Plain-language answer
"Without prejudice" is a label used on communications that are genuine attempts to settle a dispute. Its general purpose is protective: statements and offers made in real settlement negotiations generally cannot later be used against the person who made them if the dispute goes to a hearing. The idea is to let people negotiate openly — including offering compromises — without those offers becoming ammunition.
Two common misunderstandings are worth clearing up. First, the words are not magic: writing "without prejudice" on a letter does not protect it unless the communication genuinely relates to settling a dispute. A demand, a threat, or an ordinary notice does not become protected because of a label. Second, the absence of the words does not necessarily remove protection — what generally matters is the substance: was this a genuine settlement communication?
For tenants, the practical takeaways are simple: if a landlord's letter says "without prejudice," it usually signals settlement talk; if you make a settlement offer yourself, labelling it accurately is sensible; and if it matters whether a specific document can be used at a hearing, that is a question for a legal professional, because the rules have nuances.
Why it matters
Settlement discussions are common in landlord-tenant disputes — over arrears, move-out dates, or repairs. Understanding the label helps you read letters correctly and negotiate without fear that every compromise will be quoted back at a hearing.
It also helps you avoid over-reading it: tenants sometimes assume a "without prejudice" letter has some special legal force over them. It does not — it is about how the communication can be used as evidence.
Facts that affect the answer
Based on the information available, these are the kinds of facts that commonly change how a situation like this is assessed:
- Whether the communication was genuinely aimed at settling an existing dispute.
- Whether both sides treated the exchange as settlement negotiation.
- Whether the document does something other than negotiate — formal notices generally are not settlement communications.
- Whether a settlement was actually reached, which can change how related communications are treated.
- The forum involved — how evidence rules apply can vary, and a legal professional can advise for your specific proceeding.
Evidence to preserve
Preserve these now, in their original form
- The complete communication — never just an excerpt — with its date and delivery method.
- The chain of correspondence around it, showing context.
- Any final settlement agreement, which is generally a different kind of document from the negotiations that produced it.
- Your own notes about verbal settlement discussions, dated at the time.
- Copies of anything you signed.
Common mistakes
- Assuming the label makes any letter untouchable — substance, not labels, generally controls.
- Ignoring a "without prejudice" letter entirely because it looks technical, when it may contain a real offer worth considering with advice.
- Making damaging admissions in ordinary (non-settlement) correspondence, thinking the label rules protect everything.
- Signing a settlement without understanding it is generally binding, whatever the negotiations were labelled.
- Guessing about whether a document can be used at a hearing instead of asking a legal professional.
Possible official process
There is no filing process attached to the phrase itself — it is a concept in the law of evidence. Where it matters is at hearings, when one side tries to rely on settlement communications.
If settlement is reached in an LTB matter, it may be recorded formally — for example in a mediated agreement or consent order — which changes its status from negotiation to binding outcome.
If you are unsure whether to respond to a settlement letter, community legal clinics can review it with you, often quickly.
