If you and your spouse think you can agree to your own terms with help from a neutral third party, mediation should be considered. The mediator will help you to explore options through each step of the mediation process.
Like mediation, collaborative divorce is a cooperative method of negotiation. However, each spouse has an attorney representing them as well as selecting other neutral professionals. The collaborative team uses cooperative, rather than combative, negotiation techniques.
I encourage my clients to think of premarital agreements, not as an assumption of an impending divorce, but as an opportunity to openly communicate about their finances and expectations.
