Family law attorneys are all too familiar with the common refrain: "My spouse [or ex-spouse] is harassing/stalking me." While most matrimonial attorneys know the elements of those crimes – N.J.S.A. 2C:33-4 (harassment) and N.J.S.A. 2C:12-10 (stalking) – and, of course, the differences between colloquial parlance and the statutes, things get stickier when our clients are themselves accused of harassment or stalking. The situation can become even more complicated when a client seeks to investigate their spouse (or have that spouse investigated by a third party) using real-time tracking methods such as GPS.
