We are introducing a bargaining model that we call “Winning Negotiations based on Game Theory principles.” By way of introduction, our goals are simple: we want to introduce a model of negotiation that is quite different from the typical adversarial model often used. Our model would apply to many legal situations. However, but our background is in family law, and our model is particularly applicable to that strife- burdened process of divorce. I or in some cases, it is also applicable to parental separations in which the parties have never been married. Attorneys who have been practicing for a long time, because of training and experience, are less likely to shift in their negotiation model. However, and we are convinced that the way to change the manner in which family law is conducted is for new lawyers entering practice to enter with a different mindset and a new set of bargaining skills.
