If a couple ever gets divorced they need to change more than just a relationship status. Durable Power of Attorney and Healthcare Power of Attorneys are not changed automatically with a divorce. Each party of the divorce needs to redo these documents to indicate that you no longer want this person to make medical decisions for you or be your representative if something happens to you. If you get a divorce, review all of your legal documents and address the ones that need to be changed.
Depending on how your Will was written you may also need to adjust that too. Some state have that a will automatically changes upon divorce, but double check with your lawyer.
