 How to implement new legal tech


Legal tech enhances every part of a law firm’s operations. Substantial benefits are found everywhere that you look.

Productivity, workflow, and client service are among the ways that legal tech can provide a generational upgrade to a law firm:


Greater productivity

Legal technology allows lawyers to perform routine tasks more quickly and easily. For example, a lawyer can complete a court document much faster thanks to having access to a large database of standard templates and forms. Legal work can be streamlined and improved in a myriad of similar ways.


Optimized workflow

Lawyers need to communicate quickly and securely with colleagues in order to complete complex legal work efficiently. The use of document and business management tools providing a single source of truth helps your firm build step-by-step processes, create easy-to-use checklists for routine tasks, and help lawyers stick to hard deadlines.


Improved client service

Clients usually want to feel involved in their cases. Now there are easier, yet more comprehensive, ways to keep them in the loop. An online client portal, for example, can serve as the client’s and business partners’ base of operations—a place where they keep tabs on their case’s progress and share documents.

Installing new legal tech means a substantial investment, to be sure. But the many benefits of new legal technology products will outweigh the implementation costs. More efficiency, reduced costs, and streamlined processes add up to one fundamental improvement: more focus on your business partners and clients.

The better and more efficient your services become, the more your legal organization’s reputation will grow. More business will soon follow.


Whether your team needs new legal research tools, productivity solutions, financial management tools, or investigative and compliance solutions, many products are now available to give your organization the boost it needs.

Application: Legal practice management


Use case — Data management

Consider knowledge management tools as something like a highway improvement for your firm’s document management system. Systems will provide accurate and comprehensive results to legal questions within seconds.

Documents get automatically categorized, and all users can see where in the case process each document is—who has reviewed it, who has edited it, who has yet to sign it, and so on. As the tool is typically compatible with a suite of other products, this enables users to access multiple databases with a single query.


Use case — Law firm growth

A variety of applications help a law firm run its practice more efficiently. Legal business management and operations tools foster better team collaboration with access to a wide span of legal information and business data. Business development tools enable lawyers to provide an ideal client experience by streamlining communication and requests for all their legal needs through an easy, secure and customizable digital portal.

Application: Transaction management


Use case — Due diligence

Due diligence once meant that junior lawyers spent their weekends at the office sifting through boxes of paperwork. Now via due diligence tools, lawyers can conduct diligence in a paperless environment, able to virtually access a host of databases, whether it’s corporate filings, FEIN numbers, or dockets.

AI-powered systems swiftly analyze this information, retrieving all pertinent information and presenting the findings in an easy-to-digest format.


Use case — M&A due diligence

M&A due diligence technology fully automates the diligence process from uploading documents, to analysis and classification of all relevant data, to producing charts and summaries.

For instance, when a lawyer needs to search a seller’s documents for non-compete employee agreements, M&A due diligence tech allows them to do so with unprecedented speed and efficiency. AI is also changing every aspect of this process.

Use case — Matter management

Streamline operations management to achieve cost savings. By using AI, legal corporate departments can create a centralized source for legal matter details throughout the matter’s lifecycle.

Automated review and approval of invoices speeds up workflow; auditing tools improve accuracy and reduce errors. Legal departments can analyze their bidders’ rates and benchmark their rates against their own real-time data.


Use case — Tracking outside counsel spend

One way to slash outside counsel costs is to have a more accurate means of measuring your spend. Spend management tools lets a firm pinpoint ways to achieve savings — for example, giving users rough estimates of what peer companies do for outside counsel spend, thus comparing your costs with theirs. The use of automated invoice workflows and auditing tools also further reduce counsel spend.

You may feel overwhelmed once you begin to research legal solutions. A great thing about the variety of applications currently available is that a law firm can customize its own tech stack. But a problem with this, however, is that many firms feel there’s too much choice. They worry about investing in systems that won’t prove to be the right fit for them and get lost in the sheer number of options out there.

So here are some initial questions to ask when your firm is looking to upgrade its legal tech. Use the answers that you get to lead you towards the applications that will be the best fit for your firm.


Identify your most vital needs?

Ask yourself:

  • What do you do now at your law firm, and how?
  • What issues are causing you unnecessary stress?
  • In what areas do you feel you’re dangerously lagging your direct competitors?
  • What are your biggest cost centers?
  • What do your clients say they want most from you?

Research legal solutions

There’s an overwhelming amount of legal technology options. Look at the current tech landscape and get your network’s opinions on what they use. Talking to those who are in the know can provide better insight rather than solely getting product demos.



Investing and installing new legal technology is a big project. You may need external help to help your firm set up, run, and maintain the new solution. Consider hiring someone who can properly implement it and teach you how to use it.


Get buy in by ensuring people and processes can adapt

New technology is a boon to a law firm. But its benefits will be limited if a firm’s lawyers are unclear how to use it or are resistant to using it.

Ensuring that a new system is easy to use, with intuitive prompts that reduce the need for training, and causes minor disruption to a lawyer’s workday, will go a long way towards helping lawyers buy into the new systems. After all, lawyers are busy—asking them to master a new technology suite in their “downtime” could be a source of discontent.

Technology is driving the legal industry more than ever before. By investing in newer solutions, your firm will become more efficient, more productive, and of greater value to your clients.
