In the United States, whether you can sue the woman involved in your husband’s affair for emotional distress depends heavily on the state where you reside:
-
Most states DO NOT allow lawsuits against a spouse’s affair partner (“alienation of affection” or “criminal conversation”). Only a handful of states—primarily North Carolina, and to a limited extent a few others (Mississippi, South Dakota, Utah, New Mexico, and Hawaii)—still permit “alienation of affection” lawsuits against third parties for breaking up a marriage. In other states, such suits have been abolished.
-
Intentional Infliction of Emotional Distress (IIED): Lawsuits for intentional infliction of emotional distress against the affair partner are extremely difficult to succeed in. You would need to prove conduct far more “extreme and outrageous” than participation in an affair itself—such as public shaming, harassment, or threats—along with direct causation of “severe emotional harm” and documented damages like medical or therapy costs.
-
Photos or Instagram posts alone, or evidence of the affair, are usually NOT enough to meet the legal threshold for such claims in most places, unless the third party’s conduct was maliciously aimed at causing you harm, and was truly extreme by societal standards.
-
In most places, your remedies are focused on divorce proceedings: infidelity can sometimes influence issues like alimony or property division, but will rarely support a successful emotional distress lawsuit against the other woman.
-
If you are in North Carolina or one of the few states permitting these suits, consult a local family law attorney—these cases are rare and require specific proof.
-
In most other states, focus on divorce and, if applicable, gathering evidence that may help your case for financial settlements instead.
-
If it can be proved through hotel entries or similar documentary evidence that your husband and the other woman stayed together, this constitutes valid and strong grounds for divorce in India under the ground of adultery. Such evidence—hotel bills, register entries, or travel records—can help establish an extra-marital affair even if there is no direct admission.
-
Moreover, Indian law allows the aggrieved spouse to join the alleged paramour (the other woman) as a proforma party or co-respondent in the divorce proceedings. While the divorce itself proceeds between the spouses, making the paramour a party enables the court to summon her as a witness and record her evidence if necessary for proving adultery. This strengthens your case and allows the court to directly consider her role in the breakdown of the marriage.
