Effects of marriage is a legal term of art used to describe all of the rights and obligations that individuals may be subject and entitled to if they are in a common-law marriage, an annulled marriage, domestic partnership or a civil union.

Thus, even if the underlying marriage is held to be void there may still be rights and obligations that continue and are recognized by court order. An example may be an annulled marriage where the court awards alimony to the weaker, poorer or less well educated spouse to allow him or her a period of time to go back to school or re-enter the work force.
