How to contest a real estate appraisal in Morocco
Six effective grounds to contest an appraisal report — procedural defect, undocumented comparables, mission overreach, bias. Counter-expertise procedure before Moroccan courts and cassation appeal.
An appraisal report in Morocco can be challenged when it shows a defect of form (designation procedure, summons, adversarial principle) or a defect of substance (methodology, qualification, motivation). Three situations give rise to contestation: judicial expertise ordered by court, private expertise produced by a party, administrative expertise (typically tax authority, OFPPT, ANCFCC).
The six most effective grounds for contestation
Summons defect — CPC article 63: the expert must summon the parties at least 5 clear days before operations by registered letter with acknowledgment. Late, mis-addressed, or omitted summons makes the report challengeable. Civil Cassation ruling no. 61 of 27 February 1981 — constant precedent.
Undocumented or inexistent comparables — a report retaining a value without citing reference transactions, or relying on listings (Mubawab, Avito) instead of closed transactions, is technically challengeable. RICS Red Book Global Standards 2025 doctrine and the Moroccan Real Estate Valuation Charter impose source traceability.
Method unsuited to asset type — using DCF on raw agricultural land, or comparable method on a bespoke factory without DRC cross-check (VPGA 5), constitutes methodological error.
Mission overreach — the expert who rules on legal questions (property qualification, title validity) exits the technical mandate. Precedent: Criminal Cassation ruling 2443/7 of 11 December 1997.
Motivation or adversarial principle defect — CPC articles 63-66.
Conflict of interest or bias — undisclosed personal, professional or financial link between the expert and a party. Leads to recusal then nullity.
Counter-expertise procedure
Moroccan CPC authorises counter-expertise or expertise complement request. The contesting party files a motivated petition with the judge who ordered the initial expertise. The judge may: order a complement to the same mission with the same expert; order a complete counter-expertise by a new panel (often 3 experts for major stakes); reject if grounds are insufficient. Contestation can be supported by an independent private expertise — RICS Red Book report, documented comparables, alternative method argued.
Appeal and cassation remedies
When the trial court has ruled on the basis of a contested expertise, cassation may be grounded on: lack of legal basis (judge failed to respond to expertise contestation arguments); distortion (judge's conclusions contradict the file's pieces); motivation defect (decision insufficiently motivated regarding contestations raised). The civil and administrative chambers of the Moroccan Court of Cassation have produced consolidated case law on the conditions for judicial expertise validity.
Defence strategy: what to produce
Technical memorandum identifying point-by-point the contested report's defects. Independent private expertise compliant with RICS Red Book — traced comparables, clear methodology, photos and measurements, cited sources. Procedure pieces — copies of summons (or proof of their absence), operation minutes, deposited statements and their response. Structured legal argumentation — CPC articles 63-66, applicable case law, doctrine.
When to contest — when to negotiate
Contestation is recommended when the gap between expertise value and real market value exceeds 30%, when a procedural defect is demonstrable, and when financial stakes justify cost and delays (24-36 months between request and final ruling). It is not recommended when the gap is small, when the initial expertise is solidly substantiated, or when a transactional agreement is still possible.

FAQ
Can I contest a private appraisal report?
Yes — by producing an independent counter-appraisal that contradicts the contested report's findings with traceable methodology. The judge then weighs both. For an administrative or judicial appraisal, formal request for counter-expertise to the court that ordered the initial mission is required.
How much does a counter-expertise cost?
An independent RICS Red Book private expertise starts at MAD 3,500 excl. VAT for standard residential assets. Complex assets (industrial, hotel, conflict-rich indivision) may require higher fees. The counter-expertise typically pays for itself when the contested value gap exceeds 30%.
