What it means for the owner
- The measurement covers all work done, including work not in the project or not properly ordered (art. 387.º).
- Without a contract term, it is finished by the 8th day of the following month, on site with the contractor, and put in an auto (art. 388.º n.º 1 and n.º 2).
- The monthly account and the other papers are checked and signed by the contractor, who must state any objection when signing (art. 389.º).
- Errors found later are corrected in the next auto if both sides agree (art. 390.º).
