Should You Tell the Other Spouse About Your Partner's Affair During Divorce?

Does Adultery Affect Divorce Outcomes?

Adultery remains legal grounds for fault-based divorce in 27 states. In states like New York (N.Y. Dom. Rel. Law § 170(4)), Virginia (Va. Code § 20-91(A)(1)), and Texas (Tex. Fam. Code § 6.003), proving adultery can influence alimony awards and property division. According to the American Academy of Matrimonial Lawyers, approximately 62% of divorce attorneys report that adultery affects spousal support outcomes in fault states.

However, in pure no-fault divorce states like California and Florida, infidelity generally has no bearing on financial outcomes — though it may still factor into custody decisions if the affair exposed children to inappropriate situations.

Should You Tell the Other Betrayed Spouse?

This is ultimately a personal and ethical decision, but there are important legal considerations to weigh first:

Consult your attorney before disclosing. A family law attorney can advise whether sharing this information could help or hurt your case. In some situations, premature disclosure can:

• Alert your spouse that you're gathering evidence, prompting them to destroy records
• Create conflict that escalates custody disputes
• Be perceived by a judge as vindictive rather than protective

Preserve your evidence first. If you have location data, transaction records, or DNA evidence, secure copies with your attorney before confronting anyone. According to a 2024 survey by the American Bar Association, 73% of family law attorneys recommend clients document evidence of infidelity before taking any action — even in no-fault states — because circumstances can change during proceedings.

How Does This Affect Children and Shared Social Circles?

Research from the Journal of Family Psychology shows that children in high-conflict divorces experience 2-3x higher rates of anxiety and behavioral issues compared to amicable separations. When mutual friends and school communities are involved, managing disclosure carefully becomes even more critical.

Practical steps to consider:

• Set boundaries first. You can limit contact with the other family without full public disclosure. Request schedule changes for shared activities through your attorney if needed.
• Prioritize your children's stability. Avoid situations where children witness confrontations or learn details about the affair from adults other than their parents.
• Consider timing. Many therapists and attorneys recommend waiting until you have a clear legal strategy before involving additional parties.

What About Using Adultery Evidence in Court?

If you pursue a fault-based divorce, evidence of adultery must typically meet specific standards. In Virginia, for example, adultery must be proven by "clear and convincing evidence" — a higher bar than most civil claims. Hotel records, financial transactions, and communication logs can all serve as evidence, but a qualified family law attorney can help you understand what your jurisdiction requires.

What Steps Should You Take Right Now?

1. Retain a family law attorney before making any disclosures
2. Secure all evidence — screenshots, location data, financial records
3. Begin individual therapy to process the emotional impact
4. Avoid posting on social media about the situation
5. Review your state's laws on fault divorce through our divorce questions hub to understand whether adultery impacts outcomes in your jurisdiction

The decision to tell the other spouse is deeply personal, but making it from a position of legal preparedness — rather than emotional reaction — protects both you and your children. Laws vary significantly by state, so what matters in a Texas divorce may be irrelevant in California. A local attorney can provide jurisdiction-specific guidance tailored to your circumstances.
