Construction

Residential building and handover

From the building file to the keys, with buyers who are not professionals.

Updated on 13/08/2026

Residential building adds an actor other construction does not have: the buyer, who is a private individual, does not read technical documentation, and will dispute the finishes two years later. That changes what has to be proved and how it has to be written.

Important

Certified photos from handover day are what decide an aftersales claim. Without them, telling a construction defect from later damage caused by the buyer is one person's word against the other's.

Frameworks cited

Building regulation and the building file, new-build warranties, and consumer protection rules in dealings with the buyer. What must be handed over and within what periods depends on your case and your region; ask your adviser. What matters here is that all of it is handed over once and you must be able to prove it was.

Watch out

The handover certificate signed by the buyer is also the document that fixes when warranties start running. Having it signed with a certified time avoids the argument about the date, which is the first one to appear.

Worth knowing

Handing over the building file digitally, with a signed receipt, also solves the perennial problem: the buyer who says three years later that they never received it.

Can the buyer sign from a phone?

Yes, and it is usually easiest on handover day.

What if there are two owners?

Both as signers, in parallel.

Does it help with aftersales?

It is what lets you scope what was a defect and what was not, with dates.
