Most interpreter problems in court are not caused at the hearing. They are built in at the moment of booking, when an instruction goes out for "an Arabic interpreter" with no dialect, no registration check and no papers. By the time the mismatch shows, the custody clock has run or the tribunal has risen. This checklist is the seven things worth confirming before you book.
In short
- Specify the dialect, not just "Arabic" — Yemeni and Sudanese are not interchangeable with Gulf or MSA.
- Confirm NRPSI registration and the right security clearance for the setting.
- Decide the mode early, send the papers, run a conflict check, and agree attendance notes for legal aid.
Specify the dialect — not just "Arabic"
Arabic is not one spoken language. A Yemeni client and a Gulf interpreter may share Modern Standard Arabic on paper and still misunderstand each other on the detail that decides the case. Ask your client where they are from and how they actually speak at home, and put that on the instruction. If you are not sure, say so and let the interpreter help identify it — guessing "MSA" is the single most common booking error.
Confirm NRPSI registration
The National Register of Public Service Interpreters is the benchmark UK courts expect. Full Registration means an assessed qualification, a regulator, and a complaints route if something goes wrong. Ask for the registration number and check it on the public register before the hearing — not after a challenge has been raised.
Match the security clearance to the setting
Police stations, prisons, family courts and counter-terrorism work each carry their own vetting expectations. An Enhanced DBS covers most settings; Counter Terrorist Check (CTC) clearance is what unlocks Schedule 7 examinations and Section 41 matters. Confirm the interpreter holds what the venue requires, because a clearance gap can stop a time-critical interview before it starts.
Decide remote or in-person early
Remote interpreting over Teams, Zoom, CVP or Prison Video Link is now standard for conferences, short hearings and asylum interviews, and it removes travel cost and delay. Some matters still need the room. Decide which this is at the point of instruction so you are not paying in-person rates and mileage for work that video would have handled.
Send the papers in advance
An interpreter who has seen the charge, the key statement or the bundle index can prepare dialect-specific vocabulary before the hearing. Legal terms, place names and technical material are far safer rendered when they have been looked at in advance than improvised live. A short brief — even the offence and a one-line summary — measurably improves accuracy.
Run a conflict check
In smaller dialect communities the interpreter pool is narrow, and the same names recur. Confirm the interpreter has no prior involvement with the client, the witnesses or the wider matter. A community connection that surfaces mid-hearing is both an evidential problem and an avoidable one.
Agree attendance notes for legal aid
If the matter is publicly funded, confirm at booking that the interpreter will provide a clear attendance note suited to CRM7 or CRM8. Getting the note in the right form first time avoids queries on assessment and protects recovery of the fee.
Why this matters more for Arabic than for many languages
Arabic spans a wider spread of mutually difficult dialects than most languages a UK firm books, and the rarest of them — Yemeni and Sudanese — have the smallest qualified interpreter pools in the country. That combination means the cost of a careless instruction is higher and the room for error is smaller. The seven points above are not bureaucracy; each one closes a gap that, left open, tends to surface as an adjournment, a credibility argument, or an appeal point.
Instruct directly and most of this is handled in a single exchange: one named, registered interpreter confirms dialect, clearance, mode and notes, and prepares from the papers before the hearing.
