Conference interpreters: professional indemnity and confidentiality

What the exposure actually is

Simultaneous interpreting is performed live, at speed, without the opportunity to check a term against a reference or ask a colleague. Consecutive interpreting gives more room but carries the same burden of accuracy. In either mode the interpreter’s output is acted on immediately: a figure is accepted, a concession is made, a witness answer is recorded. There is no draft stage in which an error can be caught before it does damage.

The commercial consequence of an error therefore lands quickly and can be large relative to the assignment fee: a negotiation conducted on a misunderstood basis, a board decision taken on wrong information, a hearing that has to be re-run. That is what professional indemnity is for.

Confidentiality: the second, quieter risk

Interpreters are almost always bound to secrecy from more than one direction at once, and the obligations do not all work the same way.

Contractual. Non-disclosure agreements with the client or the agency, often signed at short notice before an assignment, sometimes with broad definitions of confidential information and uncapped indemnities. These are the obligations most likely to produce a claim, because they are written down and easy to enforce.

Professional. Codes of conduct published by professional associations for interpreters impose strict secrecy about everything learned in the course of an assignment. Breach is a disciplinary matter as well as a contractual one.

Statutory and general law. Where the material includes personal data, UK data protection law applies to how it is held, transmitted and disposed of. Separately, the equitable duty of confidence can attach to information imparted in circumstances importing an obligation of confidence, regardless of whether anything was signed.

A breach can happen without any negligence in the interpreting at all: notes left in a venue, a booth microphone left live, a working glossary shared with a colleague, an assignment discussed in general terms in a way that identifies the client, a laptop lost in transit, an email sent to the wrong recipient.

Does PI cover breach of confidentiality?

Sometimes, and it needs checking rather than assuming. Many professional indemnity wordings written for linguists extend to breach of confidentiality arising from the professional service, and to unintentional infringement of intellectual property. Others confine cover to negligent acts, errors and omissions in the service itself, which will not obviously reach a disclosure that was careless in handling rather than wrong in substance.

Three specific questions are worth putting to your broker before you buy:

Does the wording expressly refer to breach of confidentiality or breach of confidence? Does it cover liability assumed under a client NDA, or only liability that would exist at law in any event? And are defence costs included, and payable in addition to the limit or within it?

Where cyber cover fits

Professional indemnity responds to a claim brought by someone alleging loss. Cyber cover responds to an incident: it funds the response when a device is lost, an account is compromised or a system is encrypted, including forensic investigation, notification, legal advice and recovery. For an interpreter whose exposure is largely about custody of other people’s material, the two are complementary rather than alternatives. A ransomware incident on a machine holding client glossaries and preparation packs is a cyber event first and may only become a PI claim later.

Contract terms worth negotiating

Uncapped indemnities are the single most common problem in interpreting engagements. Where a client or agency contract requires you to indemnify them for all losses arising from any breach of confidence, without limit, you have accepted an exposure no insurance policy is designed to match. A cap by reference to a stated sum, or to the limit of indemnity you actually carry, is a reasonable position to put.

The second is scope creep in the definition of confidential information — definitions broad enough to catch information already public, or information you knew before the assignment, are worth carving back.

The third is subcontracting. If you use a boothmate, a relay interpreter or a transcriber, confirm you are permitted to, and that they are bound to the same standard. A breach by someone you brought in is your problem contractually.

Practical points

Keep preparation material on encrypted devices and delete it when the assignment closes. The safest confidential document is the one you no longer hold.

Treat handwritten notes as confidential material: destroy them after the assignment rather than leaving them in the booth or the bag.

Read the NDA before the day. An NDA presented at the venue is very difficult to negotiate; the same NDA seen two days earlier usually is not.

Notify your insurer of a suspected breach as a circumstance, promptly, even if no complaint has been made. Claims-made cover rewards early notification and punishes hindsight.

Frequently asked questions

Does professional indemnity insurance cover a confidentiality breach by an interpreter?

It can, but only if the wording says so. Some professional indemnity policies written for linguists expressly extend to breach of confidentiality and unintentional intellectual property infringement; others cover only negligent errors and omissions in the service itself. Confirm the position in writing before relying on it.

Am I covered for liability I take on under a client NDA?

Not automatically. Professional indemnity policies generally respond to liability that would arise at law in any event, and often exclude liability assumed purely by contract. An uncapped contractual indemnity in an NDA is therefore a contractual problem to negotiate, not something to insure around.

What limit of indemnity do conference interpreters need?

There is no professional minimum, so the limit is usually driven by what clients, agencies and framework contracts require, and by the size of the matters you work on. Whether the limit is each and every claim or in the aggregate, and whether defence costs erode it, matter as much as the headline figure.

Do I need cyber insurance as well as PI?

They do different jobs. PI answers a claim from someone alleging loss; cyber funds your response to an incident involving your own systems and the data you hold. If you routinely hold client preparation packs, recordings or personal data, the two are complementary.
