You’re staring at an MBE Evidence question about a husband refusing to testify against his wife, and you freeze. Was that spousal privilege? Or marital communications privilege? Or are those the same thing? You pick an answer, move on, and hope for the best. But here’s the problem: the bar examiners love testing the distinction between these two privileges, and most students blur them together until it costs them points.
Let’s fix that right now.
The Core Distinction: Two Separate Privileges
The confusion is understandable. Both privileges involve married couples. Both appear in Evidence questions. Both have similar-sounding names. But they protect completely different things, operate under different rules, and have different holders.
Spousal privilege (also called spousal immunity or testimonial privilege) protects a spouse from being forced to testify at all against the other spouse in a criminal case. The witness spouse holds this privilege and can refuse to take the stand entirely.
Marital communications privilege protects confidential communications made during the marriage. Either spouse can invoke this privilege to prevent disclosure of what was said in private, and it applies in both civil and criminal cases.
Think of it this way: spousal privilege is about whether someone testifies. Marital communications privilege is about what someone testifies about.
Spousal Privilege: The Witness Decides
Spousal privilege only applies in criminal proceedings. If your spouse is a defendant, you cannot be compelled to testify against them. Period. But here’s the critical detail that separates weak answers from correct ones on the MBE: the witness spouse holds the privilege, not the party spouse.
That means if you want to testify against your spouse, you can. Your spouse cannot stop you. The prosecution cannot force you, but they also cannot be blocked by the defendant from calling you if you’re willing.
Requirements for spousal privilege:
- The marriage must be valid and ongoing at the time of trial
- The case must be criminal
- The testimony would be against the other spouse
Key limitations:
- Does not apply if the spouses are divorced at the time of trial (even if they were married when the crime occurred)
- Does not apply in cases where one spouse is charged with a crime against the other spouse or the spouse’s children
- Does not cover observations or actions, only the compulsion to testify
Here’s how the MBE tests this. Husband is on trial for bank robbery. Prosecution calls Wife to testify that she saw Husband counting large stacks of cash the night of the robbery. Husband objects on grounds of spousal privilege. What result?
The objection fails. Why? Because Wife holds the privilege, not Husband. If Wife wants to testify, Husband cannot assert spousal privilege to stop her. The privilege belongs to the witness spouse, and she’s waiving it by taking the stand.
Now flip it: same facts, but Wife refuses to testify and the prosecution tries to compel her. Now the privilege applies. Wife can invoke spousal privilege and refuse to testify at all in the criminal case against Husband.
Marital Communications Privilege: What Was Said in Confidence
Marital communications privilege operates completely differently. This privilege protects confidential communications made between spouses during the marriage. Either spouse can assert it to block testimony about what was said privately.
Requirements for marital communications privilege:
- The communication was made during a valid marriage
- The communication was confidential (intended to be private between spouses)
- The privilege applies in both civil and criminal cases
Key distinctions from spousal privilege:
- Either spouse can invoke it (not just the witness)
- Survives divorce (protects communications made during the marriage even after it ends)
- Only protects communications, not observations or actions
- Applies in both civil and criminal proceedings
The MBE loves testing what counts as a “communication.” If Husband tells Wife “I robbed the bank,” that’s a communication protected by the privilege. But if Wife simply observes Husband counting cash, that’s not a communication. She can be compelled to testify about what she saw, even if Husband objects.
The confidentiality requirement matters too. If Husband confesses to Wife in front of his brother, there’s no reasonable expectation of privacy. The communication isn’t confidential, so the privilege doesn’t apply. Similarly, if Wife tells a friend what Husband said, she’s waived the privilege for that communication.
How the MBE Traps You
The bar examiners set traps by mixing elements of both privileges in a single fact pattern. You’ll see a question where the spouses are now divorced, one spouse wants to testify about a conversation, and the other spouse objects. Students who haven’t separated the privileges will panic.
Break it down: Are they divorced? Then spousal privilege doesn’t apply at all (it requires an ongoing marriage at the time of trial). But marital communications privilege survives divorce. Was the testimony about a confidential communication made during the marriage? If yes, the privilege applies. If the testimony is about an observation or action, no privilege protects it.
Another common trap: the question asks whether the witness spouse can be “compelled” to testify. That word signals spousal privilege, not marital communications privilege. Compulsion is about forcing someone to take the stand at all. If the question asks whether testimony about a specific statement can be blocked, that’s marital communications privilege.
Let’s test your understanding with a hypo. Husband and Wife are now divorced. Husband is on trial for tax fraud committed during the marriage. Prosecution calls Wife to testify that Husband told her “I’m hiding income from the IRS” during a private conversation in their bedroom. Husband objects. What privileges apply?
Spousal privilege: No. They’re divorced, so spousal privilege is gone. Even if they were still married, Wife is willing to testify, and she holds that privilege.
Marital communications privilege: Yes. The statement was a confidential communication made during the marriage. The privilege survives divorce. Either spouse can invoke it, so Husband’s objection succeeds. Wife cannot testify about what Husband said.
Change one fact: Wife testifies she saw Husband shredding documents in his home office. Husband objects on grounds of marital communications privilege. Now the objection fails. Shredding documents is an action, not a communication. The privilege doesn’t apply. Wife can testify about what she observed.
Exceptions That Apply to Both Privileges
Both privileges have a critical exception: they do not apply in cases involving crimes against the spouse or the spouse’s children. If Husband is charged with assaulting Wife, she can be compelled to testify and no privilege protects their communications about the assault.
This exception makes sense. The law won’t allow the marital privileges to shield domestic violence or child abuse. The MBE tests this by presenting a fact pattern where the defendant tries to invoke a marital privilege in a case involving harm to the family. The answer is always that the exception applies and the privilege fails.
Neither privilege protects communications or testimony about jointly participated crimes in some jurisdictions, though this varies. The MBE typically avoids this nuance unless it’s clearly stated in the fact pattern.
What to Memorize for Test Day
When you see a spousal privilege question, ask:
- Is this a criminal case? (Required)
- Are they currently married? (Required)
- Who holds the privilege? (The witness spouse)
- Is the witness willing to testify? (If yes, defendant cannot block it)
When you see a marital communications privilege question, ask:
- Was this a communication (not an observation)? (Required)
- Was it made during a valid marriage? (Required)
- Was it confidential? (Required)
- Does it matter if they’re divorced now? (No, privilege survives)
- Who can invoke it? (Either spouse)
The fastest way to lose points is treating these as the same privilege. They’re not. One is about compulsion to testify in criminal cases. The other is about protecting confidential marital conversations in any proceeding. One ends at divorce. The other survives it. One belongs to the witness. The other belongs to both spouses.
Locking It In
Spousal privilege and marital communications privilege show up repeatedly on the MBE, often in questions designed to punish students who memorized a vague rule about “husband and wife testimony” without understanding the mechanics. The distinction isn’t subtle once you see it clearly, but it requires active practice with hypos that test the boundaries.
If you want all the Evidence privileges organized for exactly this kind of active recall, FlashTables Evidence breaks down both privileges with their elements, exceptions, and key distinctions in a structured two-column format. You’re not reading paragraphs hoping the rule sticks. You’re drilling the components until you can spot which privilege applies in three seconds.
The privileges aren’t hard. They’re just tested in ways that expose whether you actually understand the difference or just recognized the words “spousal” and “privilege” and guessed. Don’t guess. Know which privilege controls, who holds it, and when it applies. That’s how you pick up points everyone else is leaving on the table.
