What Legal IT Companies Do

Document Management Systems

NetDocuments, iManage Work, and SharePoint are the main platforms for legal document management. These systems handle matter-centric filing, version control, email filing, and access controls that map to attorney-client relationships. The distinction between legal DMS and general-purpose document storage (Google Drive, Dropbox) is security, ethical wall enforcement, and attorney-client privilege metadata. IT companies that specialize in legal know how to configure these systems to meet bar ethics requirements.

Practice Management Software

Clio, MyCase, and Aderant are the leading practice management platforms. They handle intake, matter management, calendaring with court deadline rules, time tracking, billing, and trust accounting. IOLTA trust accounting compliance (proper separation of client funds from operating accounts) is a legal requirement in every US state, and software misconfiguration or data migration errors in trust accounts create bar licensing problems. Legal IT companies that migrate firms between practice management platforms need to understand this.

E-Discovery

Electronic discovery involves collecting, processing, reviewing, and producing electronically stored information (ESI) for litigation. Relativity and Nuix are the dominant platforms. E-discovery engagements can involve terabytes of data from corporate email servers, Slack, Teams, and mobile devices. The per-GB cost is high because processing involves deduplication, OCR, privilege review, and production formatting. Some legal IT companies run managed review centers; others provide the technology and process support.

Legal Billing and Time Tracking

BigTime, TimeSolv, and Tabs3 handle time entry, billing rate management, invoice generation, and AR. Large firms use Aderant Expert or Elite 3E. Integration between time tracking, billing, and the general ledger - while maintaining the matter-centric structure that law firms use - is different from standard accounting software deployment. A good legal IT company configures billing software to enforce billing guidelines (LEDES format for insurance defense work, for example) and integrate with client e-billing portals like LegalTracker or BillBlast.

Cybersecurity for Law Firms

The threat model for a law firm is different from a retailer. Law firms hold sensitive business information for clients - M&A deals, litigation strategy, trade secrets, employee records. Nation-state actors specifically target firms involved in major corporate transactions. Beyond standard endpoint protection and email security, law firms need ethical wall enforcement (information barriers between practice groups representing conflicting clients), encryption of all data at rest and in transit, and a tested incident response plan that includes client notification procedures under bar ethics rules.

Microsoft Copilot for Legal and AI Tools

Microsoft Copilot integrated with iManage or NetDocuments can draft correspondence, summarize deposition transcripts, and research across matter files. Harvey AI and CoCounsel (Thomson Reuters) handle legal research and contract analysis. Legal IT companies implementing AI tools need to configure data isolation so AI models trained on one client's data cannot surface in queries from another client's work - a confidentiality issue that general IT shops often miss.

Legacy System Migration

Time Matters, PCLaw, Amicus Attorney, and Juris are older practice management systems that many firms still use. Migration off these systems requires careful data extraction (some vendors make data export difficult), mapping legacy data structures to modern platforms, and verifying that trust account history migrates correctly. Getting this wrong has regulatory consequences.

Legal IT Project Costs

• Practice management platform implementation (Clio, MyCase): $5,000-$30,000 depending on firm size and data migration
• iManage or NetDocuments DMS deployment: $15,000-$80,000 for initial setup, configuration, and migration
• Legacy practice management migration (Time Matters, PCLaw to modern platform): $10,000-$50,000
• E-discovery platform setup and training (Relativity): $20,000-$100,000; per-matter processing costs additional
• Law firm cybersecurity assessment and remediation: $10,000-$60,000
• Microsoft 365 + Copilot for Legal deployment: $15,000-$50,000 for configuration and training
• Ongoing managed IT services for law firms: $200-$600 per user per month, depending on services included

How to Choose a Legal IT Company

1. Law firms are not standard business clients - verify legal-specific experience. Ask what percentage of their clients are law firms and which specific practice management, DMS, and billing platforms they have deployed. A general IT company that has "worked with a few law firms" is different from one where legal is their primary vertical.
2. Confirm they understand attorney-client privilege and confidentiality requirements. Ask how they handle data when troubleshooting - do technicians have access to client files? What is their clean-desk policy? Do they sign BAAs and engagement-specific confidentiality agreements? These are not unusual questions for legal IT vendors - a good one expects them.
3. Ask about Business Associate Agreement (BAA) readiness for any cloud vendor. If the firm handles medical malpractice, personal injury, or health care matters, PHI may be in client files. Any cloud vendor storing that data needs to sign a BAA. A legal IT company that does not raise this proactively is missing a compliance gap.
4. Verify their understanding of trust accounting system requirements. IOLTA trust account compliance is non-negotiable. Any migration or system change that affects trust account records needs to be handled with complete audit trail preservation and verified reconciliation. Ask specifically how they have handled trust accounting migrations in past projects.
5. Check their ethical wall implementation experience. Firms with conflicts of interest between practice groups need technical ethical walls (information barriers) enforced in DMS, email, and practice management systems. This is a specialized configuration requirement - not all legal IT companies have done it correctly.
6. Evaluate their incident response plan for a law firm context. A data breach at a law firm triggers state bar notification requirements in addition to standard breach notification laws. The IT company should have a plan that includes ethics counsel consultation as part of the response, not just technical remediation.
