The signed agreement is valid, and your mother has the right to dispose of the house. But you have no direct inheritance. If you want to inherit from generation to generation, you must get the consent of the legal heirs of grandma's three daughters, so the procedures and problems are more complicated.

It is suggested to re-register the ownership and go through the formalities of property inheritance first, and then go through the formalities of property donation in the name of your mother as the owner of the property and trade it in your name.

1. I don't know what agreement you signed, but you must notarize the inheritance. Your mother inherits all the shares of the real estate, and your second aunt can apply for giving up.
