Documenting cheating overseas is a term used to describe the necessary documentation that women and men may need to do to prove that their partner failed to be faithful to them while they were overseas. The other spouse may have been traveling for business or pleasure, or even for the military. In any instance, if the spouse wishes to use this cheating overseas as a tool in court to file for divorce and to receive alimony, he or she needs to have proof that the event actually occurred. Due to the logistics, this can be difficult to do.
