What type of consent involves allowing a legally authorized representative to sign for the subject?

The concept of informed consent is central to ethical research and medical practices. It requires that individuals have a clear understanding of the procedure or study, including its risks, benefits, and alternatives, and that they voluntarily agree to participate. In situations where a subject may be unable to provide consent themselves—perhaps due to age, mental capacity, or other limitations—a legally authorized representative can step in to provide informed consent on their behalf. This ensures that the decision-making process respects the rights and interests of the individual who is unable to give consent directly, while still adhering to the principles of autonomy and informed participation.

Informed consent maintains a commitment to ethical standards, ensuring that all parties involved are protected and that there is transparency in the process. It's crucial that the representative is legally recognized to make such decisions, which reinforces the integrity of the consent process.
