Our standard answer is "no," although there may be exceptions if you and your ex-spouse remain very close friends. If your second marriage comes after the death of your first, for instance, we think it's extremely kind of you to invite the departed spouse's family. It's important to understand that they may not be able to make it due to the difficulty of the circumstance. The length of time since your divorce and the quality of your relationship with your ex-spouse are both important factors. The majority of married couples, we believe, would answer this question negatively.
