2. Breaking social norms.
3. Unlawful.

Usage notes

Licit and valid are legal terms to be compared, especially in terms of canon law. With bigamy, if there is an innocent party, the innocent party is validly married; the problem is with the guilty party, who has entered into an illegal second marriage. The marriage is valid in canon law (and often, civil law), but the guilty party goes to jail nonetheless, in that the marriage is illicit (and illegal), and the innocent party routinely receives a fast annulment and the full sympathy of the court. A corollary is that the children born of such unions are inherently legitimate.

Not to be confused with elicit.
