Both of these agreements can be enforced with valid evidence to back it up in case of any allegations held. However the main difference between these types of agreements is the chance of an individual not sticking to their word in a verbal agreement. Verbal agreements can be just as valid as a written argument, as long as there is evidence to prove it; e.g. a voice recording. However, a written agreement has no chance of being edited and can be seen by all the employees involved, making this a easier technique when forming contract agreements.
