A more thorough explanation:

Attempted marriage is a type of marriage that is invalid from the beginning and cannot be made valid. It can be terminated by either party without obtaining a divorce or annulment. For example, a marriage is void if the parties are too closely related or if either party is already married. A void marriage does not exist, has never existed, and needs no formal act to be dissolved, although a judicial declaration may be obtained.

Example: John and Jane, who are siblings, attempted to get married. However, their marriage is void because they are too closely related. They do not need to obtain a divorce or annulment to end their marriage because it never existed in the first place.

Example: Mary is already married to Tom, but she attempts to marry Jack. Their marriage is void because Mary is already married to Tom. They do not need to obtain a divorce or annulment to end their marriage because it never existed in the first place.
