Whether the planning work was to be remunerated under the contract of enterprise
Solution extraite
The architect failed to prove that remuneration had been agreed; the respondents rebutted the factual presumption of onerousness.
Motifs extraits
For a planning contract, payment must be agreed. An extensive professional preliminary study only creates a rebuttable factual presumption of compensation. The draft letter of 19 November 2001 showed the owners considered the preliminary work to be 'at risk' and without compensation unless the project proceeded and the architect mandate was later granted.
