Final answer:
An individual must have legal guardianship or power of attorney to sign an enrollment application on behalf of a consumer. In voter registration, adults must affirm competency and may use state documents for online applications or sign a paper application.
Step-by-step explanation:
To sign an enrollment application on behalf of a consumer, the individual must have the authority to act as either a legal guardian or have power of attorney. Parents typically have this authority over their minor children and can provide consent on their behalf. In the case of voter registration, adults must affirm their competency to vote and, if completing the process online, must have identifying state documents for an online signature or affidavit to be accepted. A paper application may require a physical signature, which must be provided by the individual or a legally authorized representative.
