Question: We have learned that gentiles cannot marry through money, but do they have the concept of divorce?

Answer (R. Yudan ben Pazi and R. Chanin citing R. Chuna the great of Tziporin): Either they have no written divorce (as it is done verbally) or they must divorce each other (meaning that if either spouse wishes to divorce, they may do so).

R. Yochanan of Tzipurin/R. Acha/ R. Chinana citing R. Shmuel bar Nachman: The pasuk states (Malachi 2, 16), "...for one who hates (his wife) should divorce (her), says Hash-m, G-d of Israel'' - I gave divorce only to the Jews but not to the gentiles.

R. Chananya citing R. Pinchas: The rest of that portion describes Hash-m as 'Hashem of Hosts'; here He is referred to as 'G-d of Israel'. This teaches us that Hash-m only applied His name to divorce between Jews.

We can prove from R. Chiya the Great that gentiles do not have divorce...

Braisa (R. Chiya): If a gentile divorced his wife and she went and married another man and he divorced her and she then converted, about these people I do not apply the prohibition, (Devarim 24, 4) "the first husband who sent her away may not remarry her''.

Support (Braisa): Such a case came before Rebbi and he ruled that they may remarry each other.
