Power of Attorney in California: Why You Need One (and What to Include)
A power of attorney is one of the most practical parts of an estate plan—because it’s about protecting you while you’re alive. If you become ill, injured, or otherwise unable to manage your finances, a properly drafted power of attorney can allow a trusted person to step in and handle urgent tasks without court involvement.
It helps avoid a court conservatorship: Without the right authority in place, your family may have to go to court to get permission to manage your finances.
Why it matters
- • It helps avoid a court conservatorship: Without the right authority in place, your family may have to go to court to get permission to manage your finances.
- • It allows time-sensitive tasks to get done: Paying bills, managing accounts, handling insurance issues, and addressing property matters often can’t wait.
- • It reduces stress and conflict: Clear written authority can prevent delays and disagreements during an already difficult time.
Common life events that should trigger a review
Review (or create) your power of attorney when life changes—and at least every few years to make sure it still matches your wishes.
- • Marriage, divorce, or separation
- • Buying or selling a home
- • Starting or selling a business
- • Moving (especially into or within California)
- • A new diagnosis or major health event
- • A change in your financial picture (inheritance, new accounts, retirement)
- • A change in who you trust to serve (relocation, relationship changes, or death)
Common mistakes people make
- • Using a generic form that doesn’t match your goals: Many people sign something that is too limited (or too broad) without understanding the consequences.
- • Naming the wrong agent (or no backup): If your first choice can’t serve and there’s no alternate, your plan can fail when you need it most.
- • Not clarifying when powers begin: Some powers of attorney are effective immediately; others are triggered by incapacity. The right choice depends on your situation.
- • Failing to address real-world tasks: If your agent can’t access accounts, manage real property, or work with a business, the document may not solve the problem.
- • Not coordinating with the rest of your estate plan: Your power of attorney should align with your trust, beneficiary designations, and overall plan.
What to do next
- Choose your agent carefully (and name at least one alternate).
- Make a list of the tasks your agent may need to handle (banking, taxes, real estate, business matters, benefits, etc.).
- Decide whether the power should be effective immediately or only upon incapacity.
- Work with an estate planning attorney to tailor the authority and safeguards to your situation.
- Store the signed document securely and tell your agent how to access it if needed.
