Question

What will happen if ravan marry sita?

Answer 1

Then Rama, after saving her, could not have taken her back as his wife and queen.

As it was, Rama banished Sita to the forest because the subjects of Ayodhya suspected Sita of being unpure. Then if you rememeber, Sita proved her purity during the Agni-Bhoomi scene in front of Rama and Ayodhya.

But...Ravan could never marry Sita. He was cursed by Kubera's son, that if he ever forced himself upon a woman against her will, all ten of his heads would fall off. This protected Sita. (Ravana tried to molest Kubera's son's fiance, the apsara Rhamba, so Kubera's son was angered)

Answer 2

They will get a divorce in less then 5 years.
