Annulment is a legal procedure for declaring a marriage null and void. Unlike divorce, it is retroactive: an annulled marriage is considered never to have existed.
In strict legal terminology, annulment refers only to making a voidable marriage null; if the marriage is void ab initio, then it is automatically null, although a legal declaration of nullity is required to establish this. The process of obtaining such a declaration is similar to the annulment process. Generally speaking, annulment, despite its retrospective nature, still results in any children born being considered legitimate in the USA.
