What Happens to Trust Assets When Successor Trustee and Beneficiary Dies?

My aunt is Successor Trustee of my deceased grandmother's estate. My grandmother has a revocable trust and everything is supposed to be divided between my aunt and my mother. Well, my aunt just passed away a week ago. So does this mean that everything now belongs to my mother?

What if my aunt is married and her husband is not mentioned in the revocable trust? Is he entitled to anything?

I would appreciate any feedback on this issue....Thank you.
