(1) Although "the name on the property certificate is Grandma", if this house was bought or built after your grandmother got married, then this house is still the property of husband and wife, and your grandmother's will only has half the right to dispose of this house.

(2) If your grandmother's will is also signed by your grandfather, it is agreed to be inherited by you: your grandfather wants to go back on his word now and can only make a notarized will and inherit half of his property to his son; If your grandfather doesn't make a notarized will, it is impossible for him to give his son the house he made with your grandmother before the change.

(3) If your grandmother's will doesn't have your grandfather's signature: No matter whether your mother gives up inheritance or not, as long as your grandfather makes another will and gives his half of the house to his son, you can only get your grandmother's half of the house.

(4) However, if this house was jointly owned by your grandmother and your grandfather before remarriage (this requires you to provide evidence, such as the time of registration in the house purchase contract or real estate license), this house is your grandmother's personal property before marriage, and your grandmother has a notarized will to tell you that your grandfather has no right to interfere. You just need to transfer the house to your name now, and the house is your property.

2. Stores:

(1) 10 years ago was registered in your mother's name, and now your grandfather wants it back. Unless your grandfather can produce evidence to prove that he didn't know when your grandmother was transferred to your mother for the first time, it is possible to take back the shop, give him half first, and the rest will be inherited by your grandfather, your mother and your uncle if your grandmother has no will.

(2) If the store existed before your grandmother remarried, your grandfather has no right to claim the division of the store. Even if he has evidence to prove that he doesn't know about the transfer to your mother, he has no right to return the store.

(3) Your grandfather didn't know that the store was for your mother even when he transferred the ownership 10 years ago: if he knew before the prosecution, and it has been more than two years since the prosecution, it is beyond the statute of limitations, and your mother can request the court to reject it.

Grandpa forced me and my mother to give up the inheritance right of the house and compensate us a little money. He wants to give the house to his son! I don't want to sign, now they want to sue my mother! " ：

(1) Ignore him and let him sue. People who have no evidence to sue him can't win.

(2) It is impossible to force you to give up your inheritance: your inheritance is inherited from your grandmother according to her will and has nothing to do with her. Even if the house is the same property of their husband and wife, even if your grandmother doesn't sign it for you in her will, you can get half of the house that belongs to your grandmother, and she has no right to interfere to make you give it up.

4. "But as far as the store is concerned, what are our chances of winning if we are sued?" Is it possible that they can't take the house and the shop? Or take it all! " :

(1) Store: If it was transferred 10 years ago, it is very likely that he could not prove that he was never informed, and it is also very likely that the statute of limitations has expired. It depends on what evidence your mother can find and what evidence your grandfather can provide.

(2) house: at least half of it can be obtained. If his signature is on the original notarized will, you are entitled to his half unless he makes another notarized will to change the original will.

(3) It is impossible to take them all away.

5. "I really hate my grandfather and have no conscience at all." Needless to say, it is your conscience to raise him. What he wants is his business.
