Delium Pre-Trial Tools That Make a Difference
Seamless Imports, Exports & Reporting
Delium makes importing, exporting and reporting fast, accurate and stress-free, ensuring litigators have the right evidence at the right time. Delium supports bulk data imports from other litigation platforms, industry standard Excel or MS Access files via an atomic transaction wizard plus a .zip file of corresponding documents. Before import, Delium validates all data to ensure compliance with case requirements. If issues arise, a detailed report identifies necessary corrections. Once validated, users receive an email confirmation of the completed import. Users can:
- Perform Full Imports – Add entirely new documents
- Use Custom Updates – Modify existing data or replace document images without reimporting
For smaller updates, Delium allows single-document uploads, with metadata entered at the time of upload or added later.
Exports from Delium are available in Excel or MS Access for smooth integration with litigation tools. Additionally, Delium offers pre-configured reports in Excel or PDF, providing insights into case progress and document activity.

Powerful Search Tools: Pinpoint Powerful Documents
Delium’s powerful search tools help litigators quickly pinpoint critical documents, refine case strategies and stay ahead in trial preparation – ensuring no key piece of evidence is missed.
Delium provides three search modes to accommodate different levels of complexity:
- Simple Search – Enter a word or phrase without specifying where it appears in the document
- Template Search – Use structured “AND” searches to refine results
- Advanced Search – Apply Boolean operators to create complex, nested search logic
Searches can be performed across metadata fields, document text (OCR) including emojis 😊 or both, with user permissions controlling access to full document collections or only those released for legal analysis.
Delium gives litigators advanced control over their searches, allowing them to filter results by file type, presence of redactions or annotations, and whether documents are hosts or attachments. The built-in Indexed Words Thesaurus helps uncover related terms, ensuring no key evidence is missed. Users can instantly highlight search hits for faster review and customise how results are displayed – sorting by date, document type, folder hierarchy or other metadata fields for more efficient analysis.

Smart Analysis & Evidence Organisation
Delium’s advanced analysis tools streamline pre-trial preparation by helping litigators efficiently review, annotate, organise and cross-reference evidence.
Users can tag and bundle documents using a range of Hierarchy fields – ideal for managing witness statements, expert reports or issue-specific collections to track critical insights across their case.
Subscribing to key documents ensures automatic email alerts when new analysis or updates occur, keeping teams informed and trial ready.
Delium also connects related documents by automatically generating hyperlinks between Expert Reports, Transcripts, Pleadings and Witness Statements using editable Regular Expressions. These links can be based on document IDs, exhibit numbers or text references added manually and color-coded to reflect different relationships. When hyperlinks are present, Delium opens the document in a side-by-side view making it easy to follow connections and review linked evidence without switching screens.

Comprehensive File Type & Language Support
Delium ensures litigators can seamlessly view, analyse and present evidence across a wide range of file types and languages, eliminating compatibility issues and technical barriers. With built-in multilingual and multimedia capabilities, Delium provides fast, reliable access to case materials, enabling efficient pre-trial preparation.
The zero-footprint Delium Viewer supports over 100 file formats for near-native viewing, annotation and redaction – no additional software required.
With UTF-8 and ISO UCS-2 encoding, Delium processes and displays multilingual text, supporting scripts from the Americas, Europe, Middle East, Africa, Asia and the Pacific, ensuring documents in multiple languages can be effectively searched and analysed.
Delium also supports all HTML5-compatible audio and video formats, with built-in accessibility features to ensure clear and efficient evidence review, including:
- Subtitles – Display spoken content for translation or accessibility
- Closed Captions – Include dialogue, sound effects and speaker identification
- Custom Poster Images – Show a video preview before playback
- Navigation Controls – Quickly jump to specific points in media files
- Offline Viewing – Download content for review anytime, anywhere
With Delium, litigators can work with diverse evidence formats effortlessly, ensuring critical information is always accessible, easy to review and ready for presentation.

Effortless Annotation & Redaction
Throw away your highlighter — Delium makes annotation fast, precise and highly customisable, helping you clearly mark and organise key details. Redaction is just as efficient, with powerful tools to securely remove sensitive information when needed.
With 10 annotation types in 27 colours, you can highlight, add notes or draw attention to critical details. Annotations can be categorised by issue, made private or team-visible, and are fully searchable. Options include highlights, colour-coded notes, shapes and lines, and strikethroughs to show edits while preserving context. Delium also validates your hyperlinks, generating an Excel report of valid and broken links, and flags each with a tick or cross for easy reference.
For redaction, Delium enables quick, bulk removal of sensitive information using pre-defined regular expressions.
All annotations and redactions can be exported to PDF, making them easy to reference and share.

Alias Management: Simplify People & Entity Tracking
In legal disputes, people and organisations are often referred to by different names, making it difficult to track all relevant documents.
Delium’s Alias Management Module eliminates this challenge, ensuring no critical connections are missed by linking all name variations under a single alias for fast, comprehensive searches.
Instead of manually searching for multiple email addresses or name variations, simply enter ‘Joe Bloggs’ and Delium will retrieve every related document – even if they are also referred to as ‘J. Bloggs’ or ‘[email protected]’.
Aliases can also group multiple individuals or organisations, such as members of a team or a parent company and its subsidiaries, making it easier to analyse relationships and ensure all relevant evidence is considered.

Chronology Manager: Build & Import Case Timelines with Ease
Delium’s Chronology Manager provides an intuitive way to organise case events, whether manually or via bulk import, ensuring litigators can efficiently build, track and analyse evidence-backed case timelines.
Each chronology entry consists of:
- An Event Name – The key occurrence in the case timeline (required)
- A Date – When the event took place (optional)
- An Abstract – A description providing context for the event (required)
- A Document Reference – Supporting evidence linked to the event (optional)
- Review Status – Track whether an event has been reviewed
Events exist independently of specific chronologies, meaning they can be applied to multiple timelines without duplication.
A Chronology Report can be generated to Excel or PDF including automated hyperlinks to the referenced evidence.

Stay Updated with Key Document Tracking
Delium ensures you never miss critical case developments, even when you’re not logged in. Simply click the Key Document star icon next to a Document ID in the Delium Viewer to subscribe or unsubscribe from updates or manage subscriptions through the Key Document module. You can also subscribe team members who need to stay informed.
Once subscribed, Delium automatically tracks changes to key document fields, such as privilege status, and sends a single daily email alert so you’re always up to date. This feature fosters collaboration but eliminates the need for constant manual checks, ensuring your team stays informed and aligned – even when they’re out of the office.
