When Legal Knowledge Grows Faster Than Lawyers Can Search
A leading law firm in Singapore manages hundreds of thousands of historical legal cases across multiple jurisdictions. Lawyers regularly need to search for relevant precedents, but legacy search systems struggle to deliver accurate results.
The firm partnered with DEHA GLOBAL to transform its legal knowledge base using Legal AI Fine-tuning.
Traditional Legal Search Cannot Handle Legal Complexity
The firm relied on a legacy case management system with basic keyword search capabilities. As the database grew, the system showed clear limitations:
- Search results returned too many irrelevant cases
- Lawyers had to manually read through dozens of documents
- Search performance slowed significantly as data volume increased
- Similar cases were often missed due to differences in wording or jurisdiction
- Valuable institutional knowledge remained underutilized
As a result, lawyers spent significant billable time searching instead of analyzing, directly impacting productivity and service quality.
The firm needed an AI solution that could understand legal language, legal context, and legal reasoning — not just keywords.
Fine-tuned Legal AI Built on the Firm’s Own Case Data
DEHA GLOBAL designed and delivered a Legal AI Fine-tuning solution, transforming a generic Large Language Model (LLM) into a domain-specific legal intelligence assistant.
Instead of training a model from scratch, DEHA GLOBAL applied fine-tuning techniques using the firm’s historical legal cases and internal documents.
- Data Preparation & Structuring
Hundreds of thousands of legal documents were cleaned, structured, and categorized by:
+ Case type
+ Jurisdiction
+ Legal domain
+ Outcome and reasoning
- Model Selection & Fine-tuning
An open-source LLM was selected and fine-tuned using the firm’s proprietary data, enabling the model to:
+ Understand legal terminology
+ Capture legal logic and context
+ Recognize similarities beyond keyword matching
- Legal AI Chat Interface
Lawyers can now chat with the AI:
+ Describe a case in natural language
+ Ask for similar precedents
+ Request summaries of relevant past cases
- Enterprise Deployment
The system was deployed on secure infrastructure, ensuring compliance with strict legal and data protection requirements.
From Manual Search to Instant Legal Intelligence
After deployment, the firm experienced a fundamental shift in how legal knowledge was accessed.
For Lawyers
- Relevant case references returned within seconds
- Drastically reduced time spent searching archives
- Ability to focus on legal analysis and strategy
“The AI doesn’t just search — it understands what my case is really about.”
A senior associate commented
For the Law Firm
- Thousands of lawyers are supported daily by a single AI platform
- Consistent access to institutional knowledge across offices
- Improved quality and speed of legal advice
- Better utilization of historical case assets
The firm effectively converted decades of legal experience into a scalable digital legal assistant.

- System Integration & Deployment: 4–6 weeks
Total Implementation Time: ~5–6 months
Cost Consideration (Indicative)
Project cost depends on:
- Volume and complexity of legal documents
- Number of supported users (lawyers, offices)
- Deployment model (private cloud / on-premise)
- Compliance and security requirements
Typical Legal AI Fine-tuning projects start from a high five-figure to low six-figure USD range, delivering ROI through:
- Increased lawyer productivity
- Faster case preparation and response
Why Legal AI Fine-tuning Matters for Law Firms
This use case demonstrates how fine-tuned AI can outperform generic AI tools in highly specialized, high-stakes domains.
For law firms, Legal AI Fine-tuning enables:
- Precision over generality
- Knowledge scalability without hiring more staff
- Competitive differentiation through proprietary data
AI becomes not just a tool, but a strategic knowledge asset.
