How do I become someone’s power of attorney, and what does the other person need to sign for it to be valid? – South Carolina

Short Answer

In South Carolina, a person does not become another adult’s power of attorney by appointment from a court or by informal agreement. The other adult, called the principal, must sign a valid power of attorney document naming the agent, and the signing must meet South Carolina’s execution rules. For a financial power of attorney, that usually means the principal’s signature, two witnesses, and a notarized acknowledgment; for a health care power of attorney, the principal must sign and two qualified witnesses must sign, and the statutory form is commonly used.

Understanding the Problem

In South Carolina estate planning, the single issue is whether one adult can act as another adult’s chosen decision-maker and what the principal must sign to make that authority valid. The answer depends on which document is being created, because a financial power of attorney and a health care power of attorney serve different roles and follow different signing rules. The key trigger is the principal’s execution of a valid written document that names the agent and satisfies South Carolina law.

Apply the Law

South Carolina law treats a power of attorney as a written delegation of authority from the principal to an agent. A financial power of attorney covers non-medical matters such as banking, real estate, and other property or legal transactions. A health care power of attorney covers medical decisions when the principal cannot make or communicate those decisions. For financial powers, the main execution rule is that the principal must sign, the document must be witnessed with the same formalities as a South Carolina will, and it must be acknowledged or proved so it can be recorded like a deed. For health care powers, the document must be substantially in the statutory form, be dated, signed by the principal or at the principal’s direction in the principal’s presence, signed by at least two qualified witnesses, and it must identify the health care agent by name and address.

Key Requirements

Principal chooses the agent: Another adult cannot simply declare himself or herself to be the power of attorney. The principal must voluntarily name the agent in the document.
Proper signing formalities: A financial power of attorney generally needs the principal’s signature, two witnesses under will-signing rules, and a notarized acknowledgment or proof. A health care power of attorney needs the principal’s signature and two qualified witnesses, and the statutory form is commonly used.
Qualified agent and witnesses: For health care decisions, the agent must be an adult of sound mind, and certain people cannot serve as witnesses or, in some cases, as agent. Witness disqualifications matter because an otherwise signed document can still be challenged if the wrong people sign.

What the Statutes Say

S.C. Code Ann. § 62-8-105 (Execution of power of attorney) – sets the signing, witness, and acknowledgment rules for a financial power of attorney.
S.C. Code Ann. § 62-5-503 (Requirements for health care power of attorney) – lists the required contents, signature rules, witness rules, and agent qualifications for a health care power of attorney.
S.C. Code Ann. § 62-5-504 (Form of health care power of attorney) – provides South Carolina’s statutory health care power of attorney form and explains who may not serve as a witness.
S.C. Code Ann. § 62-5-517 (Document deemed to comply) – explains when a nonstatutory health care document will still be treated as compliant.

Analysis

Apply the Rule to the Facts: Here, the adult who wants authority over another adult’s medical and financial matters cannot obtain that role by request alone. The other adult must sign separate valid documents, or a properly drafted combined document where allowed, naming that person as agent for health care decisions and for financial matters. Because the facts involve both medical and non-medical authority, the safest approach is to confirm that each document uses the correct South Carolina signing formalities and clearly states the powers being granted.

For the health care document, South Carolina practice strongly favors using the statutory form because hospitals and providers are familiar with it, even though other compliant forms may also work. The witness rules are stricter than many people expect: the named health care agent cannot be a witness, and several relatives, beneficiaries, financially interested persons, and certain medical personnel are disqualified. For the financial document, the principal must have capacity to sign, and the document should be signed with will-style witnesses and a notary so third parties and recording offices will accept it, especially if real estate authority is included.

Process & Timing

Who files: the principal signs; the chosen agent does not appoint himself or herself. Where: usually in a lawyer’s office, notary setting, or other place where proper witnesses are present in South Carolina. What: a financial power of attorney for non-medical matters and a health care power of attorney, often using the statutory South Carolina health care form. When: before incapacity, because once the principal lacks capacity, a new power of attorney usually cannot be created.
Next, signed copies should be given to the agent and relevant institutions. For health care authority, a copy should be provided to the principal’s medical providers and included in the medical record when appropriate. For financial authority involving real estate, recording may be needed in the county Register of Deeds or Clerk of Court land records office so the document can be used in property transactions.
Final step and expected outcome: once the document is properly executed and accepted, the named agent can act within the powers granted. When signing on the principal’s behalf, the agent should sign in a representative capacity, such as the principal’s name by the agent as attorney-in-fact, to show the act is fiduciary rather than personal.

Exceptions & Pitfalls

A health care power of attorney can fail if the witnesses are disqualified, such as the named agent, certain relatives, a beneficiary, or certain treating medical personnel.
A financial power of attorney may be rejected by banks, title companies, or recording offices if it lacks proper witnesses, a notary acknowledgment, or clear authority for the transaction at issue.
People often assume one document covers everything. In practice, medical decision-making and financial decision-making are separate, and each document should be reviewed for scope, activation, and delivery to the right people. If no valid document exists after incapacity, court proceedings may be needed instead.

Conclusion

In South Carolina, becoming someone’s power of attorney requires the principal to sign a valid written document naming the agent and following the correct formalities for the type of authority granted. For financial authority, the key threshold is proper execution with witnesses and acknowledgment; for health care authority, the key threshold is a signed document in substantially the statutory form with two qualified witnesses. The next step is to have the principal sign the correct South Carolina forms before incapacity and distribute copies to the agent and any needed providers or institutions.
