Legal Tech for Law Firms: How to Choose a Platform

Choose legal tech by testing it against one real matter from intake to closing, then checking how it protects client data. A law firm should buy the platform that handles its own work and exceptions, keeps confidential information controlled and lets the firm leave with its data. Feature lists matter less than that test.

What should a law firm check first when choosing legal tech?

Start with one matter type and follow it from intake to closing. List who touches it, which documents it creates, which deadlines it carries and where the billing data ends up. That map tells you what the platform has to do, and it gives every vendor the same test.

We suggest picking the matter type with the most volume or the most missed steps. A plaintiff intake process and a corporate transaction need different things, and a demo built around a generic case will hide that difference.

Write the test down before the first demo. Then ask each vendor to run your matter, with your exceptions, on screen. Our guide to legal app features law firms need can help you build the feature list behind that test.

Which platform type fits your firm?

Most options fall into four groups. Many firms end up using more than one.

• Practice management: matters, calendars, time, billing and client records in one place. A common first buy for smaller firms.
• Document management: versions, search and access rights across large document sets. It matters more as matters and teams grow.
• Specialist tools: contract review, e-discovery, legal research or AI drafting. These do one job well but add another system to connect.
• Custom software: worth a look when your process gives you an edge or when packaged tools force costly workarounds.

Buy before you build when a packaged product covers your test matter with small changes. Build only the part no product handles well, and keep it connected to the system that holds your matter records.

How should you test client confidentiality and security?

Treat this as a pass or fail check, not a feature score. In its Formal Opinion 512, the American Bar Association tied lawyers' use of generative AI tools to existing duties, including competence, confidentiality, client communication and reasonable fees. The opinion is about AI, but the same questions apply well beyond it. State bar rules can differ, so have your own counsel confirm what applies to your firm.

Ask each vendor to answer these in writing:

• Who at the vendor can see client data, and under what conditions?
• Where is the data stored, and how is it encrypted?
• Can you limit access by matter, so an ethical wall actually holds?
• Does the audit log show who opened or changed a file?
• Can you export all your data and documents if you leave, and in what format?

A clear answer on export matters as much as the others. It sets your cost of leaving before you sign.

What should you ask about AI features?

Ask what the AI does with your data, and how a lawyer checks its output. The ABA's 2024 Legal Technology Survey found that 30% of responding lawyers used AI, ranging from 46% at firms with 100 or more attorneys to 18% among solo attorneys. The same report says three-quarters of respondents named concerns about hallucinations as the reason they held back.

Those concerns point to the right buying questions:

• Is client data used to train a model, and can you switch that off by contract?
• Does the tool show the source behind each answer, so a lawyer can check it?
• Who reviews the output before it reaches a client or a court?
• Can you turn AI features off by practice group or matter?

Fees need a decision too. The ABA's summary of the opinion says that in most circumstances a lawyer cannot charge a client for learning how to work a generative AI tool. Settle your billing policy before rollout. If you want a tool built around your own workflows, see our work on AI for law firms.

Which integrations does a law firm platform need?

Start with the systems your staff already keep open all day. For most firms that means email, calendar, document storage, accounting and e-signature. Then check each link for three things:

• Direction: does data move one way or both?
• Timing: does it update right away or on a nightly schedule?
• Failure: who gets told when a sync breaks, and how is it fixed?

Court deadlines and trust accounting deserve extra care, since a quiet failure there can cause real harm. Ask to see a failed sync in the demo. Where no ready connector exists, our API integration services team can build and monitor one.

How do you compare cost and plan the move?

Compare the total cost over three years, not the monthly seat price. Include setup, data migration, training, connectors, storage overage and any fee for exporting your data later. Then add the staff time needed to run the change.

Plan the migration as a project with its own owner. Move a sample of closed and open matters first, then check them with the people who use them. Counts alone will not show you a broken document link or a lost deadline. We cover that check in our post on reconciling a migration before cutover.

Run one practice group first. Set a date for the go or no-go decision, and name what must be true to continue. That gives partners a clear point to weigh in, and it keeps a weak fit from spreading across the whole firm.
