Marking Correspondence Without Prejudice: Protecting Your Legal Interests

Written by Cassine Bering | June 20, 2023

In the realm of legal matters, effective communication is vital. Parties involved in a legal dispute often engage in discussions and negotiations through correspondence such as letters, emails, and memos. However, there may be situations where parties want to ensure that their written communications do not have any prejudicial impact in future legal proceedings. In such cases, the practice of marking correspondence as “without prejudice” can provide a layer of protection. This blog will explore the concept of marking correspondence without prejudice and how it can safeguard your legal interests.

Understanding “Without Prejudice”

The term “without prejudice” has its roots in the common law system and is widely recognised as a legal principle in many jurisdictions. Marking correspondence as “without prejudice” means that the content of the communication, whether written or oral, cannot be used as evidence against the party who sent it in subsequent legal proceedings. This is not an absolute rule and there are exceptions but we have explored the general principle below.


The primary purpose of marking correspondence without prejudice is to encourage open and honest discussions between parties, especially during negotiations, settlement discussions, or attempts at resolving disputes. By labelling communications in this manner, parties can freely express their views, make offers, or disclose potentially damaging information, knowing that such statements cannot be used against them later in court.

The benefits of marking correspondence without prejudice include:

Encourages settlement: Parties can engage in frank discussions without fear that their words will be used against them. This fosters an environment conducive to finding mutually agreeable solutions and resolving disputes efficiently.

Protects admissions: Parties may make statements or admissions during negotiations that could be detrimental to their legal position. Marking correspondence without prejudice helps prevent these statements from being used as evidence against them in court.

Preserves confidentiality: By labelling communications as without prejudice, parties can maintain the confidentiality of their discussions. This is especially important if sensitive information or trade secrets are shared during the negotiation process.

Facilitates effective negotiation: The without prejudice label allows parties to explore creative solutions and consider settlement options more openly. It encourages a productive dialogue by minimising concerns about future legal implications.

Dos and Don’ts

To effectively use the without prejudice principle, there are a few important considerations:

Clear and explicit labelling: It is essential to clearly mark all written communications, such as letters or emails, with the phrase “without prejudice” or similar wording. This helps ensure that both parties understand the intention behind the communication and the associated legal implications.

Genuine settlement attempts: Without prejudice protection is typically afforded to communications made in a genuine attempt to settle a dispute. It is crucial to ensure that the discussions focus on settlement negotiations rather than other matters that might not be covered by the without prejudice rule.

Exceptions and limitations: While the without prejudice principle provides significant protection, there are exceptions and limitations to its application. Courts may disregard the without prejudice label under certain circumstances, such as instances of fraud, misrepresentation, or illegal conduct.

Marking correspondence without prejudice is a valuable tool in protecting your legal interests during negotiations and settlement discussions. By using this practice, parties can engage in open and honest communication without fear of later repercussions. It encourages effective negotiation, helps maintain confidentiality, and enables parties to explore potential solutions more freely. However, it is important to understand the limitations and seek legal advice when needed to ensure proper implementation of the without prejudice principle.
