Mr. A, a businessman, put several real estate properties under the name of his eldest son X because at that time, X was the only one of legal age among his four children. He told his son he was to hold those assets for his siblings until they become adults themselves. X then got married. After 5 years, Mr. A asked X to transfer the titles over three properties to his three siblings, leaving two properties for himself. To A's surprise, X said that he can no longer be made to transfer the properties to his siblings because more than 5 years have passed since the titles were registered in his name. Do you agree?
