Frequently Asked Questions
What is the best document management system for law firms?
Smokeball is best for document automation and template-driven workflows. Clio is best for firms wanting document management integrated into practice management. NetDocuments is best for enterprise firms needing advanced security and compliance features.
Do law firms need separate document management software?
Small to mid-size firms (1-25 attorneys) can usually rely on the DMS built into their practice management platform (Clio, Smokeball, MyCase). Firms with 25+ attorneys or strict compliance requirements (banking, M&A) often benefit from a dedicated DMS like NetDocuments alongside their PM tool.
How secure is cloud-based legal document management?
All three platforms (Smokeball, Clio, NetDocuments) use AES-256 encryption, SOC 2 compliance, and role-based access controls. NetDocuments adds ethical walls and granular document-level permissions for the most sensitive matters. Cloud storage is generally more secure than local servers for most law firms.
Can legal document management software automate document creation?
Yes. Smokeball leads with 20,000+ templates that auto-fill from matter data. Clio and MyCase also offer document templates with variable fields. This automation typically saves 30-60 minutes per document compared to manual creation.
