Should Fitbit Data be Used in Family Court?

These days there is no shortage of technology that quite literally tracks our every move: In the area of health and fitness, for example, there are Fitbit wristbands and similar devices which can monitor everything from the number of steps taken or stairs climbed in a day by the wearer, as well as his or her sleep patterns.

What if one day all that data gets trotted out (pun intended) before a Family Court judge in a divorce case?

About two years ago an Alberta personal injury lawyer made headlines because he intended to use the data obtained from a Fitbit to prove that his client, a personal trainer, had been in “peak physical shape” before allegedly suffering physical injuries in an automobile collision. This was apparently the first time in Canada that the information from such devices had been proposed for use as evidence in court.

Although the correlation is somewhat more direct in the scenario of a personal injury action, theoretically the data obtained from such fitness trackers could be used in Family Law cases as well: for example to bolster a spouse’s argument that he or she is legitimately depressed and inactive post-divorce. This in turn could play into the assessment of the spouse’s current ability to work – and by extension, of his or her “need” and legal entitlement to spousal support.

Of course this amounts to a double-edged sword: it’s one thing to voluntarily offer up your personal tracker device as evidence, but another thing entirely to have it (figuratively) wrestled from you and used against you in litigation. And of course, as with any sort of evidence of this nature there is opportunity for the wearer/user to manipulate the data, not to mention debate over potential frailties in data analysis methods, the limits of conjecture, and the validity of the resulting conclusions.

But it all raises the important legal policy question of such highly-personal and private information should be considered relevant and made compellable – by a court if necessary – as part of the discovery process that is a key part of the Canadian justice system.

So the next time you put on that Fitbit, or enter your day’s calorie intake in an App, or post your morning run statistics on Facebook, give some thought to how and whether this information could theoretically be used against you in the future.
