Power of Attorney vs. Conservatorship When Selling a Home in Washington
Who can sign to sell a Washington home when the owner can no longer sign? In Washington, an agent under a power of attorney covering real property or a court-appointed conservator with court authorization may sign. A power of attorney can end on incapacity unless it says otherwise.
A buyer can be ready, the price can be agreed, and the closing can still stop because nobody with clear authority can sign the deed. Sometimes the document that was meant to prevent that problem stops working at the moment it is needed. That is the snag this article is about.
If you are a spouse or an adult child, you may be looking at a house that needs to sell while the owner cannot take part. The two terms you will hear are power of attorney and conservatorship. They are different tools. One is a document the owner signed earlier. The other is a court order.
A note before you read on. This article is general information, not legal, tax, or financial advice. I am a real estate broker, not an attorney, CPA, or lender, and no attorney has reviewed this article. Each rule in the body links to its source. Where the sources used here do not answer a question, the article says so plainly, and that question becomes one to ask a lawyer, the title company, or DSHS before you act.
The two routes side by side
Here is how the two compare, using what the statutes and court pages say.
| Power of attorney | Conservatorship | |
|---|---|---|
| What it is | A document the owner signed while able | A court appointment of someone to manage money and property |
| Who sets it up | The owner, before the problem | A judge, after a petition, notice, and hearing |
| Selling the home | An agent with general authority over real property may sell it, unless the document says otherwise | The conservator needs court authorization to sell the primary home |
| Where the rule lives | RCW 11.125.270 | RCW 11.130.435 |
Both can exist for the same person. More on that below.
What a power of attorney can do with a house
Under RCW 11.125.270, unless the document says otherwise, language granting general authority over real property authorizes the agent to do things like sell or lease it. The statute is titled “Agent authority, real property.” The wording of the document controls, so the first practical question is simple: what does the document in your hands say about real estate?
The form of the document matters too. RCW 11.125.050 says a power of attorney must be signed and dated by the principal, and the signature must be notarized or witnessed. Witnesses have to meet conditions the statute lists, including not being related to the principal or the agent by blood, marriage, or state registered domestic partnership.
Some actions need more than a general grant. RCW 11.125.240 says an agent may take certain actions, such as making gifts, only if the document clearly grants that authority. Selling a home is a different question from giving it away, and the sources used here do not say how a family should treat the proceeds. Where the cash goes after closing is a question for a lawyer.
The catch: incapacity can end the document
This is the part that is easy to miss. RCW 11.125.040 says that, as written, a power of attorney’s authority ends when the principal becomes incapacitated, unless the document contains specific words showing the authority should continue. The statute gives examples such as “This power of attorney shall not be affected by disability of the principal.” RCW 11.125.020 defines “durable” as not terminated by the principal’s incapacity.
So the wording of the document decides a lot. An older form signed without that language may not do what the family expects. Only someone who has read the actual document can say, so this is a question to bring to a lawyer.
Powers that start later
Some documents are written to take effect only when a stated event happens, such as the owner’s incapacity. RCW 11.125.090 says a power of attorney is effective when signed unless it says otherwise, and it describes who can determine in writing that the triggering event has happened: a person the document names, or, if there is none, a physician or licensed psychologist who has personally examined the principal and is unrelated to the principal or agent by blood or marriage, or a judge or appropriate governmental official.
What proof a title or escrow company wants to see that such a trigger has occurred is not in the statute. The sources used here do not say. That is a question for the title company.
When the owner and agent are spouses
Because many readers are married to the owner, one more rule is worth knowing. RCW 11.125.100 lists events that end an agent’s authority. One of them is the filing of an action for dissolution or annulment of the agent’s marriage or state registered domestic partnership with the principal, or for legal separation, unless the document provides otherwise. If a divorce is in the picture, that is a question to raise with a lawyer before any deed is signed.
What the agent owes the owner
The agent is not free to act for their own benefit. RCW 11.125.140 says an agent must act in good faith and loyally for the principal’s benefit, and must keep a record of receipts, disbursements, and transactions. The statute’s record-keeping duty covers receipts, disbursements, and transactions. Who may ask to see those records, and when, is not covered by the sources used here, and it is a question for a lawyer.
What a conservatorship adds
A conservatorship is a court process. WashingtonLawHelp describes it this way: a judge appoints a conservator to help make decisions about money and property, while a guardian handles health, safety, and self-care. The same page says any interested person can start the court case.
The legal standard is high. Under RCW 11.130.360, for an adult the court must find by clear and convincing evidence that the person cannot manage property or finances, that appointment is necessary to prevent harm or a major loss of property or to obtain funds for needs, and that the person’s needs cannot be met by a protective arrangement or another less restrictive option. The statute also says age, eccentricity, poverty, or a medical diagnosis alone are not enough.
RCW 11.130.365 lists who can petition, including the person themself and a person interested in the person’s estate, financial affairs, or welfare, and what the petition must include, such as less restrictive alternatives that were tried or considered.
Selling the home as a conservator
Here is the sentence that matters for a closing. Under RCW 11.130.435, a conservator must get court authorization before selling, encumbering an interest in, or surrendering a lease to the primary dwelling of the person under conservatorship. For real property sales, the statute also says the conservator needs additional authority from the court about what happens to the proceeds.
The court looks at more than price. The same section says the court considers primarily the decision the person would make if able, along with the person’s prior directions, preferences, and values, financial needs, tax effects, and government benefit eligibility. RCW 11.130.420 adds that notice of a sale of the home goes to the people the court names, and for an adult that includes a spouse, domestic partner, or adult children unless the court orders otherwise for good cause.
How long does it take?
The sources used here do not give a timeline for court approval to sell a home. An older Washington Courts guardianship FAQ page says hearings on a petition are usually held 45 to 60 days after service, and that a court visitor’s final report is due at least 15 days before the hearing. That is about getting a conservator appointed, and the page is a general guide, because court practice and local rules vary. Whether court authorization to sell the home is sought with the original petition or as a later step is not covered by the sources used here. How long it takes is a question for a lawyer or the court clerk.
For a seller, the practical meaning is that the only timing figure in the sources used here is the usual 45 to 60 days after service for a hearing. Anyone facing a hard date, such as a placement deadline, will want to ask a lawyer about timing at the very start.

When both exist
Families sometimes wonder whether a court appointment cancels the document. The statutes answer part of that. RCW 11.125.080 says that if a court appoints a conservator after a power of attorney is signed, the power of attorney is not terminated, the agent becomes accountable to the conservator as well as the principal, and the agent keeps authority unless a court limits, suspends, or ends it. RCW 11.130.435 subsection 4 says a conservator cannot revoke or amend a financial power of attorney, and that the agent’s decisions within their authority take precedence over the conservator’s unless the court orders otherwise. The court can revoke or amend a power of attorney.
WashingtonLawHelp’s page says “You usually don’t need guardianship if you’ve given someone power of attorney,” and adds that a guardian or conservator may still be needed if the power of attorney does not cover certain decisions or other problems arise. Whether that describes your situation is a question for a lawyer.
Where a closing can get stuck
From the real estate side, here are places where this topic can become a snag. This describes how a deal can slow down, not a prediction about any one title company.
| Possible snag | What the sources say |
|---|---|
| No document exists | The sources used here describe a court process, conservatorship, among other options; a lawyer decides what fits |
| The document does not mention real estate | RCW 11.125.270 speaks of authority over real property; the document itself must be read |
| The document ended at incapacity | RCW 11.125.040 says it can, unless it has specific wording |
| A springing power was never triggered on paper | RCW 11.125.090 describes who may determine it in writing |
| The third party will not accept the document | RCW 11.125.200 lists when a person may refuse |
| A conservator is in place | Court authorization is needed before the primary home is sold |
That fifth row deserves a closer look. RCW 11.125.190 says a person who accepts an acknowledged power of attorney in good faith, without actual knowledge that it is void, may rely on it, and may request an agent’s certification under penalty of perjury. RCW 11.125.200 says a person must accept or request a certification or translation within seven business days of presentation, and lists reasons a person is not required to accept, including a good-faith belief that the power is invalid or that the agent lacks authority for the act requested.
The statute says “a person.” The sources used here do not say how those rules play out with a particular title or escrow company, or what that company will want to see on a given file. That is a question to ask the title company early.
Also worth asking: a deed has to be signed and acknowledged. RCW 64.04.020 says a deed must be in writing, signed by the party bound by it, and acknowledged. How that works when an agent signs for the owner is not something the sources used here address.
Your timeline depends on which of these snags applies. A short, plain list of the steps from prep to closing is in how I list and sell a home in Seattle, so you can see where a pause in paperwork would land.
A hypothetical, not a real client
Picture an adult daughter whose father owns a home in Shoreline. He can no longer manage his affairs. She finds a power of attorney in a file cabinet, signed years ago, naming her as agent. Before listing, she wants to know three things: does the document mention real estate, does it say it survives incapacity, and what will the title company ask for?
That is the whole case, and the point is that none of those answers come from the listing side. They come from the document, a lawyer’s reading of it, and the title company. If the answers go the wrong way, the conversation to have with a lawyer may turn to other options, which can include a court process like conservatorship. This is an illustration of questions, not a forecast of how any such file turns out. Once those answers are in, the next unknown is what the house would net, and a free seller report and consultation shows what comparable homes sold for.
If the owner has passed away or Medicaid is involved
Two related situations change the picture. If the owner has died, a power of attorney ends: RCW 11.125.100 lists the principal’s death as an event that terminates it, and the sale then follows a different path, which probate real estate in Washington covers.
If the owner is moving into care, the sale touches other rules, including how Medicaid treats the proceeds. The pillar guide on selling a home in Washington when a spouse needs care goes through that, the specialty page on selling a home when a spouse needs long-term care gives a shorter view, and selling a parent’s home for assisted living or memory care covers the parent-and-child version.
Questions to take to a lawyer, the title company, or DSHS
These are the questions the sources used here leave open, or that depend on your specific documents, so each is worth asking early.
- Does the power of attorney cover real property, and does it say it continues after incapacity?
- If it is a springing power, what written proof of the trigger will the title company accept?
- Will the title company accept this document, what do they require beyond it, and how long do they need?
- If the home is owned jointly and one owner cannot sign, what is needed?
- If the owner is married, is a spouse’s signature needed to sell? The sources used here do not cover this, so it is a question for a lawyer.
- If a conservatorship is needed, how long will court approval take in our county, and what does the court expect for the sale and the proceeds?
- Where should the sale proceeds go, and who decides?
- Does any of this affect long-term care benefits, and if so, how does DSHS see it?
Frequently Asked Questions
Can an adult child sell a parent’s house with a power of attorney in Washington?
If the document names the child as agent and grants general authority over real property, RCW 11.125.270 says that authority includes selling or leasing it, unless the document says otherwise. The wording matters, including whether the document survives the parent’s incapacity. The sources used here do not say what a title company will require, so a lawyer would be the person to read the document, and the title company is worth asking early.
Does a power of attorney still work if the owner develops dementia?
Under RCW 11.125.040, a power of attorney’s authority ends when the principal becomes incapacitated unless the document has wording showing it should continue. A document like that is called durable (RCW 11.125.020). “Incapacity” is defined by an inability to manage affairs because of an impairment, not by a diagnosis name alone. Whether your document has the right words, and whether the owner meets the definition, are questions for a lawyer.
Do I need court approval to sell a home owned by someone under conservatorship?
Under RCW 11.130.435, a conservator needs court authorization before selling the primary dwelling of the person under conservatorship. For real property sales, the conservator also needs additional court authority over the proceeds. How long approval takes is not stated in the sources used here, so ask a lawyer or the court clerk.
What if the title company refuses to accept the power of attorney?
RCW 11.125.200 lists situations where a person is not required to accept one, including a good-faith belief that the power is invalid or the agent lacks authority. It also sets deadlines to accept or ask for a certification. The sources used here do not say how this applies to a particular title company, so the first step is asking what they need and why.
Talk through the real estate side first
If a spouse or parent can no longer sign and you own a home in King County or Snohomish County, I can help with the real estate side: what comparable homes sold for, a timeline for prepping, listing, and closing, and a clear picture of what the home would net after costs. The legal questions go to a lawyer, the title company, or DSHS, and I am glad to build the schedule around their answers.
