Language access rules in Kentucky

Court interpreter program: Kentucky Court of Justice, Administrative Office of the Courts (AOC), Office of Language Access, which arranges and provides interpreters for court proceedings and direct court services statewide under Part IX of the Administrative Procedures of the Court of Justice, the Language Access Plan and Procedures (Supreme Court Order 2017-15, effective January 1, 2018).
Court-certified languages: The AOC credentials spoken-language interpreters as certified, provisional, or registered under its Certification Policy for Spoken Language Interpreters, and its interpreter directory lists certified interpreters in Spanish, Arabic, Bosnian, Croatian, Serbian, Montenegrin, Cantonese, Mandarin, French, Haitian Creole, Korean, Portuguese, Russian, Somali, Vietnamese, and American Sign Language. Interpreters for deaf and hard of hearing people must also be licensed by the state.
The rule: KRS 30A.410 requires the court in any criminal or civil matter to appoint a qualified interpreter, paid out of the State Treasury, for parties, jurors, and witnesses who cannot communicate in English, who are deaf or hard of hearing, or who have another disability that would prevent them from understanding the proceedings; under KRS 30A.415 the Court of Justice pays for interpreting at court appearances, and KRS 30A.405 directs the Supreme Court to set interpreter standards, administered by the AOC.
Interpreters at arrest: KRS 30A.400 requires an interpreter before any interrogation or statement of a person in police custody or under arrest whom the court finds meets the KRS 30A.410 criteria, and that person's statement to law enforcement may be used as evidence against them only if made in the presence of a qualified interpreter.
Court team interpreting: Section 8 of the Kentucky Court of Justice Language Access Plan requires a team of two interpreters for trials, grand jury proceedings, and interpreting for jurors, and calls for a team of two when interpretation runs two or more hours without breaks.
State agency access for deaf and hard of hearing people: KRS 12.290 requires every department, program cabinet, and administrative body of state government to adopt administrative regulations making all services accessible to deaf or hard of hearing people, including interpreter services for anyone who makes a timely request.
Child and family services LEP policy: Kentucky Cabinet for Health and Family Services Standards of Practice G1.14 (effective June 18, 2026) requires staff to tell clients with limited English proficiency of their right to a Cabinet-provided interpreter free of charge, prohibits using a child as an interpreter, and states that Google Translate and similar apps are not an acceptable substitute for in-person interpreters.
Interpreter licensure: Since July 1, 2003, KRS 309.301 has barred anyone from practicing or representing themselves as an interpreter, as defined in KRS 309.300, without a license under KRS 309.300 to 309.319 (Kentucky's licensing law for interpreters for deaf and hard of hearing people), with exemptions for nonresidents working fewer than 20 days a year, religious activities, unpaid volunteers, emergencies, and supervised interpreting students.
Official language: KRS 2.013, enacted in 1984, designates English as the official state language of Kentucky; the one-sentence statute contains no restriction on translation or interpreting, and the court interpreter statutes above operate alongside it.
Court document translation: Under the Language Access Plan, the courts' Office of Translation Services translates only vital court documents, while parties, attorneys, and witnesses must supply their own English translations of foreign-language documents and audio or video evidence.
