NRPSI Registration Explained: A Solicitor's Guide to Hiring a Qualified Arabic Interpreter

Before you instruct an interpreter for a police interview, a Crown Court trial, or a family court hearing, there is one credential that does more work than any other to protect your client and your case.

What NRPSI is — and what it isn't

The National Register of Public Service Interpreters (NRPSI) is the UK's independent voluntary regulator of professional interpreters working in the public sector. It maintains a public, searchable register of qualified, security-cleared, and accountable interpreters covering around 100 languages.

NRPSI is not a qualification, and it is not an agency. It is a regulator. To be admitted to the Register, an interpreter must:

• Hold an approved qualification such as the Diploma in Public Service Interpreting (DPSI) in Law, or equivalent;
• Provide evidence of supervised public service interpreting practice;
• Hold a valid security clearance (Enhanced DBS minimum, often CTC or higher);
• Carry professional indemnity insurance;
• Sign up to the NRPSI Code of Professional Conduct, enforceable through a formal complaints procedure.

That last point is the one most often missed. An unregistered interpreter, however fluent, sits outside any formal accountability structure.

Why this matters in practice

1. Criminal defence and police interviews under PACE

Codes of Practice attached to the Police and Criminal Evidence Act require an interpreter where a suspect does not have sufficient command of English. Courts expect that interpreter to be on the NRPSI Register or hold an equivalent credential. Relying on an unregistered stand-in creates a clear line of attack on the integrity of the interview record.

2. Family proceedings, including FGM Protection Orders

In family court safeguarding matters — FGM Protection Orders, forced marriage, care proceedings with vulnerable respondents — the interpreter is part of how the court hears the parties. Dialect matters: a Yemeni respondent does not always understand a Modern Standard Arabic interpreter.

3. Asylum and Home Office matters

Home Office substantive interviews and tribunal appeals have specific interpreter requirements. NRPSI registration combined with the relevant clearance (typically CTC) is the cleanest way to demonstrate competence on the record.

How to verify NRPSI registration in under a minute

1. Go to www.nrpsi.org.uk.
2. Search by surname or registration number.

The result shows registered language(s), status (Full or Interim), area, and clearances. If someone claims NRPSI but doesn't appear, treat that as a serious red flag.

Common questions from solicitors

"Does the agency I already use only send NRPSI interpreters?"

Often, no. Many panels mix NRPSI-registered interpreters with DPSI-qualified but unregistered linguists. Ask the agency to confirm registration and number on the booking form, and verify it yourself.

"Can I instruct an interpreter directly?"

Yes. Direct instruction is increasingly common where a firm wants continuity, tighter conflict-checking, or dialect specificity.

"What about translation of documents?"

Translation and interpreting are distinct disciplines. NRPSI is the register for spoken-word interpreters. For written translation of evidence — witness statements, statement of truth, affidavits, identity documents — a qualified translator should be instructed. A translator's statement of truth confirming the accuracy of the translation is standard practice. Where sworn or notary certification is required (for example by HMCTS or the Home Office), that is arranged separately.
