Dallas Post-Conviction Attorney
When Something Went Wrong With the Case
Your family sees the missing piece.
Does Texas law provide a way to address it?
Maybe the trial lawyer never interviewed a witness your family identified. Maybe records you handed over were never used, or an expert was never consulted. A conviction in Dallas County can leave a family asking a hard question:
Did the defense miss something that could have changed the case?
You do not need to decide whether the legal label is “ineffective assistance of counsel” before contacting a post-conviction attorney. Start with the specific event: what the lawyer was told, what the lawyer did or did not do, and what the missing information would have shown. From there, an attorney can assess the trial record, information outside it, and the case’s procedural history.
Blizzard & Zimmerman Attorneys is based in Abilene and represents people in post-conviction matters across Texas, including convictions from Dallas and the surrounding metro area. Our team, led by Sarah Durham, helps families across the state distinguish a troubling outcome from a claim that can be supported with facts and raised through an available legal procedure.

The lawyer didn’t investigate.
What would an attorney need to know?
A family may have a detailed account of what went wrong without having the documents needed to prove it. For example, “the lawyer never called our witness” leads to several important questions:
- What would the witness have said, and how do we know?
- Did counsel know about that witness before the plea or trial?
- Was the witness available and credible?
- Does the trial record show a reason the testimony was not presented?
- How might the missing information have affected the outcome?
The same approach applies to an unfiled motion, unchallenged evidence, a missing expert, plea advice, or sentencing preparation. A missed step alone does not establish ineffective assistance. The legal review must examine counsel’s conduct and the significance of the alleged error in the context of the whole case.

Frequently Asked Questions about Dallas post-conviction
Yes, a family member can make an inquiry and help gather records even if the conviction occurred in Dallas and the person is now held in another part of Texas. Representation and communication with the incarcerated person must be arranged for the particular case.
Not automatically. However, the witness’s proposed testimony, counsel’s knowledge and choices, available proof, and the legal effect of the omission all need review.
A denied appeal does not settle every possible post-conviction question. The available procedures depend on the conviction, appeal history, prior applications, and the particular claim.
