Power-of-attorney-document-with-pen-and-gavel

Your elderly father granted your sister power of attorney (POA) to help manage his finances after a minor stroke. Now you're concerned she might use POA authority to change his will or redirect his assets away from the family's agreed-upon inheritance plan. This scenario raises important questions about POA limitations and the boundaries between different estate planning documents.

The short answer is no, a power of attorney directive can’t override a will, but the relationship between these documents requires careful examination to protect your family’s future. At Mark Ignacio Law, our San Diego estate planning lawyer helps you understand how various legal documents work together to protect your interests. 

Key Differences Between POA and Wills

These documents serve distinct purposes in estate planning, operating in different timeframes with separate areas of authority. They complement each other rather than compete for control over your affairs.

A POA grants someone authority to act on your behalf while you're alive. The person you designate as your agent can make financial decisions, sign documents, and handle various transactions according to the scope you define. However, your will only takes effect after your death.

Here’s what to remember: your power of attorney agent can’t change your will because they lack authority over testamentary documents. POA authority ends immediately upon your death, while your will's instructions begin at that moment.

What Your POA Agent Can’t Do

Similar to advanced health care directives, assigning someone with power of attorney authority gives you the assurance that your specific wishes for future care are honored. However, a POA also has important boundaries that protect your fundamental rights and estate planning decisions. A POA agent doesn’t have the power to: 

  • Change your will. They can’t modify, revoke, or create a new will on your behalf.
  • Alter beneficiaries. They also can’t change heirs to retirement accounts or life insurance policies without specific written authorization.
  • Make unauthorized gifts. Gift-giving powers require explicit authorization in your POA document.
  • Personal decisions. Marriage, divorce, voting rights, and medical treatment decisions are also outside the typical scope of a POA. 

Even a general power of attorney—which grants broad authority over financial matters—can’t override your testamentary wishes or fundamental estate planning decisions. Mark Ignacio is happy to discuss these factors in more detail as you work together to create a sound estate plan that reflects your full intentions. 

How POA Actions Might Affect Your Estate

While a power of attorney can’t directly override your will, certain actions by your agent may impact what remains in your estate for distribution. Here are just a few examples:

  • Medical expenses. Authorized spending on health care and long-term care reduces available assets for beneficiaries.
  • Investment decisions. Poor investment choices might diminish your estate's value, while successful management could increase inheritances.
  • Real estate transactions. Selling property to pay for care expenses changes the specific assets available for distribution.
  • Business operations. Decisions affecting business interests also influence what beneficiaries inherit.

These and other actions are likely why there is some confusion about how POA authority might affect your will and estate value. But you have a right to clearly define the powers of your agent.
