Cease and Desist Letter — Formal Warning (England & Wales)

A Cease and Desist Letter — Formal Warning in the United Kingdom puts a demand or grievance in writing, sets out what is owed or wrong, and states the action required to resolve it, with its requirements set by the Defamation Act 2013.

Unlike some other jurisdictions where cease and desist letters have no formal legal framework, the English legal system integrates the pre-action letter into the formal structure of civil litigation through Practice Direction — Pre-Action Conduct and Protocols under the Civil Procedure Rules. This Practice Direction requires parties to exchange sufficient information about a dispute before issuing proceedings, to attempt to resolve the dispute without litigation, and to consider alternative dispute resolution. A well-drafted Letter Before Action is the standard mechanism for meeting these obligations and for demonstrating to the court, if proceedings are eventually issued, that the claimant acted reasonably in the pre-litigation phase.

Cease and desist letters in England and Wales are most commonly used in intellectual property disputes, where they are sometimes called “cease and desist letters” in the US-influenced context of online trade mark and copyright enforcement, but which function as Letters Before Action within the English legal framework. The Pre-Action Protocol for Intellectual Property Claims provides specific guidance for IP disputes, requiring the claimant’s letter to identify the IP rights relied upon, describe the alleged infringement, specify the remedies sought, and give the defendant a reasonable period to respond.

Beyond intellectual property, cease and desist letters are used in defamation cases under the Defamation Act 2013, harassment cases under the Protection from Harassment Act 1997, breach of confidence cases (including trade secret disputes under the Trade Secrets (Enforcement, etc.) Regulations 2018), passing off cases under common law, and general contract breach cases. In each context, the letter puts the recipient on formal notice, creates a record that the sender attempted to resolve the matter before resorting to litigation, and establishes the date from which the recipient is deemed to have known of the wrongful conduct (which is relevant to the assessment of damages and the equitable remedy of laches).

A cease and desist letter should be distinguished from a statutory notice (such as a section 21 notice in housing law, or a section 25 notice in commercial tenancy law), which has prescribed forms and strict procedural requirements. A cease and desist letter has no prescribed form but must be carefully drafted to achieve its intended legal effect, to comply with the applicable Pre-Action Protocol, and to avoid the risk of groundless threats liability in intellectual property cases under the applicable intellectual property statutes.

A Cease and Desist Letter is needed in England and Wales whenever a person or business discovers that another party is engaging in conduct that infringes their legal rights and they wish to demand that the conduct stop before commencing court proceedings. The need for such a letter arises in a wide range of circumstances.

Intellectual property infringement is the most common trigger for cease and desist letters in England and Wales. Copyright infringement under the Copyright, Designs and Patents Act 1988 arises when a person copies, distributes, communicates to the public, or adapts a substantial part of a protected work without the copyright owner’s authorisation. Common situations include the unauthorised use of photographs, music, video content, written articles, software code, logos, and design works. A cease and desist letter demands immediate removal of the infringing content, confirmation that it has been destroyed, and compensation for the infringement.

Trade mark infringement under the Trade Marks Act 1994 arises when a person uses a sign identical or similar to a registered trade mark in relation to identical or similar goods or services, or takes unfair advantage of the distinctive character or repute of a mark with a reputation. Online infringement through the use of similar brand names, logos, or domain names is increasingly common. A cease and desist letter in a trade mark case demands that the infringer cease using the mark, rebrand, deliver up or destroy infringing goods, and provide undertakings.

Passing off at common law protects unregistered trade marks and business goodwill. Where a business has built up goodwill and reputation in a name or get-up, and another party misrepresents their goods or services as being connected with the first business, causing damage, a cease and desist letter is the appropriate first step.

Defamation under the Defamation Act 2013 arises when a statement of fact is published that causes serious harm to the claimant’s reputation, subject to the serious harm threshold in section 1. With the proliferation of online reviews, social media posts, and blog articles, defamation cease and desist letters are increasingly common. The letter demands removal of the defamatory statement, publication of a correction or apology, and undertakings.

Harassment under the Protection from Harassment Act 1997 involves a course of conduct (two or more related acts) that causes another person alarm or distress, where the harasser knows or ought to know that the conduct amounts to harassment. A cease and desist letter warns the harasser that their conduct is unlawful and that the victim will seek an injunction and damages if it continues.

Breach of confidence arises when a person discloses or uses confidential information (trade secrets, customer lists, business plans, technical know-how, personal information) in breach of a duty of confidence. A cease and desist letter demands that the confidential information be returned or destroyed and that further misuse cease.

A legally effective Cease and Desist Letter (Letter Before Action) for England and Wales must contain several key elements to confirm that it complies with the Civil Procedure Rules’ Pre-Action Protocols, puts the recipient on adequate notice, and maximises the sender’s options if proceedings are ultimately required.

Party identification must be precise. The sender’s full legal name and address must be stated clearly, together with their email address and, if appropriate, a reference to the solicitor or agent acting on their behalf. The recipient must also be identified by full legal name and address. If the recipient is a limited company, the Companies House registered name and number should be used. Identifying the wrong legal entity may render the letter ineffective as a pre-action demand and may complicate subsequent proceedings.

The subject matter and legal basis must be set out with specificity. The letter must identify: (1) the rights the sender relies upon (for example, a registered trade mark with its registration number, the specific copyright works, or the relevant contractual provisions); (2) the conduct complained of (with dates, locations, URLs, product descriptions, and evidence references); and (3) the applicable legal framework (which acts, sections, or common law principles have been breached). Vague allegations undermine the letter’s credibility and may not satisfy the Pre-Action Protocol obligations.

Evidence should be summarised without being fully disclosed. The sender should indicate the nature of the evidence supporting the claim (for example, screenshots, purchase records, expert opinions) without necessarily exhibiting all of it at this stage. This demonstrates that the claim is well-founded while preserving flexibility for the formal proceedings.

The demands must be explicit and numbered. Each demand should be stated separately: (1) cessation of the conduct; (2) destruction or removal of infringing materials; (3) provision of written undertakings; (4) payment of compensation. The demands should be reasonable and proportionate; excessive demands may undermine the letter’s credibility and may affect the court’s assessment of costs.

Groundless threats provisions must be considered for intellectual property claims. Under sections 21 to 26 of the Trade Marks Act 1994, sections 253 to 255 of the CDPA 1988, and section 70 of the Patents Act 1977, a person who makes a groundless threat of infringement proceedings may themselves be sued for damages and an injunction. Care must be taken to confirm that the allegations in the letter are well-founded before sending it.

A reasonable response deadline must be given. Under Practice Direction — Pre-Action Conduct, a reasonable period is typically 14 days for straightforward matters and 28 days for more complex ones. The letter should state both the number of days and the calendar deadline date.

A warning of court action must clearly state: the court in which proceedings will be issued; the remedies to be claimed (injunction, damages, delivery up, costs); and, if applicable, the intention to apply for an interim injunction without further notice.

ADR must be offered. Parties are expected to consider mediation and other forms of ADR before litigation. The letter should offer mediation and warn that unreasonable refusal to consider ADR may result in adverse costs consequences under CPR Part 44.

A without-prejudice-save-as-to-costs marking protects the letter from use as evidence on the merits while preserving the court’s ability to consider it when determining costs.

A reservation of rights clause confirms that nothing in the letter waives any of the sender’s legal rights or remedies.
