Single Adultery Law and Legal Definition

Adultery is a voluntary sexual intercourse between a married person and another person who is not the offender’s spouse. Single adultery is an adultery in which only one party is a married person. It is different from a double adultery in which both the parties involved in the adultery are married to other persons.

The following is an example of a case law referring to the term:

Adultery is the sin of incontinence between two married persons, or if but one of the persons be married, it is nevertheless adultery; but in this case it is called single adultery to distinguish it from the other, which is double. [HUNTER v. UNITED STATES, 1 Pin. 91 (Wis. 1840)].
