Later this week I'm running a session for a group of leading technology lawyers which will explore the future of the profession.

Why I think this will be a particularly interesting topic for this group is that I believe technology will be the single biggest driver of change for the legal sector in the long term.

Sure, globalisation, outsourcing, commoditisation, changing procurement patterns are all shaping the market now, but technology has the potential to change it to a much greater degree. Here's why.

There are a number of technology trends that have already influenced the profession to a greater or lesser degree:

• The internet has enhanced communication speed and accessibility, which has fundamentally changed client service expectations and the response times in the market;

• The vast amount of electronic information available has made search and retrieval a vastly different affair to that of twenty years ago, when a trip to the law library and a long afternoon was required to get oven an overview of the latest law in an area;

• Collaboration software is allowing the process of working with internal stakeholders and external parties to become more efficient (not least by reducing the number of times documents are passed backwards and forwards);

• The sharing of information between law firm clients has become far more widespread (intensified by social media) so that emerging client buying patterns such as the rejection of hourly billing become more adopted more quickly;

• Technology supports the standardisation of work, with more and more firms focussing on efficiency and improving process, tools like workflow software can support and enhance changes to the way lawyers work;

• The automation of low complexity work, most visible in the consumer space (think automated wills online), is also beginning to see wider adoption in the B2B space as more complex work gets disaggregated and the low complexity components get packaged up and automated (standard due diligence report anyone?).

However, to my mind, this is really only playing on the edges of what's possible. Where I'm really interested is the area of law where lawyers believe they add most value. The high-end, complex work. The work that NEEDS a specialist. A true expert.

Lets go right to the "business end" of the legal value chain. Think about the legal sector and what it actually does.

Law is made (the government legislates, courts decide a case etc). This law is recorded and at a high level interpreted (often by academics and other commentators). The combination of these two steps provides a shared view of generally what the law is.

By and large, and the moment the value here is really only accessible to legal practitioners – the public  can get access to certain statutes and cases for free online, but the public's ability to understand what they mean remains limited – although this is beginning to change.

The next step is to turn this information into a broad set of tools (largely documents – agreements, policies and other commercial instruments) and for the lawyer to use these tools and his or her understanding of the law to interpret the high level meaning and apply it to a particular set of facts, and in doing so create some further value for which the client will pay.

Somewhat simplistic, but in very basic terms, the majority of the value that the market will pay for is in this interpretation and application of the law to increasingly complex situations. There are other factors that drive value such as the scale and risk involved, but generally speaking, more complex work means higher fees.

Looking a bit more closely at what lawyers actually do in this high value phase, in the vast majority of cases it will take two forms – advising and creating documents. We already know that technology is starting to shape document creation (have a look at Epoq, Rocket Lawyer, LegalZoom and LexisNexis if you don't believe me), but surely (SURELY) technology couldn't actually start to creep into advising clients? Could it?

This is the skill honed over years of hard-earned experience. The ability to steeple fingers, sit back in chair and let the cogs turn. To casually drop a Latin phrase into an argument. Those uniquely human abilities to find meaning and similarities between cases and facts. To both synthesise, analyse and structure highly complex information.

The skill that requires (in the UK) a three-year law degree, a year of practical training, a two year stint of on-the job training, before the brightest and best graduates can call themselves qualified and enter the profession fully to "start" their career and their real learning.

Surely not.

"Trading floors were once the preserve of adrenalin-fuelled dealers aggressively executing the orders of brokers who relied on research, experience and gut instinct to decide where best to invest.

Long ago computers made dealers redundant, yet brokers and their ilk have remained the masters of the investment universe, free to buy and sell wherever they see fit.

But the last bastion of the old order is now under threat.

Investment decisions are no longer being made by financiers, but increasingly by PhD mathematicians and the immensely complex computer programs they devise."

While there are many differences between this activity and the legal profession, there are also plenty of similarities.

Once you start really looking at what lawyers do, and begin to grasp what technology is already capable of, a real threat to the profession as we know it doesn't seem so far fetched.

Entity recognition (understanding, finding and cross-referencing individuals and organisations in documents) is already well established, and software like Autonomy ("the leader in meaning-based computing") can do magical things in terms of identifying relationships between "things" and deriving meaning from raw information (think "facts").

Look at recent developments in ediscovery and contract management software, and have a read of Jason Wilson's great post on lawyers, I am now an app, and of course, whether you agree with him or not, do revisit Richard Susskind's work.

For me, rather than the commentary in the area, what makes me really believe big change is coming, is what I hear and see when I talk to some of the leading technology thinkers in this area.

To hear them describe the law by talking about decision trees and statistical probability (based on historic data and future trends), to hear them explaining rules engines, logic and information structures, really makes me pause for thought.

It's a different language, but with the same objective of solving problems and creating value for clients.

This type of technology promises a paradigm shift in speed, accuracy and cost reduction that goes far beyond what an LPO could offer with a human based process.

Of course it's not that simple. Apart from the very real time, effort and money required to build the technology, aside from the judgment required to apply the law, there is of course a truly human element in providing legal service (that word is a clue). This service wrapper is likely to keep large chunks of the profession safe for a while, and of course as one work type is automated, the opportunity for the profession is to find a new, higher value area of law to explore.

My (human!) instinct is that it will be lawyers who first use these new generation of tools first, to provide faster, better services to their clients, rather than clients using them directly to replace lawyers.

The lawyers may be at traditional law firms (large or smaller niche players) or LPO or other volume providers. Either way the early adopters will become the Terminators, the firms that resist will be Sarah Connor.

Seems far fetched? My belief is that the fundamental changes now facing the profession are only the beginning of the beginning, and that technology will shape the end game far more than any of us can probably predict.
