George Sr.: Don't worry, Michael. [conspiratorial whisper] They can't convict a husband and wife for the same crime!At a less enlightened point in legal history, a woman's legal identity was overtaken by her husband. One of the results of this, when mixed with another old legal concept (you could not testify at your own trial), was that a wife could not testify for or against her husband. As the rules regarding legal personage and testimony changed, this turned into a rule that one spouse could not give adverse testimony against the other. Over the course of the 20th century, this rule has continued to change, generally transforming into a sort of privilege for certain communications. Currently, in U.S. federal courts (other nations' courts and State courts frequently have a different, typically lesser, degree of protection), two spousal privileges exist:
Michael: Yeah, that's not true. At all.
George Sr.: Really? ...I have the worst f---ing attorneys.
Michael: Yeah, that's not true. At all.
George Sr.: Really? ...I have the worst f---ing attorneys.
- Marital confidences privilege: Any private conversation between spouses during the marriage, even if the two are later divorced, is not admissible as evidence, unless both allow its admission. There are exceptions to this; for example if both spouses are parties to a criminal conspiracy they can't invoke privilege to hide their conversations in furtherance of it.
- Spousal testimonial privilege: If one spouse is on trial, the other cannot be compelled to testify against the one on trial. "Compelled" is important here; if one spouse wants to, say, sell the other out to the cops, the spouse is free to do so (note that this is considerably different from other sorts of legally recognized privileges. In those cases, the party the information is adverse to has the control.) Unlike the Marital confidences privilege, the two have to be married at the time, but this privilege also covers things before marriage.
- Used as the Twilight Zone Twist in one The Twilight Zone comic. A man sells his soul with the understanding that he must be a horrible person. When he dies, he goes to Hell, where the Devil requires him to prove that he has been a horrible person. He calls his wife, whom he has abused terribly, as witness to his awfulness. However, she smilingly says that a wife cannot be compelled to testify against her husband, and the man is dragged off protesting by demons.
- Conspicuously inverted in The Clone Saga, specifically the miniseries "The Trial of Peter Parker". Mary Jane Parker is forced by the prosecution into the stand basically against her will, in clear violation of the spousal testimonial privilege.
- There is a Luke/Mara fanfic, where the New Republic wants to prosecute Mara for her crimes while serving as Emperor Palpatine's agent. Their only witness is Luke. Now, being a Jedi Master, he's not supposed to lie... so he marries her, and thus gains the right not to testify.
- Denied in the Elemental Chess Trilogy. Riza is the only person who can verify that her husband was nowhere near the scene of a crime when it happened - but her testimony is considered biased and therefore inadmissible in court. note
- In Angel Face (1952), Diane Tremayne conspires with chauffeur Frank Jessup to murder her parents by tampering with their car. Both Diane and Frank are arrested for the deaths, but they get married so they cannot be made to testify against each other.
- In A Song Is Born, Gangster Tony Snow wants to marry his moll girlfriend Honey Swanson just so she can't testify against him about a murder he committed.
- In The Nine Tailors by Dorothy L Sayers, the police won't allow William and Mary Thoday to marry until the case is resolved, as they might need her testimony against him.
- A major plot point in Agatha Christie's Witness for the Prosecution.
- In the Perry Mason book The Case of the Curious Bride, the defendant's husband has damaging testimony against her. His family does not approve of her, so they're trying to get the marriage annulled so his testimony will be admissible.
- A major plot point in Brighton Rock.
- In the Sidney Sheldon novel Master Of The Game, Keith blackmails Eve into marrying him by revealing that he knows she killed George Mellis (as revenge for brutally assaulting her several years prior). When he tells her that if they were married, he couldn't be forced to testify against her, she reluctantly agrees - but is infuriated when she realizes that they have to stay married because there's no statute of limitations on murder.
- In Weeds, Peter, who is a DEA agent, gets Nancy to marry him in Las Vegas to convince her that he won't try to arrest her for selling pot. The implication is that he'd be in huge trouble if his wife was a drug dealer, so he'd have a selfish reason to avoid arresting her rather than merely his word, but since he knew she was a drug dealer before they got married, the marital confidences privilege wouldn't apply and the spousal testimonial privilege wouldn't stop him from testifying if he wanted to. This of course doesn't cover the fact he legally blackmailed and coerced her into marriage (a legal contract), as well as a whole slew of other issues.
- In The Sopranos, Adrianna gets this idea from a late night crime show and proposes to Christopher so she can't testify against him. Unfortunately, some clarification from an actual lawyer points out the flaws in this plan.
- In Arrested Development, George Sr. (mistakenly) thinks that a husband and wife cannot be arrested for the same crime. When corrected by his son, he says "I have the worst fucking attorneys."
- This is a staple of Law & Order, which tends to ping pong around a bit between marital confidence and spousal testimonial privilege, depending on the needs of the episode.
- One notable example is the episode "Gov Love", which is about the interaction between spousal privilege and gay marriage, and where the spouse cannot be compelled to testify.
- In the earlier "Ego", a spouse who wants to testify can't because of the privilege.
- In another episode, [McCoy] tries to claim that spousal privilege has been nullified because a third party was present when a man divulged some pertinent information to his wife. Unfortunately, said third party was the couple's marriage counselor, which falls under "doctor-patient" privilege. McCoy then tries to claim that that privilege is void because of the presence of a third party, but the judge tells him he can't have it both ways.
- It also plays a role the 2009 season finale "The Drowned and the Saved", and many others.
- Law & Order: Special Victims Unit:
- One episode revolves around the concept that two villains had married their victims precisely to abuse spousal privilege, something with which they openly mock the detectives. Their overconfidence eventually backfires when investigations dig up a prior marriage license they hadn't gotten annulled, making their current marriages null and void.
- Another episode involves a serial rapist giving trophies from his victims (usually, jewelry) as gifts to his wife. He would ask her to wear the gifts during sex. She thought nothing of it until presented with all the evidence of the rapes. She agrees to testify, but is forbidden from giving any details regarding what her husband would have her do with the gifts, as the defense attorney argues that giving gifts to a spouse counts as private communication and is inadmissible as evidence. The prosecutor is limited to asking only details as to when and which gifts were given. During the trial, the wife gets upset that she's not being asked more and breaks down, revealing the truth. The judge declares a mistrial, and the husband goes free, until one of his earlier victims helps his wife shoot him "in self-defense".
- This happened on an episode of Murder One.
- The Closer used variations on both types, on different occasions.
- In the first instance, the wife claims spousal privilege so she can't be forced to testify against her husband, which Brenda tells her doesn't apply in this case, though in the end she testifies of her own will as part of a plea deal, as she had committed the murder at her husband's instigation.
- In the second instance, the wife, after being told that her husband is a war criminal and likely murderer, she, in a state of shock, relates how her husband came home covered in blood (which she presumed was from the assault on him), then invoked spousal privilege and told the police they couldn't act on the information in that conversation. Brenda complies, and tries to find probable cause to search for traces of blood, but in the end, they get around the spousal privilege by establishing that the husband used a fake name on his marriage certificate, thus nullifying the legality of the marriage and spousal privilege.
- Invoked in Downton Abbey, where Anna is forced onto the sidelines at Bates' trial.
- In Boardwalk Empire, Nucky marries Margret partly so she cannot testify against him in his trial for the murder of her first husband.
- In the Castle episode "Den of Thieves," they interview the wife of Esposito's allegedly Dead Partner, whom they suspect of the murder of the week. She points out that either he's really dead, in which case he didn't do it, or he's not, in which case they're still married and she can't be compelled to testify against him.
- Both POIs of the Person of Interest episode "Till Death" invoke this at the end. This was unusual in that the crime for which they were arrested was hiring hitmen to kill each other.
- In Breaking Bad, Skyler opts to go back on her desire to divorce Walt when she devises a cover story for his drug money so that it can go towards Hank's physical therapy, claiming it's so they can't be compelled to testify against one another.
- Averted by The Whole Truth-due to an exception, in the second episode the husband testifies against his wife.
- On One Life to Live, David blackmails Dorian into marriage so that neither of them can be forced to testify against each other regarding their obstruction of justice regarding Victor Lord's murder. It's a classic example of Hollywood Law; spousal privilege applies to things discussed during the marriage. Even married, what each of them knew about the other before the wedding is fair game.
- One of Al Capone's lieutenants, Jack McGurn, married his girlfriend - who was also his alibi for the St. Valentine's Day massacre - so she couldn't be compelled to testify about it in court.
- In Scotland, the privilege against self-incrimination extends to an admission of adultery. Similarly, a wife cannot be guilty of reset (selling or profiting from) of goods stolen by her husband.
