Guilt is an emotion commonly experienced in divorce. Although guilt has been shown to increase cooperative negotiation behavior in organizational contexts, this is the first investigation of the role of guilt in divorce negotiations. Using survey data of 457 divorcing individuals, the authors examined how guilt was related to the most relevant negotiation styles, while controlling for the guilt-overlapping emotions shame and regret. Guilt was related to cooperative negotiation behavior (i.e., more yielding and problem-solving behavior, and less forcing behavior). Shame was related to uncooperative negotiation behavior (i.e., more forcing, more avoiding, less problem-solving behavior), whereas regret had no additional explanatory value
