To plead the fifth means to invoke your Fifth Amendment right not to answer questions that might incriminate you.
Meaning
To “plead the Fifth” means invoking the right under the Fifth Amendment not to be compelled to be a witness against yourself in a criminal case. The amendment says no person “shall be compelled in any criminal case to be a witness against himself”.
Where it applies
Courtrooms, depositions, congressional hearings and police questioning.
How it works
A witness says, “I invoke my Fifth Amendment right” and declines to answer. Defendants in criminal trials don’t have to testify at all.
Miranda
Miranda v. Arizona (1966) requires police to inform suspects of this right.
Limits
It applies to testimony, not physical evidence such as fingerprints or documents in some cases.
Jury
In criminal trials, juries can’t infer guilt from silence.
Advice
Speak to a lawyer.
Meaning
“Pleading the Fifth” means invoking the Fifth Amendment to the US Constitution, which says that no person “shall be compelled in any criminal case to be a witness against himself.” A person can refuse to answer questions that might incriminate them. The right is also called the privilege against self-incrimination.
Where it applies

The privilege applies in criminal trials, grand jury proceedings, congressional hearings, depositions and civil cases when the answer could lead to criminal prosecution. It protects testimony, not physical evidence such as fingerprints, blood samples or documents (although there is an “act of production” doctrine for some documents). It applies to individuals, not corporations.
How it works
A witness is asked a question and says they decline to answer on the grounds that it may incriminate them. A judge decides whether the answer could reasonably be incriminating. Witnesses must claim it question by question, in most cases. A defendant in a criminal trial has an absolute right not to take the stand.
Miranda
In Miranda v. Arizona (1966), the Supreme Court held that police must tell suspects in custody that they have the right to remain silent, that anything they say can be used against them, and that they have the right to a lawyer. In Salinas v. Texas (2013), the Court held that a person who is not in custody must expressly invoke the privilege, and simple silence can be used against them.
Limits
- Immunity: if the government grants immunity, the witness can be forced to testify, since they can no longer be prosecuted on that testimony.
- Past conviction or when the statute of limitations has run out removes the risk.
- The privilege does not cover answering about others only, if the answer cannot incriminate you.
- Public school or employer questions can be different, but public employees cannot be fired solely for invoking the privilege in certain settings.
Jury
In a criminal trial, jurors are told not to hold a defendant’s silence against them. In civil cases, a jury may draw an adverse inference from invoking the Fifth.
Advice
If police or investigators want to question you, you can say clearly: “I am invoking my right to remain silent and I want a lawyer.” This is general information, not legal advice. Consult a licensed criminal defense attorney.
Constitutional basis and limits
The Fifth Amendment to the US Constitution, ratified in 1791, states that no person “shall be compelled in any criminal case to be a witness against himself.” Pleading the Fifth means refusing to answer a question because the answer could be self-incriminating. The 1966 Supreme Court case Miranda v. Arizona required police to inform suspects of this right before custodial interrogation. The right applies to testimony, not to physical evidence such as fingerprints or blood samples. In Salinas v. Texas (2013), the Court held that a person who stays silent without expressly invoking the right before being arrested may have that silence used in court. A witness may be given immunity, after which they can be compelled to testify. A defendant who chooses not to testify cannot have that silence used by the prosecution as evidence of guilt. Anyone facing questioning should speak with a licensed attorney.
