Under Utah's laws, which of the following is required for a valid power of attorney?

The requirement for a valid power of attorney in Utah is that it must be in writing and signed by the principal. This is aligned with the general principle that powers of attorney are legal documents that grant authority for one person to act on behalf of another, necessitating clear and documented consent from the principal to avoid ambiguities and disputes.

While notarization can add an additional layer of validation and may be required for certain types of transactions, it is not an absolute requirement for all powers of attorney in Utah. Similarly, a verbal agreement does not fulfill the requirements for a power of attorney, as the law necessitates written documentation to provide clarity and serve as evidence of the authority granted. Additionally, filing a power of attorney with the court is not typically required unless the document pertains to a specific legal proceeding.

Thus, the requirement of being in writing and signed by the principal is critical for establishing a valid power of attorney, making it the correct choice in this context.
