Cease and Desist Letter (Ireland)

A Cease and Desist Letter in Ireland puts a demand or grievance in writing, sets out what is owed or wrong, and states the action required to resolve it, and is governed by the Defamation Act 2009.

Cease and desist letters in Ireland are grounded in the general law of tort, contract, and intellectual property. Key tort law principles include: the tort of passing off (actionable without a registered trade mark); defamation under the Defamation Act 2009; private and public nuisance; trespass to person, land, and goods; and harassment under the Non-Fatal Offences Against the Person Act 1997.

Intellectual property rights in Ireland are protected by a suite of statutes. The Trade Marks Act 1996 (as amended, most recently to implement EU Directive 2015/2436 harmonising trade mark law) gives the registered proprietor of a mark the exclusive right to use it and to restrain infringing use. Trade marks may be registered nationally with the Intellectual Property Office of Ireland (IPOI) or at EU level through the European Union Intellectual Property Office (EUIPO), in which case the EU Trade Mark (EUTM) has unitary effect across all EU member states including Ireland. The Copyright and Related Rights Act 2000 — as supplemented by the European Union (Copyright and Related Rights in the Digital Single Market) Regulations 2021 (S.I. No. 567 of 2021) implementing EU Directive 2019/790 — protects original literary, artistic, musical, and dramatic works. The Patents Act 1992 protects registered patents, and the Industrial Designs Act 2001 protects registered designs. The IPOI publishes guidance on enforcement options at ipoi.gov.ie.

Data protection law — the GDPR (Regulation (EU) 2016/679) and the Data Protection Acts 1988-2018, supervised by the Data Protection Commission (DPC) — provides additional grounds for a cease and desist demand where a party is unlawfully processing personal data. A cease and desist letter is a common first step before making a formal complaint to the DPC.

A cease and desist letter should be prepared by a solicitor experienced in the relevant area of law. It must not make admissions, exaggerate legal claims, threaten criminal proceedings inappropriately, or itself constitute a defamatory publication. Where ongoing IP infringement or publication of defamatory content is causing irreparable harm, the solicitor should advise on the availability of an emergency ex parte interlocutory injunction from the High Court, obtainable within 24 to 48 hours in the most urgent cases.

A Cease and Desist Letter is needed whenever a party wishes to formally notify another person or entity that their conduct is unlawful or in breach of legal rights, and to demand that they stop before court proceedings are commenced.

Trade mark or brand infringement: Where a business is using a name, logo, or mark identical or confusingly similar to the sender's registered mark, a cease and desist letter is the standard first step. The letter should identify the IPOI or EUIPO registration number, describe the infringing use, and demand immediate cessation and delivery up of infringing materials. The IPOI's Enforcing Your IP guidance confirms a cease and desist letter is the typical initial enforcement step before litigation under the Trade Marks Act 1996.

Copyright infringement: Where a party has copied, adapted, or published copyright-protected works without authorisation, the letter should identify the specific works, describe the infringing acts, and demand removal from websites and other media. The European Union (Copyright and Related Rights in the Digital Single Market) Regulations 2021 expanded rights holders' tools, particularly for online platforms.

Breaches of confidentiality and non-compete obligations: Where a former employee or contractor is using confidential information or competing in breach of a non-compete clause, the letter should identify the specific obligations and consequences of continued breach.

Online defamation: Where defamatory content has been published online, a cease and desist letter to the publisher and, where applicable, to the platform host demanding removal is often the most efficient first step. The Defamation (Amendment) Act 2024 reformed key aspects of the Defamation Act 2009 and introduced updated rules on online publications, strengthening the case for swift action.

Harassment and stalking: A cease and desist letter from a solicitor formally warns the perpetrator of the legal consequences of their conduct under the Non-Fatal Offences Against the Person Act 1997, and demonstrates that the victim has sought legal advice — which is relevant to any subsequent application for a safety order or protection order.

Unfair business practices: Where a competitor is engaging in misleading advertising, passing off, or other practices contrary to the Consumer Protection Act 2007, a cease and desist letter may precede a complaint to the Competition and Consumer Protection Commission (CCPC).

A well-drafted Irish Cease and Desist Letter should include the following key elements.

Sender identification: The letter should clearly identify the sender or their solicitor on headed notepaper, with solicitor's reference and contact details.

Recipient identification: The letter must be addressed to the correct legal entity — including the company's registered name, CRO number, and registered office for corporate recipients.

Date and mode of delivery: The letter should be dated and sent by a method that provides evidence of delivery (registered post, courier, or email with read receipt). Urgent letters may be sent by email and followed by hard copy.

Description of the offending conduct: The description of the alleged infringing or unlawful acts should be as precise and factual as possible, referencing specific dates, URLs, screenshots, and other evidence. Vague descriptions weaken the sender's credibility and legal position.

Legal basis for the demand: The letter should cite the specific statutory provision or contractual clause on which the demand is based — for example, infringement of a registered trade mark under the Trade Marks Act 1996 (with the IPOI or EUIPO registration number); breach of copyright under the Copyright and Related Rights Act 2000; the tort of passing off; defamation under the Defamation Act 2009 (as amended by the Defamation (Amendment) Act 2024); or unlawful processing of personal data in breach of the GDPR.

Specific demands: The letter must set out clearly what the recipient must do — for example, immediately cease all infringing activity; remove all infringing content from specified websites; provide a written undertaking not to repeat the conduct; deliver up or destroy infringing materials; account for all profits made from the infringing activity; and pay the sender's solicitor's costs.

Deadline for compliance: A clear deadline — typically seven to 14 days, reduced to 24 to 48 hours for urgent matters.

Consequences of non-compliance: The letter should warn of the potential for an interlocutory injunction, damages (including additional damages for flagrant infringement under section 128 of the Copyright and Related Rights Act 2000), and an account of profits, with the recipient liable for the costs of proceedings. Threats of criminal prosecution should only be made where genuinely applicable.

Without Prejudice reservation: Any letter containing a settlement offer should be marked 'Without Prejudice' to protect its contents from being used in subsequent proceedings.

Mediation reference: Under the Mediation Act 2017, parties are encouraged to consider mediation before issuing proceedings. A court may take an unreasonable refusal to engage in mediation into account when making a costs order under Order 99 of the Rules of the Superior Courts and section 169 of the Legal Services Regulation Act 2015.
