Is it permissible to divide a gas station and the facilities built upon it by means of witnesses, and what is the share of the partner who contributed to its establishment, but whose contribution was not mentioned in the deed of gift? Does he have the right to claim it or its value in case of dispute?

If the father and the paternal uncle collaborated on building a station, and the uncle gifted the father half of the land, then the father's share in the project remains and the uncle is not permitted to seize it, even if the properties are registered in the uncle's name. A judge's ruling does not make the unlawful lawful, and whoever is granted something belonging to his brother through a judgment, verily, a piece of fire is cut off for him.
