Letter before legal action in defamation
Getting posts removed, fast, with a letter that actually does the work
If you have come to this page, the chances are that something has been published online about you or your business that should not have been published, and you want it dealt with. You want the posts taken down, you want the person responsible to stop, and you want the matter behind you. Most clients who come to us with this kind of problem want practical, pragmatic legal help that produces a real-world result quickly and at sensible cost. A properly drafted letter before legal action is, in most defamation cases we run, the single piece of work that makes that result possible.
If the content is on a platform and you want the host put on notice, our defamation removal letter guide covers that route. If you can name the person responsible and you want to write to them directly, our cease and desist letter guide covers the drafting and the service of that letter. This page covers what to do when you are heading towards formal proceedings: how the pre-action protocol fits into that, what to do if limitation is running out, and what we have learned about getting the best result out of the letter after many years of writing them.

What is the purpose of a letter before legal action in defamation cases
A letter before legal action serves two purposes, and they pull in the same direction.
The first purpose is procedural. The Civil Procedure Rules expect parties to communicate properly before a claim goes to court, and defamation has its own dedicated set of rules for that exchange in the form of the Pre-Action Protocol for Defamation. The protocol sets out what the claimant includes in the letter, the kind of response the defendant gives back, and the timeframe both sides work to. Following the protocol matters because, if the case does end up at court, the court looks at whether both sides behaved sensibly before proceedings started, and that look-back carries practical consequences for costs and case management later on.
The second purpose, and the one that matters more in practice, is leverage. The letter is the moment when the person who has been publishing about you hears, sometimes for the first time, from a specialist solicitor. They now have a real choice to make. They can engage and try to resolve the matter, or they can ignore the letter and find themselves on the receiving end of a claim form. A well-drafted letter sets the case out clearly enough that the recipient sees, in a few minutes of reading, that the case against them is real, that the cost of fighting it is high, and that the better outcome for everyone is to engage and reach a settlement.
The best letters do both jobs at once. They satisfy the protocol on the page, and they read like a serious piece of legal work that the recipient takes seriously off it. Those are the letters that produce the outcome the client actually wants, which is the posts taken down, the matter put to bed, and the client free to move on with their life and their business.
What are the consequences of failing to send a letter before legal action in defamation cases
The technical answer to this question is that the court has a discretion to penalise a party who has not followed the Pre-Action Protocol when it comes to deciding who pays the costs of the litigation. That answer is correct, and most law firm articles on the subject stop there. It is also the least useful answer for someone who has defamatory content sitting online about them and is trying to decide what to do about it.
The consequence that actually matters is what happens to your life while the case grinds through court rather than resolving on the letter. The posts stay where they are. The person who has been making the allegations carries on doing so, sometimes more confidently because no professional letter has yet appeared in their inbox. Other people see the publications, screenshot them, share them. The matter takes over a year of your working week rather than a handful of weeks. Costs run from the low thousands into the tens of thousands. Damages, where a court ends up awarding them, do not undo any of that. The whole point of the letter before action is to short-circuit all of it: to put the person responsible on serious notice early, give them a clear route out of the dispute, and produce the result you actually came to us for on a timeline you can live with.
There is a related practical consequence worth flagging. Where a claimant goes straight to issuing a claim, the defendant and their lawyers can use the absence of pre-action correspondence as a reason to slow the case down further, asking for more time to file a defence or applying for a stay so that the protocol can be followed retrospectively. The case has formally started but nothing useful is happening on the ground. The client has paid the issue fee, the matter is on the public record, and the posts are still up. That is exactly the position the letter before action was designed to avoid.
So the cost-sanction risk is real but it is, at most, a fraction of the picture. The consequence that should drive the decision is the loss of months of your life and tens of thousands in additional fees, while the posts stay online and the campaign carries on. That is what we work to avoid for every client who walks through our door, and the letter before action is the most reliable tool we have for avoiding it.
What information needs to be included in a letter before legal action in defamation cases
The Pre-Action Protocol for Defamation lists the headline items the letter should cover: who the claimant is, where and when the publication appeared, the precise words you complain about, the meaning you attach to those words, why you say the publication is defamatory, the relief you ask for, and any matters you want the court to take particularly seriously. That is the page-one summary, and it is what most law firms repeat back to you in their own articles on this subject. We want to take you a little further into the practical questions that sit underneath those headings, because the practical questions are where the case actually stands or falls.
Getting the defendant right
A lot of the thinking on a letter before action happens before you write a single sentence of it. You decide who you are writing to, and just as importantly who you are not. That sounds obvious on the page, but it is one of the places we sometimes see DIY letters come unstuck.
We sometimes see the wrong individual named on a letter. We see an individual named when really it is the company behind the post that has published it. We see a director named personally when only the company should be the defendant. Errors of that kind have real-world costs even before you reach court. Once you have sent a letter that sets out the defamatory content to the wrong person, you have now told that person what is being said about you. You have just republished the defamation yourself, this time to a third party who had no need to know. The privacy implications, the embarrassment, and the delay involved in walking the letter back and starting again all run against the very things you wrote the letter to fix.
There is a longer-term cost too. A claim brought against the wrong person can fall apart at court on what looks like a technicality, and the case is lost. The defendant then has every reason to go online and say so. They tell the world they were sued for defamation and they won, the publications stay where they are, and the campaign sometimes continues with renewed confidence. That is the outcome we work hardest to avoid, and it is why you need to settle the question of who is on the front of the letter before you send anything.
The right way to handle this is to invest the time in identification before the letter goes out. A letter that names the wrong recipient is not easy to walk back. A letter that goes to the right recipient on day one carries an authority that a corrected second letter rarely recovers, and it sets the tone for everything that follows.
When you do not know who the defendant is
Sometimes the problem runs in the other direction and you do not know who the defendant is at all. A social media account behind a pseudonym. A Google review left under a first name. A blog post on a domain registered through a privacy proxy. The good news is that not knowing the publisher's name does not have to stop you bringing a claim.
There are two main routes from here. The first is to identify the person behind the post and then write to them in the usual way. The second is to bring the proceedings against persons unknown, which can in the right case be considerably faster and simpler than the conventional pre-action exchange of letters.
The logic of the persons-unknown route is straightforward once you see it. If you cannot identify the publisher, you cannot send them a letter, and the protocol cannot run. The court allows you to issue the claim against persons unknown instead, and you apply for the relief you would otherwise have asked the defendant to provide. Because the defendant is, by definition, unknown, they cannot turn up to oppose. The order you want comes through unopposed. In most defamation matters that order is an injunction, and once you have the injunction in your hand you take it to the platforms and ask them to remove the posts. That is the result that matters: the posts gone and the matter closed.
We have run persons-unknown matters in different shapes across defamation, privacy and harassment work. Our GYH v Persons Unknown privacy injunction is an example of the same route used in a privacy context. Our social media harassment injunction case study shows the route used to take an account-based harassment campaign off the platforms when the person behind the account would not identify themselves.
Before the court entertains a claim against persons unknown, it expects to see that you tried to identify the publisher and that the effort did not produce a workable answer. Three routes do that work, and we use them in combination depending on the case. Our open-source intelligence (OSINT) team runs the identification work in-house, which on a good day produces the answer before we need any court route at all. Inside the UK, a Norwich Pharmacal Order against the platform or the hosting provider can compel the disclosure of subscriber data where in-house investigation does not get there: we run a dedicated disclosure orders service for these applications, including a low cost Norwich Pharmacal Order service for the more straightforward cases. Where the data sits in the United States, a section 1782 subpoena under US federal procedure does similar work. We advise on which of the three routes fits the particular case.
Telling the difference between fact and opinion
Another call you make before any words go on the page is whether the content you are complaining about is a statement of fact or an expression of opinion. A false statement of fact can be defamatory. An opinion, even a sharply expressed one, generally cannot, provided the person expressing it can point to some basis for it. That sounds like a clean line, and in practice it is one of the most contested questions in defamation law.
The distinction matters at the letter-before-action stage because the case you set out in the letter is the case you commit to. If you ask the recipient to retract a statement on the basis that it is a false statement of fact, and the recipient and their lawyers come back and say, fairly, that the words are clearly an opinion, your letter has not only failed; it has produced a written record of a position you may now have to defend if the case escalates. That position is not easy to revisit later. Section 3 of the Defamation Act 2013 provides a statutory defence of honest opinion to a publisher who can show that the statement was an expression of opinion, that the publisher indicated the basis of the opinion, and that an honest person could have held it on the facts known at the time. A letter that misreads opinion as fact effectively hands the defendant the framework for that defence on a plate.
The complication is that the words themselves do not always settle whether a particular sentence is fact or opinion. The answer depends on the context the publication appeared in, the tone of the surrounding posts, the platform on which they appeared, and the way an ordinary reasonable reader would have understood them. Courts sometimes hold preliminary issue hearings to decide this kind of question. The case of David Paisley v Graham Linehan is an example of the kind of preliminary hearing where a court does precisely that work on the meaning of online publications. It is a useful read for anyone who assumes the distinction between fact and opinion is always obvious.
This is one of the practical reasons we are wary of letters generated by ChatGPT or assembled from internet templates. A template will list the words you complain about and label them defamatory; it cannot make the call between fact and opinion in the way the case actually requires, and a wrong call here can cost you the case.
What to ask for, and where to land on damages
In your letter before action, you ask for relief. Most defamation letters cover four kinds, and you weight them by the facts of your case. Removal of the publications. An apology in terms you can agree. An undertaking not to repeat or republish the same or similar allegations in future. And damages to compensate for the harm already caused. A private individual harassed on social media is usually most interested in removal and an undertaking; a business with quantifiable losses is more interested in damages and a clear retraction. You calibrate the letter to your case rather than asking for everything by default.
On damages, our working position is that you do not put a specific figure in the recipient's hand. The better approach is to set out the harm done, leave the financial element for them to come back on, and invite them to make a proposal. There are two practical reasons for that. First, putting the burden on the recipient to make the opening offer means they have to commit to a number first, which shifts the negotiation in your favour. Second, an offer made by them, even one you find too low, narrows the dispute from "did they do it" to "how much for it", which is a much easier dispute to settle than the first one.
The commitment baked into the letter
A point that does not always get the attention it deserves is that the letter before legal action is, in real terms, the case. The position you set out in it is the position you commit to for the rest of the matter. Cases do develop and refinements are normal. The central elements stay where you put them: who you say did it, what you say they did, what meaning you say their words carry, what harm you say has been caused, and what you are asking for. All of that is now on the record. Walking any of it back later costs you, both in legal fees and in the credibility you have with the other side.
The letter before legal action is, in real terms, the case. The position you set out in it is the position you commit to for the rest of the matter. Walking any of it back later costs you, both in legal fees and in the credibility you have with the other side.
That is the practical reason a defamation specialist drafts the letter rather than a generalist or, worse, an automated tool. The solicitor makes the legal judgement calls at the moment the words go on the page, and those calls bind you for the rest of the case. Getting them right is the single largest contribution we make to the matter.
What if you are running close to the limitation period
Defamation has a short limitation period. Under section 4A of the Limitation Act 1980, you have to bring a claim for libel or slander within one year of the date on which the cause of action accrued, which is normally the date of first publication. The court has a discretion under section 32A of the same Act to extend the period in fairly narrow circumstances, but the working assumption is that the one-year clock applies and that it starts running on the day the words first went up.
If you come to us with weeks rather than months to spare on that clock, the question of how to handle the letter before action changes. The protocol envisages a period of correspondence followed by a sensible time for the recipient to consider their position, and that timetable does not fit comfortably inside a limitation window that is about to expire. What we usually do in those cases is file a protective claim, which means issuing the claim form within the limitation period so that proceedings are formally on foot, and then continuing the pre-action correspondence in parallel.
That works because the rules on serving the claim form give you a sensible window after issue. Once you have issued the claim form, you have a period within which to serve it on the defendant, and if that period is not long enough, the court can extend it. Filing the claim form does not commit you to immediate trial preparation. It stops the limitation clock and keeps your options open.
There is a strategic side-effect that sometimes turns out to matter. When the letter before action lands on the recipient's desk and explains that we have already filed a claim protectively, the recipient understands very quickly that the case is real and that the timetable is now in your hands rather than theirs. We have seen recipients move from refusing to engage to negotiating a settlement within days of that letter arriving. The protective claim is not just a defensive move on limitation; it is also a piece of leverage that meaningfully changes the tone of the response.
A worked example: Red Rock Resources v Carp
To bring all of this onto something concrete, here is a Cohen Davis matter in which the letter before legal action did most of the work, the case settled cleanly, and the client put the matter behind it within a few weeks rather than a few years.
Our client was Red Rock Resources PLC, a London-listed gold mining company. Over a period of months, one of its small but vocal investors, Mr Gary Carp, had been publishing a series of allegations on Twitter, on the Proactive Investors forum and by direct email. The allegations included fraud, mismanagement and other serious wrongdoing on the part of the Chairman, Mr Andrew Bell, and the rest of the board. Other investors started picking up the campaign, then a section of the financial press did, and the company started to see the kind of effect on confidence in the stock that a listed company cannot afford to ignore.
We ran the pre-action stage of that matter carefully. We drafted a letter before action that set out the words complained of, the meanings we attributed to them, the harm the campaign was doing to the company and to Mr Bell personally, and the relief the company would ask the court to award if the matter did not resolve. We sent the letter and then spent three weeks attempting to resolve the matter with Mr Carp in correspondence, on the terms the protocol envisages. That was the right thing to do; for a listed company it was also about the longest the board could afford to wait before acting publicly.
When the pre-action exchange did not produce a resolution within that window, the company filed a claim for libel in the High Court in London. The combination of the letter, the engagement that followed it, and the visible willingness to issue proceedings worked. Within a further three weeks Mr Carp agreed to settle. He issued a public apology retracting the allegations, accepted that the Chairman and the directors had done nothing wrong, and paid a significant undisclosed sum in damages. The company donated the damages to the Build Africa charity, working in Uganda and Kenya. The whole matter, from letter to settlement, ran to approximately six weeks. The full case is on our defamation by investors page.
The lesson the case carries for the reader of this article is not that defamation matters always resolve in six weeks; they do not. The lesson is that the letter before action is what made the six-week resolution possible. We set the position out clearly enough, anchored the legal grounds specifically enough, and stood visibly enough behind the letter that the recipient understood, fairly early on, that the case against him was real and that defending it was going to be considerably more painful than settling it. That is what a well-drafted letter does. The mechanics of the protocol sit in service of that result.
What happens after the letter has been sent
Once the letter has gone out, the recipient has a defined period to respond. The Pre-Action Protocol does not fix a precise number, but the working norm in practice is fourteen days, with longer where the publication is complicated or where the recipient needs time to take legal advice. Where the matter is straightforward and the recipient is plainly the person responsible, fourteen days is usually fair. Where the recipient is a company that needs to take advice from in-house counsel and external lawyers, a slightly longer window is reasonable.
If the recipient engages, what usually follows is a structured exchange of letters in which the issues narrow. They may offer to remove the posts but not to apologise. They may agree to a private apology but resist a public one. They may dispute the meaning of the words. They may accept the meaning but offer a smaller sum in damages than you have indicated. Each of those is a point of negotiation, and most defamation matters that settle, settle through that exchange.
If the recipient ignores the letter or refuses to engage, the next step is to issue the claim form, with the costs and timetable consequences that follow. Our cease and desist letter guide covers the mechanics of getting the letter to the recipient, by post, by email, by personal service through a process server, and what to do where the recipient is hard to reach. How the letter reaches the recipient affects how they read it, and that guide goes into the choice of route in detail.
Why is it preferable to instruct a specialist solicitor to draft the letter before legal action in defamation cases
A lot of what we have covered above involves judgement work. Whether a statement is fact or opinion. Whether the right defendant is the individual or the company. Whether the case is strong enough on serious harm to be worth pursuing. Whether persons-unknown proceedings are a faster route than identification. Whether to file a protective claim. Where to land on damages. How to phrase the demand so that it is firm without being inflammatory. All of that depends on the particular facts of the case and on experience of how cases like it have run.
This is the part of the case a generalist solicitor, an internet template, or a ChatGPT-generated letter cannot reliably do. Each of those produces a document that looks like a letter before action and contains the words a letter before action is expected to contain. What none of them can do is make the case-specific judgement calls that decide whether the letter actually works. Those calls come from a solicitor who has run the cases, lost some of them and learned from the losses, and seen enough of the same kinds of recipient to read the response coming.
There is also a credibility dimension. The recipient of a letter makes a quick judgement about the seriousness of the threat. A letter on the headed paper of a firm with a reputation for following matters through carries a different weight from a letter the recipient can tell, sometimes within a paragraph, the claimant put together alone or a non-specialist firm produced. That weight changes the response. A specialist firm with a visible track record is, in practical terms, part of the leverage the letter brings to bear.
For the same reason, when we run a defamation matter we tell the client realistically what the case is worth and what the realistic range of outcomes is. We do not promise certainty, because no one can on this kind of case. What we do is give the client a clear and honest read of the strengths, the weaknesses, the timeline and the cost, so that they can make informed decisions throughout. You can read more about the firm and what we do across defamation work on our internet defamation lawyers page.
Frequently asked questions about the letter before legal action in defamation
How long do I have to send a letter before legal action in a defamation case?
The strict deadline comes from the limitation period for defamation: one year from the date of first publication, under section 4A of the Limitation Act 1980. Within that one-year window, the protocol expects you to write a letter and give the recipient a reasonable time to respond, which is usually fourteen days. The closer you get to the one-year limit, the more important it is to take advice early, because options like filing a protective claim become relevant once the window is tight.
Can I draft the letter myself rather than instruct a solicitor?
You can, and some people do. The risk is that the calibration calls in the letter all carry consequences that follow the case for as long as it runs. Those calls include identifying the right defendant, drawing the line between fact and opinion, deciding what meaning the words carry, choosing what relief to ask for, and framing damages the right way. Getting any of them wrong at the letter stage produces a position that is then hard to revisit. Where the matter is serious enough that you are thinking about court at all, the cost of a specialist drafting the letter is usually smaller than the cost of the corrections later.
What can I do if I do not know who is behind the post?
You have three practical routes. Our in-house open-source intelligence team can identify the publisher from the traces they leave online, sometimes without any court order, and that is the first thing we try. Inside the UK, a Norwich Pharmacal Order against the platform can compel disclosure of subscriber data where in-house investigation does not get there. Where the platform sits in the United States, a section 1782 subpoena under US federal procedure can do equivalent work. We advise on which of the three routes fits the case.
What should the letter actually ask for?
A typical defamation letter before action asks for four things: the posts to be taken down, an apology in agreed terms, an undertaking not to repeat or republish the same or similar allegations, and damages. The way to handle damages is usually not to put a figure in the letter; the better approach is to set out the harm and to invite the recipient to make an opening offer. That puts the burden of making a financial proposal on them and tends to produce a more useful negotiation than naming a figure of your own.
How long does a defamation matter usually take from the letter to a result?
It depends on whether the recipient engages and on how serious the publication is. In a case like Red Rock Resources v Carp, which we have written up on our defamation by investors page, the letter, the pre-action correspondence and the issuing of a claim form together brought the case to settlement in approximately six weeks. Other cases take considerably longer, particularly where the recipient ignores the letter and the matter has to be litigated. The letter is what gives the case the best chance of resolving on the faster timeline.
What happens if the recipient ignores the letter before action?
If the recipient does not respond within the time given, or responds with a refusal to engage, the next step is to issue a claim form. In an identified-defendant case, that begins formal proceedings, with all the costs and case-management consequences that follow. In a persons-unknown case where you have not identified the publisher, you issue against persons unknown and the relief you seek, usually an injunction, comes through unopposed because the defendant cannot turn up to defend. Either way, the letter before action positions the case for what comes next.
