Real-time legal interpreting is now an established requirement across courts, tribunals and legal services, particularly as remote and hybrid hearings become routine. In England and Wales, HMCTS has set out an approach that supports remote participation in hearings, reflecting a sustained operational shift rather than a temporary measure. In this environment, legal teams increasingly need interpreting that works reliably across video links, secure audio channels and time-pressured case management.
This article explains the practical realities of real-time legal interpreting, focusing on technology, accuracy, and constraints that affect outcomes. It is written for solicitors, in-house counsel, compliance teams, and professional service users who need court interpreting, remote interpreting, or telephone interpreting delivered to a standard that is defensible and repeatable.
Technology in legal interpreting: what “real time” actually means
“Real time” refers to interpreting delivered live—usually in consecutive, simultaneous, or whispered modes—while a hearing, conference, interview or consultation is taking place. In legal settings this may occur in person, but increasingly via video platforms integrated into court and tribunal processes. The Law Society notes the direction of travel toward video hearing services and features such as simultaneous interpreting for users who need a translator, underscoring the need for interpreters who can operate effectively within modern hearing infrastructure.
Technology can extend access—supporting parties who cannot attend in person and helping manage listing pressures—but it also creates new points of failure. Judicial and policy materials on remote hearings highlight the importance of open justice and the practicalities of remote participation, while independent reviews of remote hearings identify recurring problems such as unstable connections and variable audio quality.
Accuracy: legal risk is rarely caused by “general” language mistakes
Accuracy in legal interpreting is not limited to literal meaning. It includes:
- faithful transfer of legal concepts and procedural language
- correct handling of numbers, dates and names
- consistent management of register (formal/informal speech) and tone
- accurate treatment of turn-taking, interruptions and overlapping speech
International good practice is increasingly expressed through standards. ISO 18841 sets general requirements and recommendations for interpreting services. For legal interpreting specifically, ISO 20228 describes principles and practices for legal settings and specifies competencies for legal interpreters, reflecting the specialised demands of courts, police and legal consultations.
In parallel, legal rights frameworks reinforce why accuracy is not optional. EU law on the right to interpreting and translation in criminal proceedings requires interpreting to be provided so that suspected or accused persons can understand and participate, with services provided free of charge where required.
Practical constraints that affect performance in remote and hybrid hearings
1) Audio quality and latency
Remote interpreting is sensitive to sound clarity. Where audio drops, clips or distorts, the interpreter may be forced to infer content—an unacceptable position in legal contexts. Remote hearings reviews record repeated issues with connection quality and stability, including examples of participants being disconnected.
Latency is a separate constraint: even a short delay changes turn-taking, increases the likelihood of overlap, and raises the interpreter’s workload.
2) Cognitive load and fatigue
Peer-reviewed research and large literature syntheses consistently identify cognitive load as a central constraint in distance interpreting. A synthetic review of distance interpreting literature describes how technology-mediated conditions shape cognitive demand and performance pressures. More recent research continues to examine how remote simultaneous interpreting conditions affect accuracy under increased cognitive load.
Practically, this means that interpreter scheduling, breaks, and realistic time estimates are not “nice extras”: they are risk controls.
3) Visual limitations and evidential detail
Legal interpreting is supported by visual cues (speaker identification, gestures, exhibits, courtroom dynamics). Video links can reduce those cues, especially where camera framing is poor or multiple participants share a single audio channel. Research on video-mediated court interpreting discusses how interpreters must manage additional demands created by remote configurations.
4) Confidentiality and secure communications
Legal interpreting often involves privileged discussions. A remote hearing format requires secure channels, clear rules on who can hear which parts of the hearing, and appropriate handling of interpreter access to documents and bundles.
Where “technology” is helpful and where it is not
Speech technology (including automatic speech recognition) is improving and can support workflow, but it should not be treated as a substitute for a qualified legal interpreter in live proceedings. Performance is often described using objective measures such as word error rate (WER), which counts substitutions, deletions and insertions relative to a reference transcript. Even when systems perform well in controlled conditions, legal environments introduce accents, multiple speakers, interruptions, and specialised terms—conditions that amplify risk.
A defensible approach is therefore to treat technology as a support tool—improving logistics, access and documentation—while keeping human interpreting as the primary mechanism for accuracy, accountability and professional ethics.
An IMD Translation approach aligned with professional services expectations
IMD Translation provides interpreting services for professional service firms and legal contexts, with processes designed for reliability, confidentiality and controlled delivery.
For organisations requiring real-time legal interpreting that can stand up to court scrutiny, the practical focus should be: appropriate interpreter competence for the legal setting, robust remote-hearing logistics, and a documented quality process consistent with recognised standards.

Conclusion
Real-Time Legal Interpreting: Technology, Accuracy, and Practical Constraints is best addressed as a managed professional service rather than an informal add-on to a hearing link. Remote participation has become a standard feature of court and tribunal practice, but it introduces technical and human-factors risks that directly affect understanding and procedural fairness. Using recognised interpreting standards, evidence-based awareness of cognitive constraints, and quality-managed delivery provides the clearest route to accurate, practical and defensible interpreting in legal settings.
