What is the name of your state? California

My step father got divorced from his first wife and got the entire property in the divorce settlement. He had married my mother and has passed away several years latter, he had left the property to my mother in his will.
Now the ex-wife_s name was never taken off the deed after the divorce.
I had contacted her and asked, would you sign a quick deed over to my mother to release her interest in the property. She refuses to so, she stated she never singed a quick deed after the divorce, and she was going to be entering the property in to her living trust, and she stated she was also looking in to selling the property.
I had sent her a letter to her along with a copy of the divorce settlement, in hopes she would do the right thing. I have not received a response as of yet.
My mother has copies of the divorce settlement, and the will.
The deed on record shows that my mother and the ex-wife hold equal shares in the property, when the ex-wife should have none.
What dose my mother need to do to get the ex-wife off the property deed? And stop any pending sale?

you need to refer to your other thread for those answers. You also need to refrain from starting multiple threads on the exact same subject. It gets confusing when you atart referencing onther threads.
