Who Has the Authority to Sell a House?

Selling a property on behalf of someone else adds an additional layer of complication to what can already be an arduous undertaking. It is crucial to ensure before you start the process, that you have the correct legal authority to sell a house on behalf of someone else.

  1. When There Is a Power of Attorney

‘Donor’ – the person making the power of attorney

Attorney’ – the person with authority to make decisions

A Property and Financial Affairs power of attorney gives attorneys the authority to make decisions about a donor’s property. This authority extends to selling their home or other property providing this authority hasn’t been specifically excluded in the power of attorney.

Who Has the Authority Under a Power of Attorney?

The power of attorney will need to be checked to see who is appointed as an attorney as this will be the person (or people) that needs to sign any legal paperwork in relation to the sale including estate agent contracts. If there is more than one person named as an attorney, careful consideration must be given to how those attorneys are appointed. A ‘joint’ appointment means that all attorneys will need to sign papers in relation to the sale of the property. A ‘joint and several’ appointment means that only one of the attorneys will need to be a signatory.

To be used, a power of attorney must be registered with the Office of the Public Guardian (OPG). A registered document will bear the official OPG stamp together with the date of registration.

  1. When Someone Loses Mental Capacity

If someone loses mental capacity without having a power of attorney in place, a property and affairs Court of Protection order will be required to sell any property.

 Who has the authority under a Court of Protection order?

The Court of Protection Order will name people (known as deputies) to deal with property and finances. As with a power of attorney, the Order must be read carefully to see whether deputies are appointed on a joint or joint and several basis to confirm how many people are required to sign documents in relation to the sale of property.

It is important to scrutinise the Order thoroughly to ensure deputies do have the specific authority to sell a house as this will not always be the case. Under a power of attorney, this right is a given unless specifically excluded, whereas under a Court of Protection Order, the authority to sell property must be explicitly provided by the Court.

  1. When There Is a Death

When someone dies whilst owning a property in their sole name, the person (or people) named on the Grant of Representation as the personal representatives of the estate will have the authority to sell the house and it will be those people that must sign any legal documents in relation to the sale including contracts with estate agents. The people named on the Grant of Representation may not be the deceased’s family members and may also differ from the people eventually inheriting the sale proceeds of the property.

If someone dies with a valid Will, their personal representatives will be called executors and will be named on a Grant of Probate. If someone dies without a valid Will, their personal representatives will be called administrators and will be named on Letters of Administration. Essentially these documents look very similar.
