Can My Neighbour Force Me to Pay for Half of a New Boundary Wall?
Generally, no. Under the Act, a person building a new wall wholly on their own land or on the line of junction is usually the building owner and pays for it. Sharing costs normally arises only by agreement or where you ask for or benefit from extra work. Deeds and specific facts can change this.

- Ask the neighbour for their proposal in writing, including the position of the wall.
- Check whether they have served a party wall notice.
- Look at your title deeds and plan for any boundary or fencing obligations.
- Do not agree to share costs verbally.
- Speak to a party wall surveyor about whether the Act applies.
- If you do agree to share, put the terms in a signed written agreement.
What the Act says
Section 1 deals with a new wall built on the line of junction. The person doing the work is the building owner and normally bears the cost. The neighbour does not have to pay merely because a wall is being built.
A wall built entirely on the builder's own land is a different situation. It may fall outside the Act, and your only concern may be that it does not encroach.
When sharing might apply
Costs can be shared if both owners agree. They might also arise where you ask for extra work for your benefit, for example a taller or stronger wall. The award, or a separate agreement, decides the split.
If the wall replaces an existing shared one and you use it, the position can be less clear. Get advice.
Deeds and fences
Some title deeds place fencing duties on one owner, or on both. These are separate from the Act. Ordinary timber fences are not party fence walls under the Act, so common law and your deeds decide who is responsible.
If you feel pressured
You do not have to agree on the spot. Ask for the notice, the plans and a quote. If the neighbour refuses to go through the process, a surveyor can explain your rights in plain terms.
Frequently asked questions
Do I have to contribute to a fence?
Not under the Act, which does not cover ordinary timber fences. Check your title deeds.
Can the neighbour take me to court for the cost?
They can try, but they would need a legal basis. Take advice before responding.
Who owns the wall once built?
That depends on where it stands and what was agreed. A written agreement avoids doubt.
What if I want the wall too?
Agree the cost split in writing and consider having it recorded in the award.
