Distributing the land in inheritance when one heir built a structure on it
Q: I built on my mother's property with her permission, my sibling doesn't want to compensate me for the improvements. She say that I occupied it for free for many years.
My Mother is late. I have one sibling (sister) we and are heirs to the property.
What is the Islamic ruling on this? Does she have a claim on the building that I erected with my funds and the proceeds that come from it or does she have a claim only for the land that the building was erected on?
