Robert Udashen graduated from The University of Texas School of Law in 1977 where he received the Perry Jones Award as the school's most outstanding criminal law student. Following graduation, Mr. Udashen joined the Staff Counsel for Inmates at the Texas Department of Corrections. There he represented prisoners in all types of post-conviction proceedings.
In 1979 Mr. Udashen left the Staff Counsel for Inmates to become an associate and then a partner in United States Congressman and later Texas Attorney General Jim Mattox's law firm in Dallas, Crowder & Mattox. While there, Mr. Udashen partnered with Don Crowder to successfully defend Candy Montgomery, the so-called axe murderer. The axe murder defense was recreated in a book, Evidence of Love, and in an Emmy award-winning movie, A Killing in a Small Town. CourtTV profiled the case in the fall of 2007 on the show Murder by the Book. Investigation Discovery once again profiled the case in 2014.
In 2004 Mr. Udashen teamed up with another Crowder, this time Darlina, to represent Lisa Diaz on a charge of capital murder for drowning her two children. Once again the Udashen-Crowder team was successful. Ms. Diaz was found not guilty by reason of insanity.
Mr. Udashen is now of counsel of the firm where he was partner for decades. He continues to handle state and federal criminal trials and appeals and post-conviction writ applications. Several of the post-conviction writ applications filed by Mr. Udashen have resulted in the exoneration of innocent men wrongfully convicted of various offenses.
