When people divorce, they are cancelling their legal duties and responsibilities of the marriage.

The laws governing divorce vary around the world.
yeah what is it when its like the marriage is cancled?
Annulment is when the marriage is declared null and void.

People get divorced for reasons such as sexual incompatibility or lack of independence.
