Detailed answer — how this works under South Carolina law

South Carolina has adopted a version of the Uniform Power of Attorney Act. The Act sets the rules for how a principal (the person granting authority) creates a POA, what a POA can do, and how third parties should treat a POA. You can view the South Carolina statute chapter here: South Carolina Code — Uniform Power of Attorney Act (Title 62, Chapter 5).

Can someone who is incarcerated sign a POA?

Yes, incarceration alone does not automatically prevent a person from executing a valid POA. The key legal requirements are that the principal has the capacity to sign and that the document is executed in the required form (signed and properly acknowledged/notarized or witnessed per state requirements). If the principal lacks capacity (for example, severe cognitive impairment), a POA signed at that time may be invalid.

Formal execution requirements

Under the South Carolina statute, a power of attorney must be signed by the principal and typically should be notarized (acknowledged) so third parties will accept it. Many financial institutions insist on an original signed-and-notarized copy. If the principal is in a correctional facility, the facility may provide notary services or allow a notary to visit so the document can be acknowledged. Check facility rules and obtain certified copies for banks and other institutions.

Common financial powers that can be granted

A POA can be drafted to grant any or all of the following financial powers. To avoid confusion, list the powers you want explicitly in the document.

• Banking and cash management: Access and manage bank and credit union accounts; deposit and withdraw funds; endorse checks; open and close accounts (including online banking access if institutions allow).
• Bill payment and household expenses: Pay rent, mortgage, utilities, insurance, medical bills, and other recurring obligations.
• Benefits and government programs: Apply for, manage, and receive government benefits (Social Security, VA benefits, unemployment where applicable), and represent the principal before government agencies. Note: agencies like the Social Security Administration have their own procedures for representatives.
• Tax matters: Prepare, sign, and file federal and state tax returns on behalf of the principal; negotiate with tax authorities and make tax payments.
• Investment and portfolio management: Buy, sell, and manage stocks, bonds, mutual funds, and other investments.
• Real estate transactions: Buy, sell, mortgage, lease, manage, and convey real property — but real estate transactions often require additional formalities (recording the POA, institutional or title company requirements) and many institutions request a specially worded or recorded POA.
• Business operations: Run, sell, or close the principal’s businesses; sign business contracts; access business accounts — provided the POA explicitly grants those powers.
• Gifts and transfers: Make gifts or transfers of the principal’s assets if the POA specifically authorizes gifting. Because gifting can be abused, banks and courts scrutinize gifting powers closely.
• Safe-deposit boxes and tangible property: Access safe-deposit boxes and handle tangible personal property.
• Legal and claim actions: Hire attorneys, file or defend lawsuits, settle claims, and handle litigation on the principal’s behalf.

Common limitations and important exceptions

• Actions that require personal intent or testimony (making a will, signing a will, or voting in elections) generally cannot be accomplished through a POA.
• Some beneficiary designations (life insurance, retirement accounts) may be changed only by the named owner, and institutions often require additional documents before allowing changes by an agent.
• Financial institutions and title companies may refuse a POA they view as incomplete, unclear, or potentially fraudulent. South Carolina’s statute discusses third-party reliance and procedures for acceptance or refusal; see the statute chapter linked above.
• If the POA grants broad powers (especially gifting, transferring real property, or making gifts to the agent), banks and third parties often require strong, clear language and may ask for a recorded POA for real estate transactions.

Third-party acceptance and remedies

Under the Act, banks and other third parties generally should accept a valid POA but may request a certified copy or other proof. If a third party wrongfully refuses to accept a proper POA, the statute provides guidance on reliance and may create remedies; consult the chapter for details: SC Code — Uniform Power of Attorney Act.

Practical considerations while incarcerated

Plan ahead. Make a specific, durable POA (use the word “durable” or durable-language) so the POA remains effective if the principal later becomes incapacitated. Provide the agent with certified copies and a list of institutions to contact. Confirm whether the correctional facility allows a notary visit or provides notary services. Keep a clear record of who has copies of the POA and how it was delivered to banks or agencies.

Helpful Hints

• Use clear, specific language. List the exact powers you want to give (e.g., “authority to close account X and to sign checks on behalf of account X”).
• Make the POA durable — include wording that it remains effective despite later incapacity — to avoid future disputes.
• Have the POA notarized. Many South Carolina third parties will not accept an unsigned or unacknowledged copy.
• Ask the correctional facility about on-site notaries or procedures for outside notary visits. Some facilities accommodate legal documents for inmates.
• Provide certified copies to banks, investment firms, mortgage lenders, and any government agencies (Social Security, VA). Keep a record of when and to whom you gave copies.
• Consider successor agents. Name one or more successor agents in case the primary agent cannot act.
• Be cautious with gifting powers. Institutions and courts watch gifting carefully; limit this power unless you trust your agent completely.
• If a third party refuses a POA, ask for a written reason. You may need to seek legal help to resolve a wrongful refusal under the South Carolina statute.
• Keep an up-to-date inventory of accounts and paperwork so the agent can act efficiently.
• When possible, consult an attorney to draft or review the POA to ensure it meets institutional requirements and accomplishes your objectives.
