How do I prove my child doesn’t have the capacity to sign a new medical power of attorney? – North Carolina

Short Answer

In North Carolina, the key issue is whether the person has enough understanding and capacity to make and communicate health care decisions at the time a new Health Care Power of Attorney is signed. If a child (now an adult) cannot understand the document or cannot reliably communicate a choice, medical records and a clinician’s written capacity opinion can be strong evidence. If a relative is trying to force a change, the most reliable way to stop it is often a Clerk of Superior Court incompetency/guardianship case so there is a court order establishing who has authority.

Understanding the Problem

Under North Carolina guardianship law, the decision point is whether an adult child can legally sign a new Health Care Power of Attorney when communication limits raise concerns about capacity. The practical goal is to prevent a different relative from using a new document to replace an existing health care decision-maker structure. The question usually turns on what the adult child can understand and communicate at the time of signing, and what proof will be accepted by medical providers or the Clerk of Superior Court if a dispute becomes a court case.

Apply the Law

North Carolina allows an adult to create a Health Care Power of Attorney only if the person has the understanding and capacity to make and communicate health care decisions. Capacity is time-specific: the focus is what the person could understand and communicate when the document was signed. Separately, North Carolina law also provides a court process (before the Clerk of Superior Court) to adjudicate incompetence and appoint a guardian, which can create clear legal authority and reduce the risk of last-minute document changes.

Key Requirements

  • Decision-making understanding: Evidence should show the adult child cannot understand what a Health Care Power of Attorney does (naming an agent to make medical decisions) or cannot grasp the basic consequences of signing a new one.
  • Ability to communicate a choice: Evidence should show the adult child cannot consistently communicate a health care choice (including the choice of agent) in a reliable way, even with appropriate supports.
  • Proof tied to timing: The strongest proof connects the limitations to the specific time a new document was signed (or attempted), using medical documentation, clinician opinions, and witness observations.

What the Statutes Say

Analysis

Apply the Rule to the Facts: The facts describe an adult child with very limited ability to communicate, which directly relates to North Carolina’s requirement that the person be able to make and communicate health care decisions to sign a new Health Care Power of Attorney. If the adult child cannot reliably communicate a consistent choice of agent (or cannot understand what changing agents means), that supports a lack of capacity to sign a new document. Because another relative is pushing for a change despite an existing decision-maker structure, the most effective “proof” is usually documentation and, if needed, a Clerk of Superior Court order that clarifies who has authority.

Process & Timing

  1. Who files: Typically a parent, caregiver, or other interested person. Where: The Clerk of Superior Court in the county where the adult child resides or is present in North Carolina. What: A verified petition to adjudicate incompetence and (if appropriate) to appoint a guardian. When: As soon as there is a real risk someone will try to obtain a new Health Care Power of Attorney or a revocation.
  2. Build the capacity record: Gather recent medical records that describe diagnosis, functional limits, and communication ability; request a clinician letter that addresses whether the adult child can understand and communicate health care decisions and whether the limitations are consistent over time. Also gather neutral witness observations (for example, from care staff) focused on communication and understanding, not family conflict.
  3. Use the court order to prevent “document shopping”: If the Clerk adjudicates incompetence and appoints a guardian, the guardian’s authority can provide a clear point of reference for health care providers and reduce the chance a new document is treated as valid. The guardian can also give providers notice of the dispute and provide copies of existing directives and orders.

Exceptions & Pitfalls

  • “Limited speech” is not automatically “no capacity”: A person can have capacity even with disabilities if they can understand the choice and communicate it consistently (including through assistive communication). Proof should focus on understanding and reliable communication, not labels.
  • Capacity can vary by day: If the adult child has better and worse days, a relative may try to arrange signing on a “good day.” Medical documentation that addresses fluctuations (and what supports still do not allow reliable decision-making) can matter.
  • Notary/witness issues do not solve the core problem: A document can look properly signed and notarized and still be challenged if the signer lacked capacity. Conversely, arguing only about family conflict (instead of capacity evidence) often weakens the case.
  • Notice problems: Even if a revocation is claimed, North Carolina law requires communication to the existing agent and the attending physician/eligible psychologist before it becomes effective. Disputes often arise because providers never received clear notice.

Conclusion

In North Carolina, stopping a new medical power of attorney usually comes down to proving the adult child lacked the understanding and capacity to make and communicate health care decisions at the time of signing. Strong proof typically includes medical documentation and a clinician opinion focused on understanding and communication, tied to the relevant time period. When a relative is pushing a change, the most reliable next step is often to file a verified incompetency petition with the Clerk of Superior Court so there is a court order clarifying who has authority.
