I am eighty-six years old, and I have nine children. I own several properties, and my eldest son is sixty-two years old. I built a house for him, secured him a marital life from my wealth, and bought him a taxi. However, my son has become disobedient to me and has filed many lawsuits in court to inherit from me while I am still alive. He does not hesitate to insult me with the worst words. Am I entitled to deny him inheritance?
