What Is a Power of Attorney?

A power of attorney, often abbreviated POA, is a legal document in which one person, called the principal, authorizes another person, called the agent or attorney in fact, to act on the principal's behalf. The agent does not need to be a lawyer. The document is a core tool in estate planning and elder law, and paralegals frequently help prepare, review, and manage these instruments. Because the topic touches agency law, fiduciary duty, and state statutes, it is a favorite on paralegal certification exams.

What Are the Main Types of Power of Attorney?

General Power of Attorney

A general POA grants the agent broad authority over the principal's financial and legal affairs, such as banking, paying bills, managing property, and filing taxes. A traditional general power of attorney ends if the principal becomes incapacitated, which limits its usefulness for long term planning.

Limited or Special Power of Attorney

A limited POA grants authority for a specific transaction or a defined period. A common example is authorizing someone to sign closing documents on a home sale when the owner cannot attend. It ends when the task is complete or the stated period expires.

Durable Power of Attorney

A durable POA continues in effect after the principal becomes incapacitated. Most states require express language stating that the authority survives incapacity, such as "this power of attorney shall not be affected by subsequent disability or incapacity of the principal." The Uniform Power of Attorney Act, adopted in many states, makes powers of attorney durable by default unless the document says otherwise.

Springing Power of Attorney

A springing POA takes effect only upon a specified event, usually the principal's incapacity. The document must explain how incapacity is determined, often by the written opinion of one or two physicians. Springing powers can cause delays and disputes, since third parties may hesitate to accept the agent's authority until the triggering event is proven.

Health Care Power of Attorney

Also called a health care proxy or durable power of attorney for health care, this document authorizes an agent to make medical decisions when the principal cannot. It is separate from a financial POA and is frequently paired with a living will, which states the principal's wishes about end of life treatment.

What Formalities Are Required?

Requirements vary by state, but a valid POA generally requires that the principal have capacity, that the document be in writing, and that it be signed. Many states require notarization, witnesses, or both. Real estate transactions typically require a POA that is notarized and recorded with the county recorder. Financial institutions often have their own forms and may scrutinize documents they did not draft, so planning ahead with the institutions the agent will deal with can prevent problems.

What Powers Can Be Granted?

The document defines the scope. Typical powers include:

Banking and investment transactions
Real property sales, purchases, and leases
Tax matters and filings
Insurance claims and benefits
Litigation and claims management
Business operations
Retirement accounts and government benefits

Some powers are considered sensitive, and many statutes require them to be expressly stated. These often include making gifts, creating or changing a trust, changing beneficiary designations, creating survivorship rights, and delegating authority to another person. An agent cannot be granted the power to make or change the principal's will, since a will must be executed by the testator personally.

What Duties Does an Agent Owe?

An agent is a fiduciary and owes the principal duties of loyalty, good faith, and care. The agent must act within the scope of authority, keep the principal's property separate from their own, avoid conflicts of interest, keep accurate records, and act in the principal's best interest. Self dealing is prohibited unless clearly authorized. An agent who breaches these duties may be liable for damages, removed by a court, and in some cases subject to criminal or elder abuse penalties.

Is an Agent Entitled to Compensation?

Most statutes allow reasonable compensation and reimbursement of expenses unless the document says otherwise. Family members frequently serve without pay, but the document should address the issue to avoid disputes.

When Does a Power of Attorney End?

A power of attorney terminates upon any of the following events:

Death of the principal. Authority ends immediately. After death, the executor or personal representative takes over, not the former agent.
Revocation by the principal while the principal has capacity. Notice should be given to the agent and to third parties who have relied on the document.
Incapacity of the principal, if the POA is not durable.
Expiration of the stated term or completion of the specific purpose.
Court order or the appointment of a guardian or conservator, depending on state law.
Resignation, death, or incapacity of the agent when no successor is named.
Divorce, in many states, if the spouse was named agent.

How Does a POA Differ from a Will, Trust, or Guardianship?

A will operates only after death. A revocable living trust can hold property during life and continue after death, with a trustee managing assets. A POA operates during the principal's life and conveys authority, not ownership. A guardianship or conservatorship is a court supervised process used when no valid POA exists and the individual is incapacitated. It is more expensive, public, and time consuming, which is a major reason lawyers encourage clients to sign durable powers of attorney while they have capacity.

What Is the Paralegal's Role?

Under attorney supervision, a paralegal may gather client information, prepare drafts from firm templates, coordinate execution ceremonies with witnesses and notaries, maintain original documents, and explain logistical steps. Paralegals must not give legal advice, such as recommending which powers to grant or whom to choose as agent. Doing so may constitute unauthorized practice of law.

Exam Tips

Remember that durability must be stated or provided by statute, that a springing POA depends on a trigger event, that death ends all POAs, and that agents are fiduciaries. Practice distinguishing health care directives from financial powers.
