Power of Attorney in Property Transactions: When You Need It and How It Works

What Power of Attorney Means in a Property Context

A Power of Attorney (POA) is a legal document in which one person (the donor) grants another person (the attorney) the authority to act on their behalf in specified matters. In property transactions, a validly executed POA allows the attorney to sign contracts, transfer deeds, and take other legally binding steps in place of the donor.

HM Land Registry accepts property transactions executed by attorneys under a POA, but it has strict requirements about the form and content of the document and how it must be evidenced in the transaction.

The Two Main Types Used in Property Transactions

**General Power of Attorney (GPA)**

A General Power of Attorney grants broad powers to the attorney to act in financial and property matters. It is typically used in specific, time-limited situations — most commonly where a property owner is overseas and cannot be physically present to sign documents, or where a party needs to exchange and complete on a very short timeline and cannot arrange a notarised signature in time.

A GPA is only valid while the donor has mental capacity. It does not survive the donor losing capacity (incapacity automatically revokes a GPA unless it is an Enduring Power of Attorney made before October 2007). GPAs are therefore unsuitable for long-term management of another person's property affairs.

**Lasting Power of Attorney (LPA) — Property and Financial Affairs**

An LPA for Property and Financial Affairs is a formal statutory document registered with the Office of the Public Guardian (OPG). Unlike a GPA, an LPA for property and financial affairs can continue to be used even if the donor loses mental capacity (provided it was made and registered before capacity was lost).

LPAs must be registered with the OPG before they can be used. Registration takes 8–20 weeks (depending on current OPG processing times) and costs £82 per LPA. Planning ahead is essential — an LPA cannot be put in place once someone has already lost capacity.

When a Power of Attorney Is Needed in Practice

**Seller living overseas:** A seller living outside the UK who cannot return for exchange or completion commonly executes a GPA in favour of their UK-based solicitor, a family member, or a trusted agent. The POA must typically be executed before a notary in the overseas country and apostilled under the Hague Convention 1961. HMRC and HM Land Registry have specific requirements about the form of overseas POAs.

**Incapacitated seller or buyer:** Where a property owner has lost mental capacity and has no previously registered LPA, the Court of Protection must be approached for a "deputyship order" before any property transaction can proceed. This is a lengthy and expensive process (typically six months to a year or more). It underlines the importance of making an LPA while you still have capacity.

**Elderly owner in care:** Many property transactions involving older owners who have moved into care homes require an existing LPA to be evidenced. Solicitors acting for an attorney must obtain an official copy of the registered LPA from the OPG.

**Developer proxy signings:** Large volume new-build developers occasionally use GPAs to allow a single authorised representative to sign documents on behalf of the developer entity. These are internal corporate arrangements and are less relevant to individual buyers and sellers.

HM Land Registry Requirements

When a property transaction is executed under a POA, the following must be provided to HM Land Registry:

• A certified copy of the POA (or in the case of a registered LPA, an official copy from the OPG)
• Evidence that the POA was in force at the time of the transaction (for a GPA, confirmation that the donor was alive and had capacity)
• In some cases, a statutory declaration by the attorney confirming the above

If a GPA or LPA has been revoked at the time of the transaction, any purported dealing is void. Third parties who deal in good faith with an attorney may have some protection under the Powers of Attorney Act 1971, but the circumstances must be carefully reviewed.

Making an LPA: The Practical Steps

LPAs are made using official forms available from the OPG. The process requires:

1. Completing the prescribed form (LP1F for Property & Financial Affairs)

2. Signing in front of a certificate provider (a person who confirms the donor understands the LPA and is acting freely — must be someone who has known the donor for at least two years or is a professional)

3. Obtaining signature from the attorney(s) and any named people to be notified

4. Registering with the OPG (£82 fee; fee waiver available if the donor earns under £12,000)

The OPG recommends using its online service (My LPA) to guide through the form, though the document must still be physically printed and wet-signed.

A Note on Deputyship

If you are managing the property affairs of someone who has already lost capacity and has no LPA in place, you must apply to the Court of Protection for a property and affairs deputyship order. This gives you authority equivalent to an LPA but comes from a court order rather than a document made by the person themselves. The process is complex; you will need a solicitor experienced in Court of Protection work.

Managing property data for someone in this situation — understanding what assets exist and their current condition — can be streamlined using tools like Property Passport UK, which provides an instant overview of property data from official sources.
