You can sell your mother’s house using a power of attorney in the UK, but you must have the appropriate legal authority. You must also follow the correct procedures. If a valid power of attorney specifically allows you to manage and sell her property, you can act on her behalf. Usually, a Lasting Power of Attorney (LPA) for property and financial affairs grants this authority. An Enduring Power of Attorney (EPA) created before 2007 can also grant it. You must officially register the power of attorney with the Office of the Public Guardian. Without registration, you cannot use it for property transactions.
What Is the Quickest Way to Get Power of Attorney?
The fastest way to obtain a Lasting Power of Attorney is by applying online through the official government service. This process typically takes around 8 to 10 weeks if the application is completed correctly and without delays. It involves filling out forms, securing signatures from your mother (the donor), yourself as the attorney, witnesses, and a certificate provider, followed by registration with the Office of the Public Guardian.
Understanding Your Authority to Sell Property with Power of Attorney
To sell your mother’s house, the power of attorney document you hold must explicitly grant you authority over property and financial affairs. A Health and Welfare LPA does not provide this power. Only a Property and Financial Affairs LPA or a registered Enduring Power of Attorney can be used for selling property. Without registration, the power of attorney cannot be used to complete such transactions.
How to Sell a House Using Power of Attorney
- Verify the Scope and Registration of the Power of Attorney
Confirm that your power of attorney includes the authority to sell property and that it is registered with the Office of the Public Guardian. Without registration, you cannot legally act on your mother’s behalf in selling her house. - Prepare the Necessary Documents
You will need a certified copy of the registered power of attorney, the property’s title deeds, transfer forms, property information forms, an Energy Performance Certificate (EPC), and your identification documents. - Engage Estate Agents and Solicitors
Inform the estate agents and solicitors involved that you are acting under a power of attorney. Provide them with certified copies of the POA and proof of your identity to ensure the process is transparent and compliant with legal requirements. - Set a Fair Market Price
Arrange for a professional valuation by a qualified surveyor to ensure the property is priced fairly. This helps protect your mother’s interests and reduces the risk of disputes over the sale price. - Complete the Sale
You can negotiate offers, accept a buyer, sign contracts, and complete the sale. Throughout, you must act in your mother’s best interests, as required by the Mental Capacity Act 2005. Keep detailed records of all decisions and transactions.
Legal and Ethical Responsibilities
As an attorney, you have a legal duty to act in your mother’s best interests. This means securing a fair price for the property, managing the sale proceeds responsibly, and maintaining transparency with family members or other interested parties. Your authority ends if your mother regains mental capacity or passes away.
If your mother lacks mental capacity and you do not have a valid power of attorney, you must apply to the Court of Protection to gain permission to sell the property.
Common Challenges and How to Overcome Them
- Unregistered or Insufficient Power of Attorney: Always ensure the POA is registered and grants property sale powers.
- Need for Legal Support: Work with solicitors or conveyancers experienced in POA property sales to avoid mistakes.
- Mortgage Lender Consent: If the property has a mortgage, the lender’s approval may be necessary before proceeding.
- Staying Within Your Authority: Do not exceed the powers granted by the POA document.
Professional guidance is invaluable to ensure a smooth and lawful sale.

Selling your mother’s house with power of attorney in the UK is entirely feasible. This is true if you have a valid, registered Property and Financial Affairs Lasting Power of Attorney or an Enduring Power of Attorney that includes property sale powers. By confirming your authority, you can proceed confidently. Preparing the property properly is essential. You should also work with estate agents and solicitors. Acting in your mother’s best interests is crucial throughout the process. Following these steps helps you navigate the sale successfully. Always seek professional advice. This ensures compliance with legal obligations and protects everyone’s interests involved.
