It's never easy to co-parent with a former spouse, because no matter how amicable the divorce process was, it is bound to have created a rift between the two of you. If you have decided to co-parent, this is great news. It means that you have both committed to putting the past behind you and only want the best for your child or children.
If you are divorcing your spouse amicably, it is ideal if you can mutually decide on as many decisions as possible together. This can range from the dividing of the house and other assets, to child visitation, support and alimony. The more that you can decide together, the better coparents you will be and there will be less chance of resentment in your relationship.
