Taking the rights of orphans and disposing of them for himself

Question:
Peace be upon you. And upon you be peace. I want to thank you, may Allah prolong your life. Please go ahead. My wife has a residential plot, and they are her relatives. It belonged to their grandfather, their grandmother, and their father. After their grandfather passed away, they took possession of this land, which was their inheritance, and they did not give them any share of it. Then they sent for their grandfather—may Allah have mercy on him—to send a paper for them to sign. They did not know what they were signing, so they signed it and left. They built a house on it and made some renovations, but they did not give them any part of this land.

Answer:
My brother, this is a serious matter, O Shaykh. All right. I say that this is a problem you should take to the court. If, as you mentioned, he took the rights of the orphans and disposed of them for himself, this is injustice, and you should take it to the court. Yes.
