Party wall notices.
What makes one valid.

A notice is the document that starts everything. The clock, the rights, and the obligations on both sides. Get the content or the service wrong and it does none of those things: it starts no clock, confers no rights, and has to be done again. A surprising proportion of the notices we are shown are defective.

The checklist

What a valid notice must contain.

There is no prescribed form, which surprises people. What the Act requires is substance, and every item below has to be right.

If you have received a notice and something on this list is missing or wrong, that matters. Send us a photograph of it and we will tell you whether it stands up. There is no charge and no obligation.

Requirements

  • The building owner's name and address. The real owner, not the builder and not the architect. An agent may serve and sign as agent.
  • Every adjoining owner named and served. Joint owners individually, freeholders and leaseholders with over a year unexpired, and each flat where relevant.
  • An accurate description of the works. Enough detail for the recipient to understand what is proposed. "Alterations to the rear" is not enough.
  • The correct sections cited. 1, 2, 6(1) and 6(2) as applicable, and often more than one at once.
  • The correct notice period. Two months for section 2, one month for sections 1 and 6, running from service.
  • The proposed start date, which must be no earlier than the expiry of the notice period.
  • The date of the notice. Undated notices create obvious difficulties over when the clock started.
  • Plans and sections for section 6, showing the depth and position of the proposed excavation. A section 6 notice without them is incomplete.
What we see go wrong

The five defects that come up again and again.

Only one joint owner served

Where a house is owned by a couple, both are adjoining owners and both must be served individually. Serving 'Mr and Mrs Smith' as a single addressee, or serving only one of them, is a defect, and it is the one we see most often.

Section 6 omitted

A notice covering section 2 works to the party wall, silent on foundations being dug within 3 metres and deeper than next door. The section 6 element simply has not been noticed by whoever drafted it.

Works described too vaguely

A description so general that the recipient cannot tell what is actually proposed defeats the purpose of a notice, which exists to inform.

Served by email without consent

Email service is valid only where the recipient has confirmed in writing that they will accept it. Sending a notice by email to someone who has never agreed to that is not good service.

Wrong notice period

One month applied to section 2 works that require two, or a start date earlier than the expiry of the period stated.

Served in the builder's name

The notice belongs to the building owner. A contractor serving in their own name as though they were the owner produces a defective notice.

Defective does not mean you should ignore it

If you are the adjoining owner, the safe course is to take advice quickly rather than to decide for yourself that a notice is invalid and put it in a drawer. If you are wrong, the 14 days runs out anyway. If you are right, that is a conclusion worth having from a surveyor who can say so in writing.

Notice questions

How must a notice be served?

Section 15 allows service in person, by post to the adjoining owner's usual or last known residence or place of business, or, where the owner cannot be traced, by addressing it to 'the owner' and fixing it to a conspicuous part of the premises. Email service is only valid if the recipient has stated in writing that they are willing to accept service that way. Assuming email is fine is a common route to an invalid notice.

Does the notice need to be on a special form?

No prescribed form exists. What matters is content: the building owner's name and address, the property, an accurate description of the proposed works, the sections relied on, the proposed start date, the date of the notice, and, for section 6, plans and sections showing the depth and position of the excavation. A notice on plain paper containing all of that is valid; a glossy template missing any of it is not.

How long is a notice valid for?

Twelve months. Section 3(2) provides that a section 2 notice ceases to have effect if the works are not begun within twelve months of service and prosecuted with due diligence. If your project slips beyond a year, the notice must be served again.

Can a builder or architect serve the notice?

The notice is the building owner's and must be served in their name, though an agent, a surveyor, architect or solicitor, may serve it on their behalf and sign as agent. A notice served in the builder's own name, as though the builder were the owner, is defective.

What if I think the notice I received is invalid?

Do not simply ignore it, because if you are wrong you will have let the 14 days run out. Take advice quickly. If the notice is defective it starts no clock and confers no rights, and your neighbour will have to serve again properly. But that is a conclusion to reach with a surveyor rather than on your own.
