The label 'without prejudice' is not a universal shield for correspondence. Its protection concerns genuine settlement negotiations about a dispute and has exceptions, as the Supreme Court's Oceanbulk judgment illustrates. [1]
Decide what the communication is doing A formal notice, factual response or demand for performance may need to remain usable as open correspondence. Mixing those functions with settlement concessions can create avoidable uncertainty about later use.
Ask an adviser which communication should contain the proposal and which should record the operative facts. The content and context matter; adding a heading does not automatically protect a message that falls outside the rule.
Avoid making assumptions about later use Different labels, including 'without prejudice save as to costs', can have different purposes. Formal offers under procedural rules require their own analysis. Do not copy a heading from another dispute and assume the same consequences follow.
For mediation, check the contractual confidentiality arrangements as well. When terms are agreed, ensure the settlement record makes the intended obligations clear rather than leaving the parties dependent on ambiguous negotiating exchanges.
Identify the function of the message before drafting Ask what the communication needs to achieve. It may record a missed delivery, give a contractual notice, answer an allegation or propose a compromise. Those purposes should not be combined casually in one email. Explain to the adviser which facts you may need to rely on later and which proposals are being made to explore settlement. A deliberate structure can make the correspondence easier to understand and reduce uncertainty about whether a statement was an operative notification, a factual admission or a negotiating position.
Keep the underlying evidence available independently of the proposal. If a payment schedule relies on a calculation, retain the records supporting that calculation rather than assuming the proposal itself is the only explanation. Where a factual correction is needed, ask how it should be communicated without muddling the settlement discussion. This is particularly useful when the same people are continuing ordinary commercial work while advisers negotiate a dispute. Routine operational exchanges should not become an accidental vehicle for concessions intended for a different audience and purpose.
Understand why labels cannot answer every question The without-prejudice rule concerns the substance and setting of settlement negotiations, with recognised exceptions. Oceanbulk considered an interpretation exception concerning facts communicated in negotiations relevant to understanding the resulting agreement. That decision does not mean that every negotiating exchange can be shown to a court whenever a party wishes. Ask for advice on the particular material and proposed use before relying on either protection or an exception. A heading is a useful signal of intention, but it does not replace that analysis. [1]
Distinguish the purpose of different settlement labels and procedures. A message marked for possible later consideration on costs raises questions different from an ordinary open letter or a formal procedural offer. If using an established offer mechanism, check its requirements and consequences for the case. Avoid adapting wording from another dispute without understanding why it was used there. The practical issue is not which heading looks strongest, but whether the communication and process support the legal effect intended in the present circumstances.
Control internal circulation and forwarded exchanges Keep legal advice about negotiating strategy separate from the message intended for the opposing party. Before sending, review attachments, earlier messages in the chain and the recipient list. A carefully drafted proposal can still reveal restricted internal commentary if it is forwarded with the wrong history attached. Use a clean approved version where appropriate and retain a record of what was actually sent. This simple discipline is especially valuable when commercial staff and legal representatives share responsibility for correspondence.
Tell colleagues how to route replies. If a recipient responds with a mixture of factual allegations, demands and proposals, seek advice before copying selected passages into an open response or a court document. Avoid assuming that one party can unilaterally decide the later use of the whole exchange. Preserve the complete communication in its original form, including attachments and dates. An accurate record allows an adviser to examine context that may be lost in a screenshot or an isolated sentence repeated during an internal discussion.
Move from negotiation to an intelligible agreement When proposals converge, identify what remains unresolved and how the parties intend to record a binding bargain. Do not rely on an accumulated email chain if important terms are ambiguous or different participants understand approval conditions differently. Ask the drafting adviser to address the scope of the settlement, performance obligations and the relationship with any continuing proceedings. The negotiation record may explain the history, but clear operative wording reduces the need to debate later which exchange supplied an essential term.
If a dispute arises about the settlement itself, retain the full file and explain the precise issue to the adviser. Identify whether the question concerns existence, interpretation, performance or another matter, rather than assuming one answer applies to every use of negotiating material. Do not publish correspondence to demonstrate that the other party has behaved inconsistently without assessing the legal position. A considered review of the proposed use is more reliable than treating the words without prejudice as either an absolute prohibition or an empty formality.
Frequently asked questions
Should a contractual notice and a settlement concession always be placed in the same letter?
Consider their different purposes with an adviser, especially where the notice may need to remain usable independently of the negotiating proposal.
Does Oceanbulk make all settlement correspondence available for use in later proceedings?
No. It addresses a particular interpretation issue within the law's exceptions, so the proposed use of specific material still needs assessment.
Why check earlier email history before sending a settlement proposal?
A forwarded chain may contain internal advice or negotiating limits that were never intended for the other party or the wider recipient list.
Can I quote a favourable sentence from a negotiating exchange without considering the surrounding messages?
Preserve and assess the complete context first, because the nature of the exchange and intended use may affect its legal treatment.
What should an adviser be told when correspondence may be needed in a settlement dispute?
Explain the precise issue, the material concerned and how you propose to use it, rather than asking only whether the heading protects it.
