What is required for an advanced directive to be legally recognized?

For an advanced directive to be legally recognized, it must be written. A written document clearly articulates an individual's wishes regarding medical treatment and interventions in situations where they may be unable to communicate these decisions themselves. This requirement is crucial as it provides a tangible record of the person's preferences for healthcare, ensuring that their choices are respected and followed by healthcare providers.

While notarization, signatures from family members, or witnessing by a legal representative may add layers of credibility or compliance in certain contexts, they are not universally required for an advanced directive to be considered valid. Therefore, the paramount requirement is that the directive is documented in writing. This allows for a clear understanding and legal affirmation of the individual's healthcare preferences.
