Adultery in the military is prosecuted as extramarital sexual conduct under Article 134 of the Uniform Code of Military Justice. A recurring question is whether a service member can be punished for attempting that offense when the planned encounter was interrupted, called off, or never reached the point of any sexual contact. The answer is that attempted extramarital sexual conduct can be charged by combining Article 80, the attempt statute, with the Article 134 offense, but the prosecution faces real proof hurdles, and the absence of completed contact significantly affects what the government must show.
The Underlying Offense Under Article 134
Extramarital sexual conduct under Article 134 has three elements. The accused wrongfully engaged in defined extramarital sexual conduct with a certain person; at the time, the accused knew that the accused or the other person was married to someone else; and under the circumstances, the conduct was prejudicial to good order and discipline, was of a nature to bring discredit upon the armed forces, or both. The conduct itself is defined by specific sexual acts. Critically, the completed offense requires that one of those acts actually take place. If no qualifying sexual act occurs, the completed Article 134 offense is not made out.
That is exactly why the attempt theory matters. When the act never happened, the government cannot prove the completed crime, so it must instead prove that the accused tried to commit it.
How Article 80 Supplies the Attempt Theory
Article 80 punishes an act done with specific intent to commit an offense under the code that amounts to more than mere preparation and that tends, even if it fails, to bring about the offense. Applied to extramarital sexual conduct, the government must prove that the accused specifically intended to engage in the defined extramarital sexual conduct, knowing of the marriage; that the accused committed an overt act toward that end; and that the act went beyond mere preparation, amounting to a substantial step toward completing the offense. Because attempt borrows the underlying offense, the terminal element, prejudice to good order and discipline or service discredit, remains part of the analysis.
So yes, attempted adultery is punishable, charged as an Article 80 attempt to commit the Article 134 offense, even when no sexual contact ever occurred. The conviction does not require completion; it requires intent plus a substantial step.
The Preparation-Versus-Attempt Line Is the Battleground
The decisive issue is whether the accused’s conduct crossed from preparation into a substantial step. Arranging to meet, expressing desire, exchanging messages, or making plans can often be characterized as preparation, which is not enough. Conduct that puts the plan into motion, such as traveling to a private location for the agreed encounter or taking concrete steps that strongly corroborate the intent to engage in the sexual act, is more likely to qualify. Because there was no contact, the entire case rests on this line, and the defense frequently argues that the accused never progressed past planning, or that the intent was conditional, abandoned, or never firm.
Knowledge of Marriage and the Wrongfulness Requirement
The accused must have known that someone in the relationship was married. The conduct must also be wrongful, and military law recognizes defenses tied to marital status. A legal separation by court order can serve as an affirmative defense, and a mistake of fact, an honest and reasonable belief that both parties were unmarried or legally separated, can negate the offense, with the government bearing the burden to show the belief was unreasonable or dishonest once the defense is raised. The status of a pending divorce is more ambiguous; ongoing divorce proceedings may not be a complete defense, but they can affect how wrongfulness is assessed. These defenses apply to the attempt charge as well, because the accused must have intended the wrongful conduct.
Service Discredit and Good Order Even Without Contact
Some assume that without contact there can be no harm to good order and discipline. That is not the rule. The terminal element looks at the nature and circumstances of the conduct the accused intended and the steps taken, and conduct can be prejudicial or discrediting based on the surrounding facts. At the same time, this element gives the defense another avenue, since an interrupted, private, and unknown attempt may be harder to characterize as prejudicial or discrediting than an open and notorious affair.
Why Charges May Be Reframed or Declined
Because attempted extramarital sexual conduct is fact-intensive and the harm element is contestable when nothing happened, commands often handle such allegations through nonjudicial punishment, administrative action, or a related but distinct charge rather than a contested attempt prosecution. Whether to pursue the attempt is a discretionary call influenced by the strength of the evidence on intent and substantial step.
Practical Takeaways
Attempted adultery is punishable in the military by charging an Article 80 attempt to commit Article 134 extramarital sexual conduct, and a completed sexual act is not required. The government must prove a specific intent to commit the defined conduct, knowledge of the marriage, an overt act amounting to a substantial step beyond mere preparation, and the terminal element. The lack of contact concentrates the dispute on whether the conduct ever left the preparation stage and on the marital-status and mistake-of-fact defenses. Anyone facing such an allegation should consult military defense counsel promptly, since early statements about intent can be the difference between mere preparation and a chargeable attempt.
