What Is the Difference Between Express and Implied Consent?

Consent can affect many legal issues, from medical treatment to contracts and personal injury claims. The way a person gives consent can also matter when a dispute occurs.

The difference between express and implied consent is how a person communicates agreement. Express consent is clearly stated through words or writing. Implied consent is shown through a person’s actions or the circumstances.

Express consent occurs when someone clearly communicates that they agree to something. Depending on the circumstances, express consent may be given verbally or in writing.

For example, a patient may sign a form agreeing to a medical procedure. A person could also verbally agree to let someone enter their property.

Express consent can be easier to prove because there may be direct evidence of the agreement. A signed document, recording, message, or witness may show what the person agreed to.

Implied consent is not directly stated. Instead, a person’s actions or the surrounding circumstances show that they agreed.

For example, a patient who holds out an arm after a nurse explains that blood will be drawn may be showing consent through their actions. The patient did not necessarily say “yes,” but their conduct may show agreement.

Whether implied consent exists depends on the facts. A person’s actions must reasonably show that they agreed to the conduct at issue.

The distinction becomes clearer when looking at everyday situations.

Examples may include:

  • Signing a surgical consent form as express consent
  • Verbally agreeing to a physical examination as express consent
  • Extending an arm for a routine blood pressure check as implied consent
  • Clearly telling someone they may use personal property as express consent

Consent is based on the specific situation. An agreement to one action does not always mean a person agreed to something different or more extensive.

Consent is especially important in healthcare. Patients generally have the right to make decisions about their own medical treatment.

Virginia law addresses when a patient or another authorized person may provide consent for medical care. It also provides rules for situations where a patient is unable to make a medical decision.

Before surgery or an invasive procedure, Virginia generally requires a practitioner to obtain informed consent from the patient. Informed consent generally involves giving the patient enough information to make a decision about the proposed care.

A signed form can provide evidence of consent, but the facts surrounding the treatment may still matter.

Yes. Consent to one act does not necessarily give permission for every related act.

For example, agreeing to one medical procedure does not automatically mean a patient agreed to a different procedure. The scope of the person’s consent can become important if an injury occurs.

Depending on the circumstances, a person may also withdraw consent. Continuing an activity after consent has clearly been withdrawn can raise different legal issues.

Virginia also uses the term “implied consent” in DUI law. This is different from the general concept of consent used in personal injury or medical cases.

Under Virginia’s implied consent law, a person who operates a motor vehicle on a Virginia highway is generally considered to have consented to chemical testing if arrested for certain DUI offenses within three hours of the alleged offense.

The statute has specific rules about testing and when implied consent applies. Refusing a required test can also have legal consequences.

Consent may become an issue when the defendant argues that the injured person agreed to an activity or accepted certain conduct.

For example, a dispute could involve a medical procedure, sporting activity, recreational event, or physical contact. The parties may disagree about whether consent was given and what it covered.

Evidence such as signed forms, messages, witness statements, and the parties’ actions may help establish whether consent was express or implied.
