Interpreters are required by law in federal and state courts, in government agencies and any program that takes federal money, in hospitals and doctors’ offices that accept Medicare or Medicaid, in public schools, and in private businesses that serve the public whenever a person who is deaf, hard of hearing, or has limited English proficiency would otherwise be shut out of the interaction. The exact source of the obligation shifts from one setting to the next, but the through-line is the same: a language or communication barrier cannot be the reason someone is denied access.
Courts
The Court Interpreters Act requires federal courts to provide a qualified interpreter whenever a party or witness speaks primarily a language other than English, or has a hearing impairment that would keep them from following the proceedings or communicating with their attorney.1Office of the Law Revision Counsel. 28 U.S. Code 1827 – Interpreters in Courts of the United States It applies to criminal cases, civil cases, and proceedings initiated by the federal government. A judge can order interpreter services on their own or at either party’s request.
The court pays. Defendants and litigants are not billed for the interpreter’s time.2United States Courts. Federal Court Interpreters Most state court systems have parallel rules, though the certification programs and administrative details vary.
Government Agencies and Federally Funded Programs
Any program or agency that receives federal funding must provide meaningful language access to people with limited English proficiency. The basis is Title VI of the Civil Rights Act of 1964, which prohibits discrimination based on race, color, or national origin in federally assisted programs.3Office of the Law Revision Counsel. 42 U.S. Code 2000d – Prohibition Against Exclusion From Participation in, Denial of Benefits of, and Discrimination Under Federally Assisted Programs on Ground of Race, Color, or National Origin Because language is closely tied to national origin, federal agencies and courts have long read Title VI to require language assistance for people who cannot access services in English on their own.4U.S. Department of Justice. Title VI of the Civil Rights Act of 1964
Executive Order 13166 sharpened this obligation by directing every federal agency to build a system for giving LEP individuals meaningful access, and to make sure the organizations they fund do the same. In practice, that reaches motor vehicle departments, social services offices, housing authorities, and benefits programs.
For people who are deaf or hard of hearing, the ADA sets a separate rule for state and local governments: their communications with people who have disabilities must be as effective as their communications with everyone else. That often means a qualified sign language interpreter, though real-time captioning or written materials may be enough for simpler interactions. A government office cannot require you to bring your own interpreter, and it cannot use a minor child to interpret except during a true emergency while a qualified interpreter is being arranged.5eCFR. 28 CFR 35.160 – General
Hospitals and Medical Providers
Healthcare providers that receive federal financial assistance, which includes essentially any hospital or practice that accepts Medicare or Medicaid, must take reasonable steps to provide meaningful access to patients with limited English proficiency. This obligation comes from both Title VI and Section 1557 of the Affordable Care Act, which prohibits discrimination in covered health programs based on race, color, national origin, sex, age, or disability.6U.S. Department of Health and Human Services. Section 1557: Ensuring Meaningful Access for Individuals With Limited English Proficiency Language assistance must be free to the patient, accurate, timely, and confidential.7U.S. Department of Health and Human Services. Language Access Provisions of the Final Rule Implementing Section 1557 of the Affordable Care Act
The ADA layers on requirements for patients who are deaf or hard of hearing, regardless of whether the provider takes federal money. Written notes may work for confirming an appointment. For diagnosis, treatment options, surgical consent, or discharge instructions, providers generally need to bring in a qualified sign language interpreter.8U.S. Department of Justice. ADA Business Brief: Communicating With People Who Are Deaf or Hard of Hearing in Hospital Settings
Family Members and Children Cannot Fill the Role
Healthcare providers cannot ask a family member to interpret, and they cannot use minor children to interpret except as a brief stopgap during an emergency while a qualified interpreter is being located. Family members may lack medical vocabulary, may not interpret accurately in an emotional moment, and may have their own stake in the outcome.8U.S. Department of Justice. ADA Business Brief: Communicating With People Who Are Deaf or Hard of Hearing in Hospital Settings
Under Section 1557’s final rule, providers cannot rely on unqualified adults except during an emergency where no qualified interpreter is immediately available, or when the LEP patient privately and specifically asks that a companion interpret. Even in that second case, a qualified interpreter must be present to confirm the request is genuine and appropriate.7U.S. Department of Health and Human Services. Language Access Provisions of the Final Rule Implementing Section 1557 of the Affordable Care Act Using minor children is prohibited outright except in a true emergency with an imminent safety threat and no other option.
Public Schools
Schools that receive federal funding have overlapping duties under several statutes. Title VI requires them to take affirmative steps so that students with limited English proficiency can participate effectively in educational programs.9U.S. Department of Education. Policy Regarding Title VI Language Minority Investigations The Equal Educational Opportunities Act makes it unlawful for an educational agency to fail to take appropriate action to overcome language barriers that impede equal participation.10Office of the Law Revision Counsel. 20 U.S. Code 1703 – Denial of Equal Educational Opportunity Prohibited
These duties extend to parents. Schools must ensure that LEP parents can meaningfully participate in their children’s education, which means interpreters at parent-teacher conferences, disciplinary hearings, and enrollment meetings. Students should not be used to interpret for their own parents.
IEP Meetings
The Individuals with Disabilities Education Act specifically requires schools to take whatever action is necessary so parents understand IEP team meetings, including arranging an interpreter for parents who are deaf or whose native language is not English.11Individuals with Disabilities Education Act. 34 CFR 300.322(e) The school must provide the interpreter, not simply offer to look into one if asked.
For students with hearing, vision, or speech disabilities, ADA Title II and Section 504 of the Rehabilitation Act require schools to provide auxiliary aids so that communication is as effective as it is with nondisabled students. The specific aid depends on the student and may include a sign language interpreter or real-time captioning.12U.S. Department of Justice. Frequently Asked Questions on Effective Communication for Students With Hearing, Vision, or Speech Disabilities in Public Elementary and Secondary Schools
Private Businesses Open to the Public
Hotels, restaurants, retail stores, theaters, doctors’ offices, and law firms are considered public accommodations under ADA Title III. They must provide auxiliary aids and services, including qualified interpreters, when necessary for effective communication with people who have disabilities.13eCFR. 28 CFR 36.303 – Auxiliary Aids and Services There is no size exemption. A small business has the same obligation as a large corporation, though the analysis of what is required accounts for the business’s resources.
A business can decline a particular aid only if it would be an undue burden (significant difficulty or expense) or would fundamentally alter the nature of the goods or services. Even then, the business must still provide an alternative that ensures effective communication to the maximum extent possible.13eCFR. 28 CFR 36.303 – Auxiliary Aids and Services Undue burden is a high bar; a profitable multi-location company will struggle to argue that an interpreter fee is financially crippling.
One boundary to know: ADA Title III covers disability-related communication, not spoken-language interpretation for LEP customers. A private business that takes no federal money has no general Title VI duty to provide a Spanish or Mandarin interpreter. Private healthcare providers that accept Medicare or Medicaid are the notable exception, because Section 1557 reaches them even if they do not think of themselves as government-connected.
What Makes an Interpreter “Qualified”
The word “qualified” runs through all of these laws and means more than bilingual. A qualified interpreter can interpret effectively, accurately, and impartially, using any specialized vocabulary the situation demands. Medical vocabulary in a hospital. Legal concepts in a courtroom. Someone who speaks two languages conversationally does not automatically qualify.
Under Section 1557’s final rule, a qualified spoken-language interpreter in healthcare must be proficient in both English and the target language, interpret without changes, omissions, or additions while preserving tone and meaning, and follow accepted interpreter ethics including confidentiality.7U.S. Department of Health and Human Services. Language Access Provisions of the Final Rule Implementing Section 1557 of the Affordable Care Act Self-identifying as proficient is not enough; the provider must verify actual competence.
Video Remote Interpreting
Video remote interpreting is a permitted substitute for an in-person interpreter, but only when the technology and setup actually work. An organization using VRI must supply real-time, full-motion video and audio over a high-speed connection without lag, blur, or choppy playback; an image sharp and large enough to show the interpreter’s face, arms, hands, and fingers along with those of the person signing; clear audio; and staff trained to set up and operate the equipment.14ADA.gov. ADA Requirements: Effective Communication13eCFR. 28 CFR 36.303 – Auxiliary Aids and Services VRI should not be used when the person cannot see the screen, whether because of a vision impairment or because an injury prevents them from being positioned to face the monitor. When VRI is not working, the answer is an in-person interpreter.
If You Are Denied an Interpreter You Are Entitled To
You can file a formal complaint, and you do not need a lawyer or a filing fee. Where you file depends on the setting:
- ADA violations by government agencies or businesses: file with the U.S. Department of Justice, Civil Rights Division, through the online complaint portal or by mailing an ADA Complaint Form. DOJ may investigate, refer the matter to mediation, or forward it to another agency; review can take up to three months.15ADA.gov. File a Complaint
- Healthcare discrimination under Section 1557 or Title VI: file with the HHS Office for Civil Rights through its online complaint portal.
- Schools: file with the U.S. Department of Education’s Office for Civil Rights, which handles Title VI, Section 504, and ADA complaints in educational settings.
Federal complaint deadlines usually run 180 days from the discriminatory act, though the window varies by agency, so do not wait. Document the denial: the date, the time, the name of anyone you spoke with, exactly what you asked for, and the response you received. A written request creates a cleaner record than a verbal one. If the agency finds a violation, remedies can range from ordering the organization to change its practices to financial penalties in serious cases. Individuals also bring private lawsuits under the ADA and Section 1557, where courts can award injunctive relief and in some cases damages.
