Almost every family reaches this question sideways. Nobody sits down one afternoon and decides to think about who signs paperwork for a parent's house. It arrives instead in the middle of something else — a hospital stay, a stroke, a slow year in which the mail stops getting opened — and it arrives with the assumption that because you are the son or the daughter, you are already allowed to act.
You are not, and that surprises people. Being family gives you no authority over someone else's real property. In California, authority over a home comes from a document, a court, or the owner's own signature. Nothing else.
This article walks through what that means in plain terms. It is not legal advice, and the questions here belong with an attorney who can look at the actual paperwork. What it can do is tell you which questions matter, so the conversation with counsel starts further along.
What a power of attorney actually is
A power of attorney is a document in which one person — the principal — names another person, the agent, to act on their behalf. It is a delegation, not a transfer. The principal still owns the house. The agent is simply permitted to do certain things with it.
Two features matter enormously here.
The first is DURABILITY. An ordinary power of attorney ends the moment the principal loses the ability to make decisions, which is precisely the moment families need it. A durable power of attorney is written to survive that, and it is the kind that is useful in the situations this article describes.
The second is SCOPE. A general financial power of attorney does not automatically carry authority over real property. Many do. Some do not, or carry it in narrow terms. Whether a particular document reaches a particular house is a question about that document's language, and it is one an attorney answers by reading it, not by assuming.
Why a title company reads it so carefully
Families are often startled by how much scrutiny a power of attorney gets in a real estate transaction. It can feel like distrust. It is not. Title insurance is a promise that ownership passed cleanly, and a signature made under a document that turns out not to have granted the authority is exactly the flaw that promise exists to catch.
Expect the original document to be requested rather than a copy. Expect questions about whether the principal is still living, because the authority ends at death and there is no grace period. Expect the specific language to be checked against the specific act. And expect any recording requirements to be handled properly, since a power of attorney used for real property is generally recorded alongside the transaction.
None of that is an obstacle to be worked around. It is the system doing the job it was built for, and the family that gets its paperwork reviewed by counsel early tends to find the whole process unremarkable.
The uncomfortable part: capacity
A power of attorney has to be signed while the principal understands what they are signing. That is the whole hinge. A document produced after capacity has genuinely gone is not a solution; it is a serious problem, and one that gets unwound later at considerable cost to everyone.
This is the argument for doing it early, in an ordinary week, when nothing is happening. Someone in good health signing a durable power of attorney is doing the least dramatic possible version of this task. Someone signing during a crisis is doing the hardest version, and sometimes the impossible one.
Capacity is also not a single switch. It varies by decision and it varies by day, and the question of whether a particular person could validly sign a particular document at a particular moment is a genuinely technical one. The article on building a support network without close family nearby covers the version of this problem where there is no obvious person to name at all.
Having authority is not the same as being right to use it
This deserves saying plainly, because it is where the real harm happens.
An agent under a power of attorney is a fiduciary. The authority exists to serve the principal's interests, not the agent's, and not the family's convenience. Selling a house because an agent believes it would be tidier is not the same as selling because the owner needs it or wanted it, and the difference is legally meaningful.
Some plain guardrails, none of them exotic:
- The principal's known wishes come first, including the wish to stay exactly where they are. Staying put is a legitimate outcome, and an agent's job includes protecting it.
- Money stays separate. Proceeds and accounts belong to the principal, never commingled.
- Keep records. Boring, contemporaneous notes about what was done and why are the best protection an honest agent has.
- Tell the other family members. Secrecy between siblings is where most disputes germinate, and the family meeting guide is a decent template for getting everyone into the same conversation.
- If you feel pressure to move quickly, stop. Urgency is the most reliable warning sign in this entire subject area, and the piece on scams aimed at older homeowners explains why it recurs so often.
When there is no document
If capacity is already gone and nothing was signed, a power of attorney is no longer available. What remains is a court process — a conservatorship, in California terms — in which a judge appoints someone and supervises what they do with the property. It is slower, more public, and more expensive than the document would have been, which is exactly the argument for the document.
It is also not a catastrophe. Families go through it, houses are properly cared for and sometimes properly sold, and the supervision that makes it cumbersome is the same supervision that makes it safe. An attorney is genuinely necessary here rather than merely advisable.
What a real estate professional can and cannot do
Someone in my position can tell you what a transaction will require, flag early that a document's language looks like it needs review, and coordinate patiently with counsel and the title company so the paperwork side does not become the crisis. What nobody in real estate can do is interpret the document for you, judge anyone's capacity, or advise you on whether to sign one. Those are lawyer questions, and it is worth being suspicious of anyone who blurs that line.
It is also worth saying that none of this obliges anyone to do anything with a house. Most of the families who work through the authority question do so and then carry on living exactly as they were, with the paperwork sitting in a drawer against a day that may never come. That is a good outcome, not a wasted afternoon.
A sensible order of operations
If you are the owner: talk to an estate planning attorney while nothing is urgent, name someone you trust, and tell that person where the document lives. A perfect document nobody can find has never helped anyone.
If you are the adult child: ask whether documents exist before you ask what the house is worth. The second question cannot be usefully answered without the first, and asking in that order tends to make the whole conversation easier.
The senior living and housing guide is the map for the wider set of decisions this sits inside, and the aging-in-place guide is the natural next read for anyone whose plan is to stay.

Frequently asked questions
Can I sign for my parent's Claremont house because I am their child?
No. Being family carries no authority over someone else's real property in California. Authority comes from a valid power of attorney signed while the owner had capacity, from a court appointment such as a conservatorship, or from the owner's own signature. Nothing else substitutes for it.
Does a general power of attorney cover real estate?
Not automatically. Many financial powers of attorney include authority over real property, some do not, and some grant it narrowly. Whether a particular document reaches a particular house is a question about that document's exact language, and an attorney should read it rather than anyone assuming.
Why does the title company scrutinize a power of attorney so heavily?
Title insurance is a promise that ownership passed cleanly, and a signature made under a document that did not actually grant the authority is exactly the defect that promise exists to catch. Expect the original document, questions about the principal's language and status, and recording handled properly.
What happens if no power of attorney was ever signed?
Once capacity is gone, a power of attorney can no longer be created. The remaining route is a court-supervised conservatorship, which is slower, more public and more costly than the document would have been. An attorney is genuinely necessary at that point rather than merely advisable.
Does having authority mean an agent should sell the home?
No. An agent under a power of attorney is a fiduciary who must serve the owner's interests and known wishes, and wanting to stay put is a legitimate wish that the agent's job includes protecting. Pressure to act quickly is the clearest warning sign in this subject area.
