Q: When is a defendant entitled to an interpreter in Texas criminal court?

Martinez v. State: To defeat a tactical mid-trial request for an interpreter—or to preserve the right to one—practitioners must document a party's English proficiency early in the case through discovery of English-language texts, emails, and prior hearing transcripts, as Texas courts only require a litigant to understand English "well enough" to satisfy due process.

Martinez v. State

COA01 — February 24, 2026

In Martinez v. State, a defendant appealed his 50-year sentence, arguing that the trial court violated his constitutional rights by failing to appoint a Spanish-language interpreter despite a specific request for a "translation" during his adjudication hearing. The First Court of Appeals analyzed the "totality of the record," observing that the defendant had previously demonstrated functional English proficiency during his initial plea hearing, where he engaged in English colloquies and confirmed he could read and write the language "a little bit." Applying the abuse-of-discretion standard, the court held that a trial court is not required to provide the "best" interpretive services, but rather "constitutionally adequate" ones; because the record showed the defendant understood English "well enough" to participate in the proceedings and assist his counsel, no due process violation occurred.
