record shows what he has done with them.

A Career Record That Speaks for Itself

Numbers matter in criminal defense, but context matters more. Over 250 jury trials does not mean 250 plea agreements that went sideways—it means 250 cases where Jim Erickson stood before a jury, presented a defense and competed for a verdict. That volume of actual trial experience is exceptionally rare. Most defense attorneys in Texas try fewer than a handful of cases to verdict in their entire careers. The economics and culture of the criminal justice system push heavily toward pleas and settlements, and attorneys who rarely try cases lose the courtroom instincts that only repetition builds. Jim Erickson has never lost those instincts. After more than four decades of continuous litigation across 66 Texas counties, he walks into any courtroom in this state as someone the system recognizes—someone who has been there before, who knows how judges think, how prosecutors approach different fact patterns, and how Texas juries respond to different kinds of evidence and argument. That institutional knowledge is not something that can be studied or simulated. It is built one case at a time over decades, and Jim Erickson has built more of it than nearly any criminal defense attorney in Texas.

The Landmark Verdict: The Third Not Guilty by Reason of Insanity Jury Verdict in Texas History

To understand why Jim Erickson’s Not Guilty by Reason of Insanity verdict is so significant, it helps to understand exactly how rare this outcome is. The insanity defense in Texas is governed by Texas Penal Code Section 8.01, which establishes that it is an affirmative defense to prosecution that, at the time of the conduct charged, the actor—as a result of severe mental disease or defect—did not know that his or her conduct was wrong. Raising this defense requires the defendant to prove insanity by a preponderance of the evidence, typically through forensic psychiatric testimony. It is raised in fewer than one percent of all criminal cases in Texas. Of those cases, successful jury verdicts are extraordinarily rare—not just because the legal standard is demanding, but because Texas juries are deeply skeptical of the insanity defense, often believing that a Not Guilty by Reason of Insanity verdict means the defendant will simply be released. Convincing a Texas jury to return this verdict requires an attorney who can manage psychiatric expert testimony, dismantle the prosecution’s counter-narrative, navigate the court’s instructions on consequences, and persuade a room of ordinary Texans to trust a legal outcome that runs against every instinct they carry into the courtroom. Jim Erickson has done it. He has secured the third such verdict ever returned by a Texas jury—a distinction that is not ceremonial and cannot be replicated or purchased. It is the result of one of the most difficult legal performances that Texas criminal defense practice demands, and it stands as the defining achievement of an already exceptional career.

Statewide Reach: 66 Counties and Counting

Most criminal defense attorneys build their practice in a single jurisdiction. They know their local courts, their local prosecutors, and their local judges—and that local knowledge is valuable. Jim Erickson’s reach extends far beyond any single county. He has appeared in courts across more than 66 Texas counties, spanning the length and breadth of the state. That statewide footprint means that when a client faces charges in a court outside of Travis County—whether in a rural West Texas jurisdiction, a Gulf Coast court, or a North Texas felony district—Jim Erickson is not walking in blind. He has navigated Texas courtrooms in jurisdictions that most San Antonio attorneys have never set foot in, giving him an understanding of how criminal practice varies across the state that very few defense attorneys possess. For clients facing multi-county cases, cases transferred between jurisdictions, or charges in a court far from home, that experience is not a luxury—it is a necessity.

What Types of Cases Has Jim Erickson Handled?

Jim Erickson’s case history covers the full spectrum of Texas criminal law, from misdemeanor matters to the most serious felony charges the Penal Code recognizes. His several thousand cases include:

• Capital Murder defense — the most serious criminal charge in Texas, carrying the possibility of the death penalty or life without parole
• Murder and homicide defense — including cases involving complex forensic evidence, eyewitness identification issues, and self-defense claims
• Robbery and aggravated robbery — including cases involving weapons and serious bodily injury allegations
• Assault with a deadly weapon and aggravated assault
• Drug offenses — including possession, delivery, and manufacture of controlled substances at all weight ranges and penalty group classifications
• DWI and felony DWI defense — including intoxication assault and intoxication manslaughter
• Sex crimes defense
• Federal criminal defense
• Cases requiring the insanity defense and competency proceedings under Texas Code of Criminal Procedure Chapter 46B and 46C

That range is not incidental. It reflects an attorney who has spent forty years saying yes to clients who had nowhere else to turn—who faced charges that most attorneys would not touch, in jurisdictions that required real statewide knowledge, in cases where the stakes were nothing less than a person’s freedom or their life.
