Artificial intelligence and law firms – what does it all mean?

artificial intelligence and law firmsArtificial intelligence and law firms is certainly a phrase batted around frequently nowadays. Yet, does anyone really know what it means? I took a look at this question a couple of years ago but, since then, things have moved on.

Artificial intelligence is a generic term for a whole ragbag of technologies, system architectures and software. I have yet to meet two people who have given it the same definition. Confused? – you will be!

To unravel the conundrum, let’s not focus on technologies. Instead, let’s take a look at here now capabilities and how they are being applied effectively in the legal workplace.

The bottom line for artificial intelligence and law firms is straightforward. It has to be capable of doing the job as well as a human or better, without excessive human intervention.

AI that’s already here.

If you take that definition literally, there’s plenty of AI in legal offices now. Consider the following:

Practice management systems.

Yes, even your humble practice management system is a form of AI. The best ones manage your billable hours in the background without the need for tedious, month-end routines. This is just the tip of the iceberg. These systems automate many other aspects of administration including VAT returns and quarterly and annual firm accounts. They remove the drudgery by simple automation.

Due diligence.

In the same manner, AI can carry out due diligence much more quickly than legal staff. It also has the potential to eliminate human error.

Reviewing contracts.

There are AI systems around that can review contracts. They operate by drawing attention to any aspects or clauses that appear unusual. This allows legal professionals to focus on the salient points leading to better use of time. In addition, it reduces the human error factor.

Big data.

Big data is another buzzword. Essentially it means the ability to process large amounts of data (beyond the capability of humans) to deliver a result. This is particularly valuable in the legal sector where there is a vast databank of precedents and past cases.

AI speeds this process dramatically to provide law firms with information to determine how they should proceed. Lex Machina is one such product that can already assess the likelihood of winning a case as soon as the initial documentation is received.

Dispute resolution.

There isn’t really an AI product for dispute resolution available at the moment. However, many commentators, including Richard Susskind, believe it is just around the corner. Richard is a strong advocate of virtual courts and in his recent books he calls for a “global online court revolution”.


Much of the above may appear pie in the sky to a small, High Street practice. Yet, a recent CBRE study of London law firms showed that 48% are already using artificial intelligence, and 41% plan to do so soon. If past IT trends are followed, it won’t be long before it trickles down from the Magic Circle.

Existing AI is tailored towards improving the speed, efficiency and accuracy of mundane and repetitive jobs. The bonus is that this leaves you free to concentrate on what you are good at – being a lawyer. The real issue is not the apocalyptic idea of replacing humans with machines. It’s about how AI can support the legal profession and, in doing so, provide a better client experience. And, of course, it won’t have escaped the more perspicacious lawyers that improved efficiency leads to an improved bottom line.

The key point is that AI needs to be trained by a human. It needs teaching to look for the right things in the right places first time and every time. AI understands neither where, why nor what it is looking for. Nor indeed why the material it seeks is either relevant or valuable. All AI can do is identify patterns of data. The template for those patterns has to be supplied by humans.

Orwell’s 1984 or Huxley’s Brave New World dystopian prophecy it certainly isn’t. However, AI will eventually change the legal landscape for you. To what extent will be determined very much by how willing you are to embrace the change.

Our clients range from small start-up legal practices to multi-partner, multi-site firms.

Another great customer service experience from LawWare. My laptop had to be stripped back to factory settings as part of a repair - taking hours! In contrast, restoring LawWare took one phone call to the support team and I was up and running in 6 minutes. If only everything was so easy!

As the first commercial user of LawWare back in 1998, we have had no hesitation in remaining with the product through its development. We thoroughly recommend it to any firm looking for a practice management system.

The helpdesk is exceptionally good. Whatever the query there is always a human being there to help. No leaving messages or being advised to go to a website. The best computer service for solicitors I have ever used!

The linking of documents and casefiles saves so much time! I have experience of several accounts packages and I like that LawWare is simple to use and easy to learn. Support is quick and effective and staff are helpful and courteous.

I have worked with a number of Case Management providers over the years but have not come across anything with the attention to detail and thoroughness of LawWare. My colleagues and I have not been disappointed.

Brymer legal Ltd.

I can’t imagine trying to be a law firm in the 21st Century without 21st Century IT systems. Having a ‘single system’ that underpins all the work, whether we are in the office or out, is an integral part of what we are building.

The level of support is the main benefit using this system.  The system itself once you have had training is simple and easy to use. We have a great relationship with LawWare and the ongoing support is second to none.

Significant preparation was required to configure and import the data from our old firm. We had to get all clients onto the new system and then learn how to use it. We just find it very easy to use, much easier than our old system.

Being a busy litigator with a growing firm it is incredibly useful to be able to view my files from any location with some form of internet connection. I am a fan, and want to keep working with LawWare to make a good product great.

The switch to the new LawCloud system, which is still on-going, has gone very well. We found the LawWare team without exception to be very helpful and knowledgeable. All queries are followed up and dealt with promptly.
