A fаther оwned а piece оf prоperty locаted near the state university. His son was a student at the university, and the father allowed the son and the son’s classmate to live in the large house on the property rent free. On the son’s 20th birthday, the father handed the son a signed instrument of conveyance containing the following language: “I give the property to my dearly beloved son on the condition precedent that he receive a college degree before he reaches the age of 30, and if he does not receive the degree by his 30th birthday, to my beloved daughter.” The son promptly recorded the deed. Shortly thereafter, the son asked his classmate to start paying him rent. An argument evolved out of the son’s request and the son told the classmate to get off his property. The classmate refused to leave and the son filed suit to evict him. How will the court rule?
