Know the roster tiers
Minnesota maintains a State Court Interpreter Roster covering the state's most-requested spoken languages — 16 of them under formal testing (Minnesota Judicial Branch, mncourts.gov) — across certified and noncertified tiers. For most proceedings, courts must make a diligent effort to appoint a certified interpreter before going down the tiers, and the standard rises with the stakes of the matter.
- Prefer certified-tier interpreters for evidentiary proceedings
- Document diligent-search efforts when certified is unavailable
- Match the tier to the proceeding's stakes
Certification by language
Certified-tier coverage is deepest for Spanish — which alone accounts for roughly 62 percent of the limited-English-proficient population nationwide (U.S. Census Bureau, census.gov) — and exists for a number of other languages, while many high-demand Minnesota languages — Somali, Karen, Oromo, Karenni — have limited or no certified pool. Plan early for these: demand is real, but the certified supply is thin and requires lead time to secure.
- Confirm whether a certified interpreter exists for the language at all
- For thin-supply languages, build in extra scheduling lead time
- Capture the qualification basis on the record
Impartiality and conflicts
Court interpreters must be neutral. Minnesota's Code of Professional Responsibility for court interpreters requires impartiality and complete, accurate interpretation (Minnesota Judicial Branch, mncourts.gov). Screen for conflicts of interest, avoid interpreters with a relationship to any party, and ensure the interpreter understands the duty of complete and accurate interpretation without summarizing or advising.
Plan proceedings around demand
For the most-requested languages, schedule interpreters as early as you schedule the proceeding itself. With more than one in nine Minnesotans speaking a language other than English at home (U.S. Census Bureau via Minnesota Compass, mncompass.org), demand is steady, and treating interpreter sourcing as a late logistics step is the most common cause of continuances in multilingual matters.
Key takeaways
- Default to the certified tier and document diligent search
- Verify whether certified coverage exists for the specific language
- Screen every interpreter for conflicts and impartiality
- Book interpreters for thin-supply languages as early as possible
