Power of attorney vs guardianship: which applies?

One is chosen; the other is granted. The records you owe follow from which.

Quick answer. A power of attorney is chosen: a capable principal signs a document appointing an agent, with whatever powers and limits the document contains — no court involved. Guardianship is granted: a court appoints someone after finding the person lacks capacity. A valid POA usually makes a guardianship unnecessary; when there is no POA, family must petition for guardianship. Agents owe an accounting on demand; estate guardians owe it to the court on a statutory schedule.

1. How each is created

	Power of attorney	Guardianship / conservatorship
Created by	The principal, while they have capacity — a signed (and in many states, witnessed/notarised) document	A court order after a petition and a finding of incapacity
Who is appointed	Whoever the principal chose — family, friend, professional	Whoever the court picks, usually weighing family order-of-preference statutes
Powers	Exactly what the document grants — broad or narrow, with optional gifting clauses	What the order grants, bounded by statute and local rules
Ends	Principal revokes it, dies, or (for a non-durable POA) loses capacity	Court terminates — death, recovery of capacity, or removal

A durable POA survives the principal’s incapacity — that is its whole point: the chosen agent keeps acting precisely when guardianship would otherwise be needed.

2. Who checks your work

This is the practical difference families underestimate:

An agent under POA is unsupervised until someone looks. The principal (while capable) can demand an accounting at any time; after incapacity or death, heirs, successor agents, Adult Protective Services, or a court can. The paper trail is your only defence.
A guardian of the estate reports to the court on a statutory schedule — accountings reviewed or audited, with contempt, removal, and surcharge for failures (in California, a 30-day notice to file escalates to contempt under Prob. Code §2620.2).

Paradox: the POA agent often has broader power and less built-in oversight — which makes disciplined self-accounting more important, not less.

3. The records each owes

POA agent: a transaction ledger with categories, a decision log with reasons, receipts for anything unusual, and an annual summary you can hand to the principal or family on request.
Estate guardian: the same ledger plus court-formatted schedules (receipts / disbursements / assets on hand), monthly reconciliation, asset valuations, and the underlying statements the filing must attach.

4. When one gives way to the other

POA exists: agents step in under the document; a guardianship is usually unnecessary unless someone contests the agent or the document fails.
No POA: family petitions for guardianship — a slower, costlier, public process that takes the choice away from the person it protects.
Guardianship in place, then a POA surfaces: the court decides; a validly executed POA predating incapacity often narrows what the guardian needs to manage.

Both roles keep records in the same shape. POA serves the agent’s ledger and annual summary; Guardian serves the court-side accounting.

FAQ

Does a power of attorney need to be filed with a court?

Generally no — it takes effect by signature (with witnessing/notarisation per state law) and is shown to banks when needed. It becomes part of a court record only if a dispute or guardianship proceeding arises.

Can a guardian override a power of attorney?

The court appoints the guardian knowing of the POA; depending on the order’s terms and state law, the guardianship can supersede or coexist with the agent’s authority. A valid, undisputed durable POA usually means no guardianship is needed at all.

Which one has more oversight?

Guardianship: the court reviews accountings on a statutory schedule. A POA agent is largely unsupervised until a family member, heir, or agency looks — so self-imposed record discipline matters more.

Can the same person be both agent and guardian?

Yes — commonly a family member is the agent under a POA and later the guardian. The accounting duties differ by role, so keep the records separated by which hat you were wearing.
