Does a spouse automatically get POA for health decisions and marriage?

Question Details:

My husband had a durable POA with his mother having control of any emergency health care decisions before we were married. We have now been married for 7 years. His mom just died and now he wants another one written up. Don't I automatically have the right to make those decisions since we are married? With the POA he had was his mother the one that would have made those decisions instead of me? If he makes a new one and I am not the person he names, what are my rights? I do not understand because I thought that since we are married, I had that right automatically. Important Notice
