Punch list, snag list, defect list: one job, three names
Snag list, punch list, defect list and deficiency list all describe the same thing: the register of incomplete or substandard work that has to be cleared before a job is finished. The words change with the country. What changes underneath is the contract mechanism they hang off.

The short answer
They are the same document. If a British site manager hands an American superintendent a snag list, nothing is lost in translation except the word. Both are a numbered register of items, each with a location, a description, a responsible trade and a status, produced near the end of a job and worked down to zero.
The reason it matters at all is search and paperwork. Specifying “punch list” in a contract used in Sydney, or asking a Manchester subcontractor for a deficiency list, creates a small friction every time somebody reads the document.
Where each term is used
| Term | Primary market | Worth knowing |
|---|---|---|
| Snag list | United Kingdom, Ireland | Also snagging list. A snagging survey is the inspection that produces it. |
| Punch list | United States | From the old practice of punching a hole in the margin as each item was signed off. |
| Deficiency list | Canada | Punch list is understood too, and the two are used interchangeably on many jobs. |
| Defect list | Australia, New Zealand | Defects list and defect liability list appear in most standard form contracts. |
A few near neighbours are worth separating out, because they are not synonyms. A defects liability list is the register of items raised after handover rather than before it. A handover report is the whole package given to the client at completion, of which the defect register is one part. A condition report or dilapidations report records the state of an existing building, usually at the start or end of a lease, and has nothing to do with closeout.
Where the process genuinely differs
Two things actually change across markets, and neither of them is the vocabulary.
Who writes the list. In the United States the punch list is typically produced by the architect or the owner’s representative, walked jointly with the general contractor, and issued as a formal instrument. In the United Kingdom and Ireland, snagging is more often run by the main contractor internally first, then by the client or an independent snagging surveyor, and the two lists are reconciled. In Australia the superintendent named in the contract usually holds the pen.
What the list is attached to financially. In the US the punch list is tied to release of retainage. In the UK and Australia the equivalent lever is retention, released in two tranches, half at practical completion and half at the end of the defects liability period. The list is what stands between a contractor and money in every case, which is why arguments about whether an item belongs on it are rarely really about the item.
Completion is the real divide
The concept the list hangs off has different names too, and here the difference is substantive rather than cosmetic.
Substantial completion in American contracts means the work is sufficiently complete that the owner can occupy or use it for its intended purpose. Practical completion in UK and Australian contracts means broadly the same thing, that the works are complete except for minor items that do not prevent use. Both trigger the same consequences: the client takes possession, insurance and risk move, liquidated damages stop running, and the defects or rectification clock starts.
The trap is that neither term is usually defined tightly in the contract, so what counts as “minor” is decided by argument. That is covered in the guide to practical completion, and what happens afterwards is covered in the guide to the defects liability period.
Which word to use in your own documents
Use whatever your contract uses. If the contract is silent, use the term the trades on your site use, because the document has to be actioned by them rather than admired by you.
If you work across markets, the safest neutral heading is defect register or defect report. It is unambiguous everywhere, it does not read as an import from somebody else’s market, and it survives being forwarded.
Whatever you call it, the structure is identical, and getting that structure right is what decides whether items get closed on the first visit. That is covered in how to write a defect report that actually gets fixed.
