Power of Attorney
Power of Attorney Explained
Understand the different types of power of attorney — general, durable, healthcare, and limited — and when each is appropriate.
What is a power of attorney?
A power of attorney (POA) is a legal document that authorizes one person (the agent or attorney-in-fact) to act on behalf of another person (the principal). The scope, duration, and type of authority depend on the specific POA document.
General power of attorney
A general POA grants broad authority over financial and legal matters. It typically ends if the principal becomes incapacitated. Use a general POA when you need someone to handle a wide range of affairs for a defined period — for example, while you are traveling abroad.
Durable power of attorney
A durable POA remains in effect — or takes effect — if the principal becomes incapacitated. The word 'durable' means the authority survives incapacity. This is commonly used in estate planning to ensure someone can manage finances if you cannot. A durable financial POA is distinct from a healthcare power of attorney.
Healthcare power of attorney
A healthcare POA (also called a medical POA or healthcare proxy) authorizes an agent to make medical decisions on your behalf if you are unable to communicate your wishes. It often accompanies an advance healthcare directive or living will that records your treatment preferences.
Limited (special) power of attorney
A limited POA restricts the agent's authority to a specific transaction, property, or time period. For example, a limited real estate POA might authorize an agent to sign closing documents for one property on one date. Locke Direct offers a Limited Real Estate Power of Attorney for this use case.
Choosing the right type
Consider what authority you need to grant, for how long, and whether it should survive incapacity. A limited POA is appropriate for a single transaction. A durable POA is appropriate for long-term planning. Do not treat all POAs as interchangeable — each serves a distinct legal purpose.
Frequently asked questions
Can I revoke a power of attorney?
Yes. As long as you are mentally competent, you may revoke a POA at any time by providing written notice to the agent and any institutions relying on it. A revocation should be in writing, signed, and dated.
Does a power of attorney need to be notarized?
Requirements vary by state and by POA type. Many states require notarization and sometimes witnesses. A POA used for real estate transactions typically must be recorded. Locke Direct's guided products apply your state's execution requirements.
