Also known as:physical evidences · real evidence · tangible evidence
Written by attorneys · grounded in primary & secondary sources — see below
Tangible objects or materials that a party offers to prove a fact in a legal proceeding. The category encompasses items such as weapons, bodily fluids, documents, and other physical items that exist independently of any witness statement. Courts distinguish physical evidence from testimonial communications because compulsion to produce the former does not implicate the privilege against self-incrimination.

How it applies
Common Examples

Alternative Source of Semen
Priscilla Parks alleged that Parker Phillips assaulted her after a conference. A rape kit recovered semen and abrasions. Phillips sought to introduce evidence that Parks had consensual sex with another scientist earlier the same day to show that the scientist, not Phillips, was the source of the semen. The court admitted the evidence under the exception allowing specific instances of the victim's sexual behavior when offered to prove an alternative source of physical evidence.
Attorney Conceals Client Evidence
Piper Patel, charged with robbery, gave her lawyer Pamela Phillips a bag containing stolen cash and a handgun. Phillips placed the items in a new safe deposit box without notifying authorities. When investigators later traced the items to Phillips, the court held that the attorney-client privilege did not protect the physical evidence and that Phillips could face sanctions for obstructing access.

Lawyer Removes Evidence Location
Paul Peterson told his lawyer Paula Pierce the location of a bloody shirt hidden in a park. Pierce retrieved the shirt, had it tested, and then turned it over to prosecutors. The court ruled that the communication about the location remained privileged, but the shirt itself lost protection once Pierce removed and altered it, requiring turnover to law enforcement.
Attorney Holds Knife for Testing
Premier Manufacturing's employee Parker Phillips told counsel that a knife used in an assault was in a warehouse. Counsel retrieved the knife, examined and tested it for two weeks, and then delivered it to police. The court held that the physical knife was not privileged and had to be surrendered after a reasonable period for defense preparation, while the communication about its location stayed protected.
Blood Draw Produces Physical Evidence
After a car accident, officers directed a hospital to draw blood from Pamela Phillips without a warrant. The sample revealed a high blood-alcohol level. The court held that the blood draw produced physical evidence rather than compelled testimony, so the Fifth Amendment privilege did not bar its admission.
Schmerber v. California384 U.S. 757 (1966)
Destruction of Saliva Sample
After a sexual assault conviction, Paul Peterson claimed that the government destroyed a saliva sample that could have exonerated him. The court treated the sample as physical evidence whose loss raised due-process concerns separate from any testimonial privilege, requiring analysis of whether the destruction was in bad faith.

Common questions
Frequently Asked
3
Does the attorney-client privilege protect physical evidence obtained from a client?+
No. The privilege protects only communications, not the physical evidence itself. When counsel takes possession of items such as weapons or documents, the items must generally be turned over to authorities after a reasonable period for examination.
Supporting sources
When may a defendant introduce evidence of a victim's other sexual conduct to explain physical evidence?+
In a criminal sexual-misconduct case, evidence of specific instances of the victim's sexual behavior is admissible if offered to prove that someone other than the defendant was the source of semen, injury, or other physical evidence.
Supporting sources
How does the Fifth Amendment treat compulsion to produce physical evidence versus testimony?+
The privilege against self-incrimination bars compelled communications or testimony but does not bar compulsion that makes the suspect the source of real or physical evidence such as fingerprints, blood samples, or measurements.
