When should you consider using computer forensics?

If any form of digital information is even remotely involved in a case or legal situation, a computer forensic examination will be required. Digital information has invaded virtually every aspect of our day-to-day existence, having become a basic component of our lives, from computers, to smartphones, to social networking, digital information plays a crucial role in almost every case.

Computer forensics differs from data recovery, which is, recovery of data after an event affecting the physical data, such as a hard drive crash. Computer forensics goes much further. Computer forensics is a complete computer examination with intricate analysis of digital information being the ultimate goal.


For a successful forensics examination, you must have all the information relevant to a matter, not only to construct effective legal strategies, but also to focus your expectations and efficiently budget your services. There is nothing more difficult to address than a case which has become complicated by new facts, where you once expected the matter to proceed smoothly and without significant cost. Knowing all the facts early in a matter, allows you to better prepare for those cases that will require significant legal expertise to manage.

In response to pending litigation, analysing your relevant ESI is an excellent way to discharge your duties to preserve evidence and avoid spoliation, while also acquiring all relevant information essential to your legal theories and strategies. Similarly, as part of critical business decisions, forensically analysing relevant computers and devices can provide essential information. For example, analysing the computers of corporate officers or employees as part of the termination process can alert you to possible litigation issues such as violation of non-compete agreements, improper copying of intellectual property, etc.

To prepare for litigation, an attorney ought to determine whether a Request for Production of Documents will obtain all relevant evidence. A simple question to ask is whether you want to discover part of the relevant information (i.e. visible by your opponent’s operating system) or all of it (deleted, hidden, orphaned data, etc). It is not unrealistic to anticipate that information contained on a computer system which is helpful to a matter would be saved, while that which is harmful would be deleted, hidden, or rendered invisible. For example, in sexual harassment cases, it is not unusual to discover deleted emails and other data invisible to the operating system that significantly impacts the case. Computer forensic analysis extracts all the emails, memos, and other data that can be viewed with the operating system, as well as all invisible data. In many cases, the invisible data completely changes the nature of a claim or defense, often leading to early settlement and avoiding surprises during litigation.

In any situation in which one or more computers may have been used in an inappropriate manner, it is essential to call a forensic expert. Only a computer forensic analyst will be able to preserve, extract, and analyze the vital data that records the “tracks” left behind by inappropriate use. Taking the wrong steps in these circumstances can irrevocably destroy the vestiges of wrongful use that may result in litigation or criminal prosecution.

Be careful what you text!

Couples who may be heading toward a nasty break-up should always be extra careful when they send SMSs or WhatsApp messages. These messages could end up as evidence against them in divorce court!


In the past years, because of advances in digital forensics, there has been a huge spike in the number of cases using evidence from iPhones and other smartphones.

With emails, you can always think about what you’re writing and rewrite them. There is a windows of opportunity to rethink what you are saying, however with instant messaging, it is immediate. Many people send out messages without even thinking.

This is described as “spontaneous venting” and it can come back to haunt you! These instant messages can be recovered at a later stage to reveal your thoughts, actions and intentions.

SMSs, WhatsApp messages and other instant messages have been the most common form of divorce evidence taken from smartphones, followed by emails, phone numbers, call history, GPS and internet search histories.

Divorce lawyers advise their clients not to use Facebook to send messages or post inappropriate statuses, as it is the main source of divorce evidence from social media. However, only about half the couples actually follow their advice.

Anything that is in writing, you have to assume that someday a judge is going to see it. So, if it is not something that you don’t want a judge to see – don’t write it down!

You can always erase your messages, but that doesn’t mean they erase theirs.


With the latest tools and forensic software, the digital investigators at DLA are able to assist investigators and attorneys from their Cape Town offices on a national basis.

At DLA, it is possible to forensically acquire material from basic handsets to the latest smartphones, from all mobile and cell phone manufacturers using a range of advanced forensic and data recovery techniques.
