Learning that you are under investigation or have been accused of adultery under the Uniform Code of Military Justice is unsettling, and the decisions made in the first hours and days often shape everything that follows. The offense, now titled “Extramarital sexual conduct” at Part IV, paragraph 99 of the current Manual for Courts-Martial, is charged under Article 134, codified at 10 U.S.C. section 934. This article lays out the practical steps a service member should consider when facing such an accusation. It is general guidance rather than legal advice, and the single most important step is to obtain counsel from a qualified military defense attorney as early as possible.
Step One: Exercise Your Right to Remain Silent
Before anything else, understand and use your rights. Article 31 of the UCMJ requires that you be advised of the nature of the accusation and of your right to remain silent before you are questioned as a suspect. You are not obligated to explain yourself, and statements made in the moment, even ones intended to minimize or clarify the situation, can be used against you. The safest course is to politely decline to answer questions about the allegation and to state that you wish to speak with an attorney. This is true whether you are approached by law enforcement, a commander, or an investigator.
Step Two: Do Not Discuss the Case Casually
It is natural to want to talk through a crisis with friends, family, or unit members, but conversations about the facts can create witnesses against you and can complicate your defense. Anyone you confide in may later be interviewed. Limit discussion of the substance of the allegation to your attorney, with whom communications are privileged. Be especially careful with text messages, emails, and social media, all of which can be collected as evidence.
Step Three: Preserve Evidence and Avoid Destroying Anything
Do not delete messages, photographs, or other records, and do not encourage anyone else to do so. Destroying potential evidence can itself lead to additional charges such as obstruction and can severely damage your credibility. Instead, preserve documents that may help your defense. Records that show the legal status of your marriage, such as a court order of legal separation or a divorce decree, can be critical given the defenses available for this offense. Keep them safe and provide them to your attorney rather than acting on them yourself.
Step Four: Retain a Qualified Military Defense Attorney
You are entitled to free representation by a military defense counsel, and you may also retain a civilian attorney who concentrates on military justice. Either way, secure representation quickly. Counsel can communicate with investigators and the command on your behalf, ensure your rights are protected, and begin shaping the defense from the outset. The earlier an attorney is involved, the more options remain available, including the possibility of resolving the matter before charges are ever formally preferred.
Step Five: Understand the Elements and Your Possible Defenses
Work with your attorney to understand what the government must prove. It must establish that you wrongfully engaged in extramarital conduct with a certain person, that you or the other person was married to someone else at the time, and that under the circumstances the conduct was prejudicial to good order and discipline, service discrediting, or both. Each element is a potential defense. The current Manual recognizes a defense of legal separation, recognizes that the conduct is not punishable if the parties were unmarried or legally separated, and preserves a mistake of fact defense for an honest and reasonable belief about marital status. Your attorney can also challenge whether the conduct caused any genuine military harm, applying the factors listed at paragraph 99.c.
Step Six: Cooperate With Your Attorney, Not With the Investigation
Cooperating with your defense team is not the same as cooperating with the investigation. Provide your attorney with a full and honest account of the facts so that counsel can advise you accurately and is not surprised later. At the same time, do not volunteer statements to investigators or sign anything without your attorney’s review. Let your counsel decide what, if anything, should be communicated to the government.
Step Seven: Continue Performing Your Duties Professionally
While the case is pending, maintain your military bearing and continue to perform your duties to standard. Your conduct during the investigation can influence how the command views you and can become relevant to disposition decisions and to any later administrative or clearance proceedings. Avoid contact or conduct that could be seen as retaliation, intimidation of witnesses, or further misconduct.
Step Eight: Prepare for Collateral Consequences
An adultery allegation can reach beyond the criminal forum into administrative separation, nonjudicial punishment under Article 15, adverse evaluations, reprimands, and security clearance review under the national adjudicative guidelines. Discuss these possibilities with your attorney from the start so that the criminal and administrative tracks are handled in a coordinated way. Decisions made in the criminal matter can affect the clearance and administrative outcomes, and vice versa.
The Bottom Line
If you are accused of adultery under the UCMJ, stay silent about the facts, preserve rather than destroy evidence, avoid casual discussion of the case, and retain a qualified military defense attorney immediately. The defenses available for this offense, including legal separation and mistake of fact, and the requirement that the government prove a real military nexus, give a well prepared defendant meaningful avenues to contest the charge or to resolve it favorably. Acting deliberately and with experienced counsel from the outset gives you the best chance to protect your liberty, your career, and your future.

Military law also changes over time. The Military Justice Act of 2016 (effective January 1, 2019) and subsequent National Defense Authorization Acts renumbered and rewrote many punitive articles, revised the Article 32 preliminary hearing, and altered sentencing, clemency, and appellate procedures. Statutes, regulations, executive orders, the Manual for Courts-Martial, and decisions of the service Courts of Criminal Appeals and the Court of Appeals for the Armed Forces may have been amended, superseded, or reinterpreted after this article was written, and article numbers or procedures cited here may have changed.
