Can a non-Saudi brother transfer ownership of a house to his Saudi sister, based on a written acknowledgment from the Saudi brother, should the latter refuse to relinquish the house?

The fictitious registration of property ownership to defraud the system does not transfer ownership from the original owner. Therefore, the original owner has the right to dispose of it through buying and selling, while it is prohibited to violate the system established by the ruler for the public good. Based on this, there is no religious impediment to the non-Saudi brother transferring ownership of the house, which was fictitiously registered in his brother's name, to his sister.
