What to check
Use these prompts with the responsible project team. Ticking a box does not certify compliance.
You can tick these prompts while reviewing the project.
Keep these records
- Scope drawings, ownership enquiries and copies of served notices.
- Written responses, surveyor appointments and any party-wall award.
- Condition records, agreed protective measures and change correspondence.
Common mistakes
- Assuming an approved planning application is a substitute for a Party Wall notice.
- Assuming an informal chat with a neighbour resolves all owners' rights or an ensuing statutory dispute.
When to get specialist help
Consult a suitably experienced party-wall surveyor or legal adviser before notifiable work, contested access or unresolved disputes; do not infer foundation depths from appearances.
Scope and edition

Use the official source to check the current text, amendments not yet incorporated, commencement and project-specific transition. A published future edition is not automatically the rule applying to your work.

About this library
Independent, plain-English reference notes by Saeed Azarshab. The library covers the 42 subjects listed here; it is not every law affecting construction, an official government publication or a project-specific compliance decision. Building Regulations, Approved Documents, workplace safety duties and planning permissions have different roles.
Editorial source review: . Check the current official text, commencement dates, outstanding amendments and transitional arrangements before relying on a requirement. Publication date is not necessarily the date a rule applies. A relevant competent professional or authority must resolve project-specific questions.
