Memorials, Briefs and Pleadings in UAE Arbitration

How each written submission in a UAE arbitration works — the statement of claim, the statement of defence, reply briefs, full memorials and post-hearing briefs — and what tribunals expect from each.

Written submissions are where a UAE arbitration is won or lost, because the tribunal forms its view of the dispute from the written record long before the hearing. This guide takes each document in the order it arrives, explains the job it does, and sets out the drafting choices that make a case easier for a tribunal to follow.

Written submissions carry the case in a UAE arbitration. Whether they are called memorials, briefs or pleadings, these documents are how each party sets out what happened, what the contract and the law require, and what it wants the tribunal to order. They are not formalities. In most arbitrations the tribunal forms its working view of the dispute from the written record long before anyone stands up at a hearing, so the way a submission is drafted has a direct bearing on the award.

Drafting them well calls for command of two things at once: the procedural rules that govern the reference, and the substantive law that decides the claim. Arbitration gives parties more freedom over procedure than court litigation does, and that freedom shifts responsibility onto counsel. Nothing prompts you to plead a point in the right document at the right time. A statement of claim, a statement of defence, a reply, a memorial and a post-hearing brief each do a different job at a different stage, and an argument raised in the wrong one risks being treated as an afterthought.

The UAE setting adds a further layer. Arbitration here sits where a civil law tradition meets international arbitration practice, so counsel have to work comfortably with institutional rules such as those of the Dubai International Arbitration Centre (DIAC) and the International Chamber of Commerce (ICC), alongside the UAE Federal Arbitration Law (Federal Law No. 6 of 2018). Tribunals are frequently mixed in legal background. A submission written only for a UAE reader, or only for a common law one, tends to lose part of its audience.

What follows takes the written submissions used in UAE arbitration in the order they normally arrive — statement of claim, statement of defence, reply briefs, memorials and post-hearing briefs — and then turns to the drafting choices that make each of them easier for a tribunal to follow and harder for an opponent to unpick.

What the statement of claim has to establish

The statement of claim is the first substantive submission and the one that frames everything after it. It has to set out the facts, the legal basis for each claim and the relief sought, with enough detail for the tribunal to see the case and few enough side issues for it to stay in view. Long is not the same as strong. A claim that buries its best point in the twentieth paragraph of background invites the tribunal to find that point on its own, and it may not.

Procedurally, the statement of claim has to satisfy the applicable arbitration rules and the UAE Federal Arbitration Law. In practice that means identifying the parties, describing the dispute, stating the legal basis of the claim, and quantifying the damages or specifying whatever other remedy is asked for. A claimant who treats that list as a checklist produces a compliant document. A claimant who treats it as the first chance to argue produces a useful one. Known weak points are better acknowledged and answered here than left for the respondent to raise first.

The statement of claim also fixes the scope of the dispute. By choosing which claims to bring and how to characterise them, a claimant decides what the arbitration is about, which legal framework applies and which documents will matter. That framing repays real attention in UAE arbitration, where tribunals reward a clearly ordered case and where a respondent will often try to widen the issues to dilute a strong claim.

Enforcement deserves thought at this early stage as well. Arbitration awards in the UAE are subject to enforcement under the New York Convention and local law, and the coherence of the pleaded case affects how readily an award is recognised and executed. A claim that is vague about what was breached, or about how the sum claimed was calculated, hands a losing party material for a challenge later.

The statement of defence and the reply brief

The statement of defence is where a respondent answers the case as the claimant has actually pleaded it: meeting each allegation, disputing the facts on which it rests, and testing the evidence relied on. Respondents regularly face claims drafted to look broader and stronger than they are, which is why an effective defence does more than deny. It answers the claim and puts the respondent’s own account of the dealings in front of the tribunal.

The most workable defences follow the order of the claim, so that every allegation is admitted, denied, or admitted in part with an explanation. The respondent should also plead positive defences where they exist, such as objections to the tribunal’s jurisdiction or irregularities in the procedure followed, either of which may end the case early or narrow what remains. The arbitration rules and the Federal Arbitration Law leave room to raise objections of this kind, but when they are raised matters as much as how: a point held back for tactical reasons can cost the respondent procedurally.

Reply briefs then give the claimant an opportunity to deal with what is genuinely new in the defence — an unexpected factual account, a defence not anticipated, a document produced for the first time. A reply that restates the claim wastes the opportunity and irritates the tribunal. A reply that answers the new material, concedes what is not worth fighting, and holds the original case together keeps the claimant in control of the narrative, and it should be written with the respondent’s likely answer already in mind.

The exchange between defence and reply usually settles the shape of the arbitration. By the end of it, the real points of disagreement are visible, the common ground is marked out, and the tribunal has begun to see which issues it will have to decide. Counsel who use that exchange to sharpen the dispute rather than enlarge it tend to reach the hearing with a case the tribunal can hold in its head.

Memorials and post-hearing briefs

A memorial is a full statement of a party’s case in a single document, bringing legal argument, documentary evidence, witness statements and expert material together. Memorials are usually filed at set stages of the arbitration, such as after the opening pleadings or following the evidentiary hearings, and they are the document a tribunal is most likely to read from beginning to end. Everything a party wants relied on should be inside it or clearly referenced from it.

Drafting one is largely a question of method. Counsel have to organise the document so that a reader can move through it: clear headings, a short summary of the case at the front, issues grouped by theme rather than by the order in which they happened to arise, and cross-references that work. That discipline keeps a long submission readable. Memorials in the UAE may also need to address points of local law and principles drawn from international arbitration practice in the same breath, which asks something of both the analysis and the drafting.

Post-hearing briefs do a narrower job. Filed after the oral hearings close, they let a party draw out what the evidence actually established, answer the case opposing counsel put orally, and clear up any question the tribunal raised from the bench. They are the last word before deliberation, which makes them the place to show where the other side’s witnesses shifted position and where your own documents were never seriously challenged.

Both memorials and post-hearing briefs read better in a measured tone. Arbitration is adversarial, but the tribunal is an impartial decision-maker, and submissions that lean on indignation rather than analysis lose credibility with the people who decide the case. Precise legal reasoning and a clear account of the facts persuade; rhetoric about the opponent rarely does.

Drafting choices that persuade a tribunal

First, hold to one case theory across every document. A tribunal reading the claim, the reply and the post-hearing brief should meet the same explanation of the dispute each time, developed further but never quietly changed. Identify the two or three issues the case turns on at the outset and keep them at the front of every submission, so the tribunal always knows what it is being asked to decide.

Second, answer the other side’s case before it is made. Counterarguments, gaps in the evidence and jurisdictional points are all better dealt with in your own submission, on your own terms, than conceded under pressure at a hearing. Arbitration rewards the party that is candid about the difficulties in its case, because a tribunal that has been told about a weak point is less troubled by it than a tribunal that discovers one.

Third, write plainly and formally. Arbitrators in UAE proceedings often come from different legal systems and read in a second or third language, so sentences should be short enough to be read once, terms should be used consistently, and defined expressions should keep the same meaning from the first submission to the last. Clear drafting also supports the award itself, since ambiguity in the submissions can carry through to the reasoning and complicate recognition.

Fourth, tie every piece of evidence to the argument it supports. Exhibits filed without explanation, or a witness statement left to speak for itself, put work back on the tribunal that counsel should have done. Each factual assertion should point to the document or witness that proves it, and each legal conclusion should point to the facts it rests on. Submissions built that way let a tribunal follow the case from the first page of the claim to the relief sought.

Conclusion

Written submissions in UAE arbitration are where the case is actually built. Memorials, briefs and pleadings set out the facts and the law, answer what the other side has said, and keep the dispute in a shape the tribunal can decide. The UAE setting, drawing on both a civil law tradition and international arbitration practice, asks counsel to combine close legal analysis with a clear sense of where the case is going.

The parties that fare best are the ones that plan the written record as a sequence rather than filing documents one at a time. Each claim and each defence is framed to limit surprises and to make the case plain. Precise language, arguments in a logical order, and evidence tied to the points it supports improve the prospects in the arbitration itself and make the resulting award easier to enforce in the UAE and elsewhere.

For any party in a UAE arbitration, the time and expertise put into the written submissions is not overhead. These documents form the backbone of the proceedings and shape the tribunal’s decision. Counsel who know the applicable UAE arbitration rules and can draft to them are the difference between a case a tribunal can follow and one it has to reconstruct.
