Selling Property as a Deputy or Trustee

Legal Duties, Risks and How to Get it Right

Property transactions are rarely simple. However, selling property as a Deputy or Trustee introduces an additional layer of legal compliance and risk that many people are not fully aware of.

Whether you are dealing with a Court of Protection property sale, managing trust assets, or purchasing a property on behalf of a protected person, the transaction is legally different from a standard conveyancing matter. Deputies and Trustees are fiduciaries. They are making decisions on behalf of someone else, and the law holds them to a much higher standard.

Having a conveyancing lawyer with specialist experience in acting for Deputies and Trustees can make the transaction significantly smoother, safer and less stressful.

What Are Deputies and Trustees?

Deputies are appointed by the Court of Protection to manage the property and financial affairs of individuals who lack capacity to do so themselves.

Trustees are appointed to manage funds or property under a trust arrangement, often following a Personal Injury award or as part of estate planning.

Both roles can be carried out by professionals or by family members and friends. However, in all cases:

Decisions must be made in the best interests of another person
Conflicts of interest must be avoided
Actions must be capable of withstanding scrutiny

Getting it wrong can expose a Deputy or Trustee to challenge, investigation by the Office of the Public Guardian (OPG), or even personal liability.

This article explains what makes property transactions different in these circumstances, the legal duties that apply, and the practical steps that help Deputies and Trustees complete a sale, purchase or transfer safely.

Why Selling Property as a Deputy or Trustee Is Different

When selling property as a Deputy or Trustee, you are not simply “acting for someone else”. You are acting as a fiduciary.

This means you must:

Act strictly within the scope of your legal authority
Make a documented best interests decision
Avoid actual or perceived conflicts of interest
Keep detailed records and justifications

These duties apply throughout the transaction, including:

Deciding whether to sell or retain the property
Selecting estate agents
Obtaining independent valuations
Negotiating price
Signing contracts and transfer documents in the correct legal capacity

Unlike a personal sale, Deputies and Trustees cannot simply take a commercial view. Every step must be defensible and compliant.

Professional Deputies and Trustees

Many families appoint a professional Deputy or Trustee due to the complexity of the role.

Professional Deputies are monitored by the Office of the Public Guardian and are also accountable to regulators such as the Solicitors Regulation Authority or Financial Conduct Authority, depending on their structure.

Because they act in a paid and regulated capacity, professional Deputies and Trustees are held to a higher standard of care.

Key differences include:

Regulatory Oversight

Professional Deputies are subject to OPG supervision and regulatory audit. Their property transactions must withstand external scrutiny.

Documented Decision Making

Files must be audit ready at all times. This includes:

Independent property valuations
Evidence of market testing
Risk assessments
Best interests reasoning

Conflict of Interest Management

Even the appearance of a conflict, such as selling to a connected party or using preferred suppliers, must be transparently managed.

Higher Expectations of Expertise

Professional Deputies are expected to understand:

Mental Capacity law
Trust law
Conveyancing practice
Safeguarding obligations

Robust Financial Controls

Formal accounting systems and authorisation processes must be followed. Property transactions must align with trust accounting and estate management frameworks.

Lay Deputies and Family Trustees

Family members often take on the role out of care and necessity rather than training.

While the legal duties remain the same, common challenges include:

Emotional decision making when selling a family home
Less formal record keeping
Unintentional conflicts of interest
Limited familiarity with Court of Protection procedures
Practical challenges when purchasing adapted property

Lay Deputies often rely heavily on their conveyancer to ensure authority checks and compliance with OPG requirements are handled correctly.

Deputy Powers to Sell Property and Trustee Authority

Before any conveyancing can begin, your solicitor must confirm that the Deputy or Trustee has the legal authority to proceed.

Deputies

The deputyship order must expressly grant authority to deal with property transactions. This power is not automatically included.

If:

The order does not contain property powers
The sale is contentious
There is a potential conflict of interest

An application to the Court of Protection may be required.

Trustees

Trustee powers derive from:

The trust deed
Statute, including the Trustee Act 2000

Co trustees must act jointly unless the trust instrument states otherwise. The trust deed must not exclude property powers.

Mixed Capacity Co Owners

If one legal owner lacks capacity and the other does not, additional steps may be required and court oversight may become necessary.

A conveyancer experienced in Court of Protection property sales can quickly identify whether further authority is needed.

Demonstrating a Proper Best Interests Decision

For Deputies, the Mental Capacity Act requires a structured best interests decision making process.

Trustees must demonstrate that they acted prudently and in the interests of beneficiaries.

Key safeguards include:

Obtaining independent valuations
Evidence of proper marketing
Considering alternatives such as renting
Assessing whether adaptations are feasible
Recording family views
Clear written reasoning for the final decision

This documentation protects Deputies and Trustees if the OPG or beneficiaries later question the transaction.

Land Registry and Conveyancing Safeguards

There are additional procedural requirements when selling property as a Deputy or Trustee.

Signing Documents in the Correct Legal Capacity

Contracts and transfers must clearly state the capacity in which the Deputy or Trustee signs.

Land Registry Requirements

The Land Registry may require:

Evidence of the deputyship order
Capacity wording in the transfer
Confirmation of trustee authority

Errors can lead to delays or requisitions.

Funds Handling and Accounting

Deputies must account for all monies entering and leaving the protected person’s estate. Trustees must comply with trust accounting rules.

High Risk Situations in Deputy and Trustee Property Sales

Certain scenarios require particular care:

Selling a property where the protected person still lives
Purchasing jointly with family members
A Deputy or Trustee buying the property themselves
Proposed loans from the protected person’s funds
Sales at undervalue
Disputes between co Deputies or Trustees
Older or complex trust structures

In these circumstances, specialist advice is essential.

When Is Court of Protection Approval Required?

A Court of Protection application may be necessary where:

The deputyship order does not include property powers
The property is the protected person’s home
There is disagreement between interested parties
The sale is at undervalue
There is a conflict of interest

Failing to obtain approval where required can invalidate the transaction and expose the Deputy to personal risk.

Why Specialist Conveyancing Advice Matters

Selling property as a Deputy or Trustee is one of the most significant and scrutinised decisions you will make.

A conveyancer with specialist knowledge of:

Capacity law
Trust law
Court of Protection procedure
OPG compliance
Land Registry requirements

can ensure:

Authority is properly interpreted
Best interests reasoning is documented
Conflicts are identified early
Regulatory risk is reduced

This partnership protects both the fiduciary and the person or trust they serve.

Frequently Asked Questions

Can a Deputy sell a property without Court approval?

Only if the deputyship order expressly grants property powers and there is no conflict of interest or dispute. If the order is silent, or the sale is contentious, Court of Protection approval will be required.

Do Trustees need beneficiary consent to sell property?

Not usually, provided the trust deed grants authority and Trustees act in accordance with their fiduciary duties. However, disputes or sales at undervalue may require court involvement.

What happens if a Deputy sells property at undervalue?

Selling at undervalue can expose a Deputy to investigation by the Office of the Public Guardian and potential personal liability. Independent valuations and proper marketing are essential safeguards.

Can a Deputy buy the protected person’s property?

This creates a clear conflict of interest and will almost always require Court of Protection approval.

How long does a Court of Protection property sale take?

If authority is already in place, timelines are similar to standard conveyancing. If an application is required, this can add several months to the transaction.
