The window between substantial completion and keys handover is the moment of maximum leverage. After escritura, the buyer loses contractual position and depends entirely on warranty enforcement.
CPCV negotiation
Setup · plan ahead
Insert the inspection clause. The Contrato Promessa de Compra e Venda is where the right to an independent pre-handover inspection should be written in, along with retention terms and a defect remediation window. See the pre-CPCV inspection guide.
After substantial completion, before keys handover
Best window
Maximum leverage. The unit is finished, commissioned, and ready. The developer wants the handover signed and the final payment released. Defects raised here are negotiated under the contract, not under warranty.
Leverage
Within 30 days of keys handover
Second-best window
Recoverable. Most finish, MEP, and acoustic defects become visible during first occupation. Documented in writing and sent by registered post or email with read receipt within 30 days, they remain warranty claims under DL 84/2021 with full remedy rights and a strong pre-existing defect presumption.
Leverage
At the escritura table only
Too late
Verbal promises only. By this point payment is structured, the deed is being signed, and the developer has moved to the next project. Defects raised here get verbal commitments, not contractual fixes. The buyer loses leverage at the moment of signing.
Leverage
Six months or more after handover
Warranty path only
Warranty enforcement, not negotiation. The buyer still has 5 to 10 years of warranty under DL 84/2021. The path runs through written denúncia, repair request, and the 3-year court action limit. Recovery depends on the developer's solvency and willingness to act.
Leverage
The single rule
Book the snagging inspection after the developer's internal quality check completes and before the formal handover meeting. This is the only window where the buyer holds the final payment, the unit is finished, and the developer needs the signature to close the deal.
