Marital communications privilege protects confidential spousal communications from compelled disclosure, with narrow exceptions for interspousal suits and domestic crime prosecutions. The provision creates a marital communications privilege: a person who is or has been married cannot be compelled to disclose, nor permitted to disclose, communications made to them during marriage by the other spouse, unless the communicator or the communicator's representative in interest consents; the privilege does not apply in suits between married persons or in proceedings where one married person is prosecuted for a crime committed against the other.
