How to Sue for Defamation in Ireland, Step by Step

How to sue for defamation in Ireland changed on 1 March 2026, when the Defamation (Amendment) Act 2026 commenced. The elements of the tort are the same, but there is a new statutory step before a summons can issue, a new route to the author of an anonymous post, and a new test for companies. This guide takes the steps in the order a claimant actually meets them, from the first screenshot to the choice of court, and it starts with the one fact that governs everything else: the date the statement was first published.

Step 1: Fix the Date and Start the Clock

Section 38 of the Defamation Act 2009 as amended gives one year from the date of first publication. The court can extend that to a maximum of two years, but only where the interests of justice require it, and the courts apply the rule strictly. Section 11 gives one cause of action for all publications of the same statement, so a post that is still online, still being read and still being shared by the same publisher does not restart anything: time runs from the day it first went up. Write down two dates before you do anything else: the date the statement was first published, and the date you first became aware of it. The Defamation Time Limit Calculator works both through, and the rule is explained in the one-year defamation time limit.

Step 2: Preserve the Evidence Before You Ask for Removal

Every element of the tort is a question of evidence, and the evidence disappears the moment the author gets nervous. Capture it first. Screenshots with the URL, date and time visible. The account name or handle of the author. The comments, shares, reactions and forwarded messages that prove publication to someone other than you, and the names of anyone who saw or heard it. For a shop accusation, keep the receipt, request the CCTV in writing and ask for the incident report. For a workplace matter, keep the reference, the email or the message. Keep any letter you have received. Do not reply publicly, do not engage with the author, and do not ask for the post to be taken down until the capture is complete, because a deleted post with no screenshot is a claim with no words in it.

Step 3: Check the Elements, and the Serious Harm Test If You Are a Company

Section 6 defines one tort: a statement that tends to injure a person’s reputation in the eyes of reasonable members of society, published to at least one person other than the plaintiff, that identifies the plaintiff. Publication to one other person is enough, which is why a WhatsApp group of five counts. Identification can be by name, by picture or handle, or by a description that people who know you would recognise. For an individual the claim is actionable without proof of financial loss. A company is different since 1 March 2026: under section 12 a statement about a body corporate is not defamatory unless it has caused or is likely to cause serious harm to its reputation, and for a company trading for profit that means serious financial loss. A sole trader is an individual and faces no such test. At this stage you also look at the defences the other side will raise — truth under section 16, honest opinion under section 20, qualified privilege under section 18 including the new section 18(1A) privilege for a retailer’s good-faith inquiry, and fair and reasonable publication under section 26 for the media — because the letter in Step 5 has to anticipate them. The Defamation Claim Checker runs the elements from your answers.

Step 4: Report to the Platform and, If the Author Is Anonymous, Identify Them

For anything online, report it to the platform first. The Digital Services Act, in force since 17 February 2024, requires platforms to run notice-and-action systems, and Coimisiún na Meán, as Ireland’s Digital Services Coordinator, enforces the Online Safety Code for video-sharing platforms. A platform report is not a substitute for the steps that follow, but it is quick and it sometimes removes the post. If the author is anonymous, section 45 lets the Circuit Court order an intermediary — the platform, host or provider — to disclose information identifying them where the interests of justice require it; the court may order you to pay the intermediary’s costs. Before March 2026 that needed a High Court Norwich Pharmacal application. The major platforms run their European operations from Dublin, so the order is made against a Dublin-registered company. The identification stage runs inside the same one-year period, which is the main reason anonymous cases cannot wait.

Step 5: The Solicitor’s Letter

The letter sets out the exact words, the date and place of publication, the people it reached and why it identifies you, and it seeks removal, a correction with the same prominence as the original, an apology, an undertaking not to repeat the statement and the preservation of the author’s records. A good letter anticipates the defence: if the author will say the words were opinion, the letter shows why they were a statement of fact; if the author will plead truth, the letter sets out why it cannot be proved. The Act makes it easier for a defendant to back down than it used to be. An apology under section 24 is not an admission of liability, and an offer of amends under sections 22 and 23, with a correction and apology of the same or similar prominence as the original, is a recognised way out that affects costs if it is refused. Many matters end here. The letter is quoted as a fixed sum after the consultation, as set out on our fees page.

Step 6: The ADR Declaration Under Section 34K

Part 4B of the Act, in force since 1 March 2026, adds a step that did not exist before. Before issuing, your solicitor must inform you of the specified alternative dispute resolution options — a Press Council complaint, or the right of reply under the Broadcasting Act — and must file a statutory declaration confirming that with the originating document (section 34K). The limitation period is suspended while a specified ADR procedure runs. Sections 34M and 34N, which would let the court invite the parties to ADR and attach costs consequences, are not commenced. For a newspaper or broadcast the step is both a requirement and a tactic, because a Press Council finding or a right of reply can deliver a correction faster than any court. For a social media post it is a declaration that still has to be sworn before the summons issues. Separately from the statutory options, most Circuit Court defamation claims settle before hearing, and a solicitor trained as a mediator approaches that stage with the settlement in view from the start.

Step 7: Choose the Court

The Circuit Court’s jurisdiction in defamation is €75,000. It can grant a declaratory order under section 28 that the statement was false and defamatory, a correction order under section 30 and a prohibition order under section 33 against further publication, it is faster and cheaper, and it is where the volume now sits: in 2024 it heard 228 defamation cases to the High Court’s 61. The High Court has unlimited jurisdiction and, for actions commenced on or after 1 March 2026, sits without a jury; earlier cases keep theirs. The choice is made on the gravity of the words, the reach of the publication, the evidence of harm and the costs risk. Court proceedings carry a risk of being ordered to pay the other side’s costs if the claim fails, and that risk is explained in writing before anything is issued. The fees side is set out in what it costs to sue for defamation.

Step 8: Issue, Plead and, Usually, Settle

Proceedings issue by civil bill in the Circuit Court or by summons in the High Court, with the section 34K declaration filed alongside. The defendant delivers a defence, which is where truth, honest opinion, privilege or an offer of amends is formally pleaded. A defendant may lodge a sum in court, which changes the costs position if the eventual award does not exceed it. Most Circuit Court claims settle before hearing, often once the defence has been exchanged and both sides can see the evidence. There is no fixed timetable for a defamation action, but there are fixed dates: issue within the year, note any ADR suspension, and treat the two-year outer limit as a discretion the court rarely exercises rather than a deadline. The practice page on defamation of character sets out the claim as a whole, and the first consultation establishes which of these eight steps your matter actually needs. Many need only the first five.
