Reading your spouse’s email without permission is a federal crime, and in most states it’s a state crime as well. Marriage creates no exception. A first offense under the main federal statute can bring up to a year in prison, and the spouse whose account you entered can sue you for damages on top of that. The twist most people don’t expect: the emails you took may still end up usable in a divorce case, even though taking them was illegal.
The Federal Law That Applies
The main statute is the Stored Communications Act, part of the Electronic Communications Privacy Act of 1986. Codified at 18 U.S.C. § 2701, the SCA makes it a crime to intentionally access a facility that provides electronic communication service without authorization and obtain a stored communication.1Office of the Law Revision Counsel. 18 U.S. Code 2701 – Unlawful Access to Stored Communications Logging into your spouse’s Gmail or Yahoo account without permission and reading their messages fits that description.
The statute covers any message held by an email provider, whether it’s a new email sitting in the inbox or an older one kept as a backup.2Office of the Law Revision Counsel. 18 USC 2510 – Definitions The age of the message doesn’t matter.
A second federal law, the Wiretap Act at 18 U.S.C. § 2511, applies when someone captures a communication while it’s being transmitted rather than after it lands in storage.3Office of the Law Revision Counsel. 18 USC 2511 – Interception and Disclosure of Wire, Oral, or Electronic Communications Prohibited Installing spyware or a keylogger on your spouse’s device to capture messages in real time moves the conduct toward Wiretap Act territory. Penalties there run up to five years in prison for any violation, with no first-offense discount.
A third federal statute, the Computer Fraud and Abuse Act at 18 U.S.C. § 1030, prohibits accessing a computer without authorization to obtain information.4Office of the Law Revision Counsel. 18 U.S. Code 1030 – Fraud and Related Activity in Connection With Computers If your spouse never gave you access to their email account, logging in is unauthorized access under this law too. The Supreme Court narrowed the CFAA in Van Buren v. United States in 2021, holding that “exceeds authorized access” means getting into areas of a system that are off-limits entirely, not using legitimate access for an improper purpose.5Supreme Court of the United States. Van Buren v. United States, No. 19-783 A private email account you were never invited into is off-limits.
State Computer Crime Laws Stack on Top
Nearly every state has its own computer crime statute, often labeled computer trespass or unlawful computer access. These laws typically prohibit intentionally accessing a computer, network, or electronic communication system without permission. A few go further than the federal statutes and specifically address intercepting communications in transit alongside accessing stored data.
One act of logging into a spouse’s inbox can trigger a federal charge and a state charge at the same time, each with its own penalties.
What Counts as Permission
Authorization is the whole question, and courts read it narrowly. Knowing or guessing the password is not permission. Having been given the password once for something else, like checking a flight confirmation or logging into a streaming account, is not permission. Permission has to be clear, current, and specific to reading private messages.
A shared computer doesn’t change the analysis. A password-protected account on a shared laptop is still a private account. One federal court described the point this way: negligence in leaving an account accessible is not the same as approval. Forgetting to log out is not an invitation to read what’s inside.1Office of the Law Revision Counsel. 18 U.S. Code 2701 – Unlawful Access to Stored Communications
Past consent also runs out. If the two of you shared email access earlier in the marriage but have since separated, the separation ends the consent. Courts look at the moment of access, not at the history of the relationship.
Criminal Penalties
The SCA uses a tiered structure based on motive and prior history:
- First offense without an aggravating motive: up to one year in prison and a fine.
- First offense committed for commercial gain, malicious damage, or in furtherance of another crime: up to five years and a fine.
- Repeat offense without an aggravating motive: up to five years.
- Repeat offense with an aggravating motive: up to ten years.1Office of the Law Revision Counsel. 18 U.S. Code 2701 – Unlawful Access to Stored Communications
Most spousal snooping lands in the first category: up to a year. The exposure climbs if a prosecutor characterizes the access as being for private gain, such as pulling emails to improve a divorce settlement or hurt a spouse’s business.
Civil Damages Your Spouse Can Collect
Criminal charges are not the only risk. The SCA gives the person whose account was accessed a private right of action. A successful plaintiff can recover actual damages plus any profits the violator earned, with a guaranteed minimum of $1,000. Courts can add punitive damages for willful violations, plus attorney fees.6Office of the Law Revision Counsel. 18 U.S. Code 2707 – Civil Action
The Wiretap Act’s civil remedy is larger. A plaintiff can recover the greater of actual damages plus profits, or statutory damages of $100 per day or $10,000, whichever is more, along with punitive damages and attorney fees.7Office of the Law Revision Counsel. 18 USC 2520 – Recovery of Civil Damages Authorized The $10,000 floor makes Wiretap Act claims worth significantly more when actual damages are hard to pin down.
Can the Emails Still Be Used in Divorce Court?
Most people assume illegally obtained emails are automatically thrown out. They usually aren’t. The “fruit of the poisonous tree” doctrine is a constitutional rule that keeps the government from using evidence from unconstitutional searches in criminal prosecutions. It doesn’t apply to snooping by a private person, including a spouse, because no government agent was involved.8Office of Justice Programs. Admissibility of Evidence Located in Searches by Private Persons
Whether the emails come in depends on which statute was violated and whether that statute has its own exclusion rule. The Wiretap Act does: 18 U.S.C. § 2515 bars intercepted wire or oral communications from being used in any legal proceeding when disclosure would violate the statute.9Office of the Law Revision Counsel. 18 USC 2515 – Prohibition of Use as Evidence of Intercepted Wire or Oral Communications The provision names wire and oral communications and doesn’t explicitly cover electronic communications like email, and courts have reached different results on whether intercepted email is excludable.
The Stored Communications Act has no exclusion rule at all. Its remedies are criminal and civil only. Multiple federal courts have held that evidence obtained in violation of the SCA is not automatically inadmissible. Messages you printed out after logging into your spouse’s account may well be admissible in the divorce, even though logging in was a crime.
State law can change this. Some states have electronic privacy statutes that do exclude illegally obtained electronic communications from civil proceedings. And even where the evidence comes in, the judge now knows how it was obtained. In custody cases especially, a pattern of surveillance tends to work against the spouse who did it, no matter what the emails show.
Legal Ways to Get the Same Information
If the reason to snoop is a divorce or custody case, the lawful routes reach the same material without the criminal risk.
- Formal discovery: once a case is filed, either side can request documents from the other, including emails and texts. A judge can compel production if the other spouse refuses.
- Subpoenas to service providers: in some circumstances, a lawyer can subpoena records from the email provider, though federal privacy law limits what providers can hand over and typically requires a court order.
- Forensic examination: a court can order a neutral expert to examine devices or accounts, which protects both the evidence and its admissibility.
These paths take longer than opening an inbox at midnight, but the evidence is clean, admissible, and doesn’t put you in front of a prosecutor. A family law attorney can advise on which fits the situation.
Workplace Email Is a Different Picture
If your spouse uses an employer-provided email account, the privacy analysis shifts. Most employers maintain policies stating that employees have no expectation of privacy in company email and that the employer may monitor it. Personal messages your spouse sent through that kind of account may lose spousal privilege, because sending them through the employer’s system can count as voluntary disclosure to a third party. That doesn’t mean you can access the account yourself; the SCA and CFAA still apply. It does mean those messages may be more reachable through lawful discovery than messages on a personal account, because the employer may produce them in response to a subpoena.
