The ruling on referring a dispute over shared land to the judge

Question:
Muhammad Lahir al-Zahrani from Riyadh says: My full brother, who is well-off, and I, who am poor and in need of Allah, he asked me one day to survey a piece of land we own so that we could build two houses on it, one for me and one for him. Because I could not afford the costs of construction, I agreed with him. I worked on his house until it was nearly finished, then I asked him to start building my house according to the agreement, but he refused and dismissed the agreement between us. Yes, knowing that I participated in building his house with my labor, while he provided the money and the land on which the house is to be built belongs to our father, whom he inherited from his father. Do I have the right to demand half of the house, or not? And does our father have the right to give him a legal deed to the land, after he has learned what happened between us, or should I make him take an oath that there was no agreement between us? Knowing that it was only a verbal agreement, and there is nothing to prove it in writing or with witnesses?

Answer:
This is a case with two parties, or rather three parties: you, your brother, and the father. There is a dispute, so it must be referred to the judge. You must bring the case to the judge, and the judge will take charge
