Good preparation reduces hearing time, lowers costs and minimises surprises. This guide provides a step by step practical checklist for parties, solicitors and witnesses in England and Wales. It covers document management, disclosure, witness statements, expert evidence, electronic evidence, hearings bundles, rehearsals and procedural compliance. The guidance reflects the Arbitration Act 1996 and common institutional practices and aims to help clients present clear, persuasive and proportionate evidence.Plan the evidence strategy earlyDefine the issues to be decidedStart by identifying the legal and factual issues the tribunal must decide. Map each issue to the evidence needed to prove or disprove it. This reduces unnecessary disclosure and focuses preparation on the points that matter.Set objectives and key themesAgree the case narrative and three to five core themes that the party wants the tribunal to accept. Build evidence around those themes so witnesses and experts support the main arguments consistently.Create an evidence timetablePrepare a timeline for document collection witness statements expert reports disclosure and bundle preparation. Set internal deadlines well before tribunal directions to allow for review, redaction and challenge handling.Document management and preservationIssue a preservation noticeWhen a dispute arises, send a written notice to preserve documents and electronic data. A preservation notice should identify the types of documents to retain, custodians and relevant timeframes. Early preservation avoids later accusations of spoliation.Collect key documents promptlyIdentify and secure primary documents such as contracts invoices emails meeting minutes design drawings service logs and financial records. Prioritise documents that prove core elements like breach causation loss and notice of claim.Use a defensible processDocument collection should follow a clear, defensible process. Record search parameters, custodians, search dates and any deletions or overwrites. Document the steps taken to locate archived or backup data so the tribunal sees that reasonable steps occurred.E-discovery and proportionalityAgree proportional search termsPropose focused search terms and custodians to limit the volume of electronic discovery. Use date ranges and specific keywords tied to the dispute issues. Narrow searches reduce cost and avoid irrelevant results.Use technology assisted review where appropriateFor large datasets use technology assisted review tools to prioritise documents for human review. Machine learning and concept searching can reduce review hours while maintaining quality. Document the methodology so opposing parties and the tribunal can assess proportionality.Handle privileged material carefullyIdentify privileged documents early and segregate them. Apply privilege logs that show document type date sender recipient and the basis of privilege without revealing the privileged content. Updated privilege logs help resolve disputes about scope while protecting sensitive communications.Disclosure obligations and practical stepsUnderstand the tribunal\u2019s disclosure regimeFollow the tribunal\u2019s directions on disclosure. Parties should propose a disclosure plan that lists categories of documents, timeframes and any search protocols. A proportionate plan reduces disputes about breadth and preserves resources.Produce core documents firstDeliver key documents that prove the primary case elements early. Early production avoids surprise at the hearing and allows time for challenge, witness preparation and expert analysis.Manage confidentiality and redactionApply agreed confidentiality bands such as highly confidential commercially sensitive and non confidential. Use redaction judiciously to protect trade secrets personal data or privileged material while allowing the tribunal and opposing party to assess the case.Witness preparation and statementsSelect the right witnessesIdentify witnesses who provide first hand knowledge of facts central to the dispute. Prefer witnesses with direct involvement rather than those who provide hearsay or second hand accounts. Consider corporate witnesses, project managers, technical staff and external contractors.Draft clear witness statementsDraft statements that set out facts chronologically and link to documents in the bundle. Use plain language and short paragraphs. Witness statements must state the witness\u2019s role, how they know the facts and any documents they rely on. Avoid argument and legal submission in witness evidence.Verify and sign statements properlyEnsure each witness signs a statement of truth where required by the tribunal rules or the seat. Confirm the witness understands the statement and has an opportunity to review the documents cited. Signed statements strengthen credibility and withstand challenges.Prepare witnesses for cross examinationRehearse likely cross examination themes and questions. Train witnesses to answer briefly to the point and to pause before responding to complex questions. Emphasise honesty: witnesses should not speculate beyond their knowledge and should say \u201cI do not recall\u201d when appropriate.Expert evidence: selection and managementChoose experts with the right instructionsSelect experts with relevant technical qualifications experience and independence. Provide a clear instruction letter that outlines the tribunal\u2019s remit the issues to be decided document references and the format required for the report.Agree the scope and procedure earlyWhere possible agree the expert scope, timetable and procedures including joint expert meetings or concurrent evidence. Tribunals often favour single joint experts or hot tubbing to reduce duplication and streamline evidence.Ensure expert independence and complianceExperts must act independently and follow applicable professional guidance and the tribunal\u2019s directions. Experts should include a statement of independence and disclose any previous involvement with the parties that might create perceived bias.Draft clear, focused expert reportsExpert reports should be concise, structured and confined to matters within expertise. Each opinion should state the assumptions, methodology and any material relied upon. Address alternative views and explain why the expert prefers the chosen conclusion.Use expert meetings to narrow issuesExperts can meet to identify areas of agreement and disagreement and produce a joint statement of issues. This process reduces hearing time and makes it easier for the tribunal to identify the real scientific or technical disputes.Electronic evidence and witness statementsPreserve metadata and originalsKeep original electronic files and preserve metadata where possible. Metadata can show document creation, modification and access patterns which often prove authenticity and chronology.Authenticate electronic evidenceLink electronic documents to witness statements that explain origin, custodianship and relevance. Where authentication proves contentious obtain affidavits or witness testimony from IT staff or custodians to verify chain of custody.Manage encrypted or archived dataPlan ahead for access to encrypted servers cloud storage or legacy systems. Early IT work prevents last minute delays and allows time to recover backups where needed.Preparing the hearing bundleFollow tribunal directions for bundlesTribunals issue directions on bundle format pagination and indexing. Follow those directions exactly to avoid objections. Early compliance saves time during the hearing and reduces procedural wrangling.Indexing and cross referencingCreate a clear index with bundle numbers, document descriptions and dates. Cross reference documents in witness statements and expert reports to bundle pages so tribunal members and opponents can check sources quickly.Use electronic bundles and navigation aidsProvide searchable electronic bundles with bookmarks and links between statements, documents and expert reports. Electronic bundles speed hearings and enable instant reference during cross examination. Provide the tribunal with both electronic and paper copies where required.Hearing logistics and rehearsalsRun a mock hearingConduct a full rehearsal that simulates the hearing. Practice opening submissions witness examinations and expert questioning. Rehearsals reveal timing issues weaknesses in facts and problems with exhibits.Plan witness logisticsSchedule witness attendance, travel and availability for remote hearings. Confirm witnesses can access electronic bundles and have the necessary technology for remote testimony. Prepare contingency plans in case a witness becomes unavailable.Prepare opening and closing submissionsPrepare concise opening submissions that set out the issues, evidence roadmap and relief sought. Closing submissions should summarise key evidence and address weaknesses candidly while emphasising strengths. Keep submissions focused on the tribunal\u2019s decision needs.Manage hearings with technologyTest audio visual systems, screens and remote platforms in advance. Prepare electronic presentation materials and ensure exhibit links work. Have IT support available during the hearing to deal with connectivity or display issues.Handling objections and procedural pointsAnticipate jurisdictional or procedural challengesOpponents may raise jurisdictional defences, challenges to admissibility or complaints about disclosure. Prepare procedural responses and consider provisional arguments so the tribunal can decide efficiently.Deal promptly with late evidenceIf new evidence surfaces late, assess whether it genuinely affects the outcome and whether the tribunal should admit it. Propose limited processes for testing new evidence such as short witness statements, limited cross examination or a narrow further disclosure order.Addressing hearsay and admissibilityExplain hearsay necessity and reliabilityWhen primary witnesses cannot give oral evidence explain why the tribunal should accept hearsay such as business records or contemporaneous emails. Provide supporting material that shows the document routine origin and reliability.Cross refer to rules and legal authorityWhen arguing admissibility cite the relevant institutional rules the Arbitration Act 1996 or case law. Clear legal reasoning helps the tribunal accept documents and testimony while keeping focus on the factual dispute.Record keeping and post hearing tasksMaintain a hearing logKeep a detailed log of hearing events, applications made, rulings given and any agreed undertakings. A hearing log assists cost recovery arguments, enforcement of orders and any later challenges.Prepare for award draftingProvide the tribunal with clear schedules of damages calculations, legal submissions on remedy and proposed wording for orders the party seeks. Accurate schedules speed award drafting and reduce correction requests.Archive and secure documentsAfter the hearing secure all documents, witness statements and electronic bundles in a secure archive with restricted access. Maintain chain of custody records and preserve originals in case of enforcement or appeal.Practical tips to reduce risk and costFocus on core documents onlyLimit disclosure and bundle scope to the documents the tribunal needs to decide the case. Reducing volume saves cost and helps the tribunal focus on the key evidence.Use clear, plain languageDraft witness statements and expert reports in plain language with short paragraphs and signposting. Clear writing reduces misinterpretation and helps the tribunal follow complex arguments.Manage expert costsAgree expert budgets and limit expert pages and hearing time. Use single joint experts where appropriate to avoid duplication and rule out unnecessary expert panels.Keep communication professional and documentedKeep all communications with opposing parties and third parties professional and documented. Avoid informal evidence exchanges without written confirmation to prevent later disputes.ConclusionThorough preparation of evidence determines the quality and speed of an arbitration hearing. Parties who plan early, preserve documents, manage disclosure proportionately and prepare witnesses and experts carefully present stronger cases and reduce cost. Clear bundles, rehearsed presentations and effective use of technology improve hearing efficiency and help the tribunal reach a reasoned award. Following the checklist above gives parties in England and Wales a disciplined structure to prepare evidence, reduce surprises and maximise the chance of a favourable result.Brief summary– Identify legal and factual issues and map evidence to each issue. – Issue preservation notices and collect key documents promptly. – Use proportionate e discovery with focused search terms and technology assisted review. – Protect privilege with clear privilege logs and segregation. – Prepare concise witness statements and rehearse witnesses for cross examination. – Instruct independent experts, agree scope early and use joint statements where possible. – Preserve and authenticate electronic evidence including metadata. – Create well indexed electronic and paper hearing bundles with cross references. – Rehearse the hearing, test technology and plan witness logistics. – Maintain a hearing log, secure post hearing archives and support award drafting.At Alexander JLO we have many years of experience of dealing with all aspects of law and will be happy to discuss your case in a free no obligation consultation.
