Key Differences Between a General Power of Attorney and a Healthcare Power of Attorney

Estate planning is more than just deciding who gets what after someone passes away. It's about preparing for life's uncertainties and making decisions now that'll carry legal authority later. Among the most important legal documents we prepare for at Porter Law Firm in Mount Pleasant, South Carolina, are powers of attorney.
These documents allow individuals to designate someone else to act on their behalf in various situations. While both general and healthcare powers of attorney serve this purpose, they address very different needs.
Knowing how these two documents differ is essential to building a complete estate planning strategy. Each one serves a distinct legal function and can impact financial and medical decisions during a person’s lifetime. South Carolina law recognizes both types and provides the legal structure to make them enforceable when properly executed.
As we work with clients and families throughout the estate planning process, we take time to explain the purpose of each document so that our clients are confident about the authority they're granting.
A general power of attorney gives someone broad authority to manage financial and legal matters on another person’s behalf. Under South Carolina law, this authority can cover everything from banking transactions and property management to signing contracts and filing taxes.
We often help clients prepare general powers of attorney as part of a larger estate planning strategy, especially when they want to make sure someone trustworthy is empowered to handle their affairs if they become incapacitated.
This kind of document becomes especially important when someone faces temporary or permanent disability. Rather than going through the court process to appoint a conservator, the agent named in a general power of attorney can immediately step in and act.
This helps avoid delays, confusion, and unnecessary legal expenses. The person granting the power, known as the principal, can decide how much authority to give and when it should begin.
Some clients prefer a durable general power of attorney, which remains effective even if the principal becomes incapacitated. Others prefer that the authority begin only under specific circumstances.
When we build estate planning packages, we include general powers of attorney to make sure someone is authorized to handle important financial decisions. Without this document, loved ones may have to petition the court to gain control, which can be emotionally and financially draining during an already difficult time.
Unlike the general power of attorney, a healthcare power of attorney—also called a medical power of attorney—is focused solely on decisions related to medical care. South Carolina law allows individuals to name someone else to make healthcare decisions on their behalf if they become unable to do so themselves.
This document becomes essential in the following situations:
Someone is unconscious.
Someone is incapacitated.
Otherwise unable to express their wishes regarding medical treatment.
When we meet with clients to develop their estate planning documents, we explain that a healthcare power of attorney doesn't grant the agent any financial or legal authority.
Its scope is limited to healthcare decisions such as approving medical procedures, choosing treatment options, selecting healthcare providers, and making end-of-life decisions.
For this reason, we encourage every adult to have both a general power of attorney and a healthcare power of attorney, since they operate in entirely different areas.
One of the important features of the healthcare power of attorney is that it gives the designated agent the legal right to communicate with doctors and medical staff, even when HIPAA regulations would normally prevent disclosure.
Without this document, loved ones may be shut out of important conversations or decisions about care. As part of our estate planning services, we help clients understand who they trust most with such personal choices and guide them through selecting the right agent.
South Carolina recognizes both types of power of attorney as legally binding when executed properly. For a general power of attorney, the document must be signed by the principal and may need to be notarized depending on how it will be used.
In many estate planning matters, we recommend notarization to reduce the likelihood of challenges and to make the document easier to use with financial institutions.
Healthcare powers of attorney, on the other hand, must be signed in the presence of either two witnesses or a notary public. South Carolina law also allows individuals to include specific instructions within the document about medical preferences, such as whether to pursue life-sustaining treatment or not.
While those wishes can also be spelled out in a living will, many clients choose to combine these directives within the healthcare power of attorney for simplicity and clarity.
Both documents allow the principal to revoke the powers granted at any time, as long as they're still mentally competent. We explain these revocation procedures as part of every estate planning consultation to make sure clients retain control over their decisions.
One of the most important aspects of preparing these documents is choosing the right person to act as the agent. We often counsel clients to think carefully about who they trust with different aspects of their lives.
The person who's best equipped to handle financial transactions may not be the same person best suited to make medical decisions during a health crisis.
In estate planning, it’s not unusual to name different individuals for each type of power of attorney. Some clients choose a child or spouse for financial matters, but select a close friend or sibling with healthcare experience for medical decisions.
These choices are personal, and we help clients weigh the options based on their unique family dynamics and preferences.
We also discuss the importance of naming successor agents in case the original choice is unable or unwilling to serve when the time comes. Without this forethought, legal authority may lapse when it’s needed most. That’s why building flexibility into the estate planning process can protect our clients from unintended consequences later on.
While powers of attorney are primarily concerned with decisions made during life, they play a crucial role in comprehensive estate planning. Both the general and healthcare powers of attorney are designed to protect the principal’s interests and wishes when they can't act for themselves.
Without these documents in place, loved ones often face legal obstacles and emotional burdens during difficult periods.
We emphasize to every client that estate planning isn't just about preparing a will. It’s about making sure all the right legal tools are in place to handle whatever may happen, from illness to incapacity to end-of-life care.
The general power of attorney helps someone manage property, pay bills, and deal with institutions. The healthcare power of attorney helps someone make informed, compassionate medical decisions. Together, they create a safety net that brings peace of mind and legal clarity.
During the estate planning process, we also address how powers of attorney interact with other documents, such as living wills, HIPAA authorizations, and advance care directives.
These elements work together to reflect a person’s values and protect their autonomy. Without a complete legal structure, even a carefully drafted will may fall short of addressing the real challenges that arise during illness or incapacity.
At Porter Law Firm, we encourage clients not to wait until something happens to put powers of attorney in place. These documents only work if they're prepared in advance and properly executed under South Carolina law.
Far too often, we see families forced to go through time-consuming court proceedings because their loved one never completed the estate planning process. In those cases, the courts—not the family—decide who will take control.
Our goal is to help clients avoid that outcome by creating legally sound, personalized estate planning documents that reflect their wishes. Whether someone is updating existing documents or creating a plan for the first time, we walk them through each step and explain how these powers of attorney protect them now, not just in the future.
Preparing for incapacity isn't pessimistic. It's a practical and responsible part of living with intention. Powers of attorney give people a way to decide, in advance, who they trust to act in their best interests. That level of control is one of the most valuable outcomes of thorough estate planning.
At Porter Law Firm, we approach each estate planning engagement with attention to detail, helping clients choose the right tools for their needs and goals. We're proud to serve Mount Pleasant and Hilton Head Island, South Carolina. Call today to schedule a consultation.
