Power of Attorney (POA)
What Is Power of Attorney?
A Power of Attorney (POA) is a legal document that grants one person (the agent or attorney-in-fact) the authority to act for another person (the principal) in legal, financial, or medical matters.
A Power of Attorney is a cornerstone of estate planning and financial management. It allows someone you trust to handle your affairs if you are unable to do so yourself (due to illness, travel, or convenience). In the context of investing, a **Limited Power of Attorney (LPOA)** is standard. When you hire a portfolio manager or financial advisor, you sign an LPOA. This gives them the legal right to buy and sell securities in your account on your behalf. Crucially, an LPOA usually restricts them from withdrawing money or changing beneficiaries—they can only trade.
Key Takeaways
- The person granting power is the "Principal"; the receiver is the "Agent."
- It can be "General" (broad powers) or "Limited" (specific tasks like selling a house).
- A "Durable" POA remains in effect even if the principal becomes incapacitated.
- It is commonly used in trading to allow a financial advisor to manage an account.
- The authority typically ends upon the death of the principal.
- It is a fiduciary role; the agent must act in the principal's best interest.
Types of POA
Different powers for different needs.
| Type | Scope | Duration | Use Case |
|---|---|---|---|
| General POA | Broad (Financial/Legal) | Ends if incapacitated | Short-term help |
| Durable POA | Broad | Survives incapacity | Dementia/Coma planning |
| Limited POA | Specific (Trade/Sign) | Defined by document | Advisor trading account |
| Medical POA | Healthcare decisions | Starts at incapacity | Life support decisions |
Why Traders Need to Know This
1. **Discretionary Accounts:** If you want a broker to trade for you without calling you for permission on every trade, you must sign a trading authorization (a form of LPOA). 2. **Incapacity:** If a trader falls into a coma, their family cannot access or manage their trading account without a Durable POA. Without it, the account might be frozen until a court appoints a guardian, during which time positions could crash. 3. **Elderly Parents:** Managing finances for aging parents often requires a POA to deal with banks and brokerages.
The Bottom Line
Power of Attorney is the legal bridge for authority. Power of Attorney is a delegation of legal rights. Through authorizing an agent to act, it ensures continuity of management in financial affairs. For investors, the Limited POA is the standard tool for discretionary management, while the Durable POA is an essential safety net for personal incapacity.
FAQs
With a General POA, yes, they have the access. This is why you must choose someone trustworthy. With a Limited Trading POA, typically no—they can trade but cannot withdraw funds to their own account.
No. A POA is only valid while the principal is alive. The moment the principal dies, the POA expires, and the Will (or Trust) takes over.
Yes. As long as you are mentally competent, you can revoke a Power of Attorney at any time by notifying the agent and the institutions (banks/brokers) in writing.
A Springing POA only "springs" into effect when a specific event occurs, usually when a doctor certifies that you have become incapacitated. It offers privacy until needed but can cause delays.
The Bottom Line
Investors looking to delegate management or protect their estate must utilize the Power of Attorney. Power of Attorney is the legal authorization for agency. Through granting specific or broad powers, it allows life and business to continue when the principal cannot be present. Whether hiring a wealth manager (Limited POA) or planning for old age (Durable POA), it is a critical document. Without it, the legal system freezes assets for protection, which can be disastrous in volatile markets.
