Check unclamping of French commercial rent

To examine unclamping of French commercial rent, first distinguish lease renewal from a rent review during the term. Record the legal basis invoked, alleged changes and evidence of their significance. Comparisons should concern the relevant premises and period. This file organiser does not calculate rental value or automatically validate the increase requested by the landlord.

Which issues should I examine in my file?

  1. Is this a rent review or lease renewal?

    Read this distinction: Rent on renewal and rent revision during the lease are distinct mechanisms; first identify which one is being invoked. Record what your documents establish and what remains uncertain.

  2. Is indexation the same as rental value?

    Read this distinction: Index-based rent capping differs from setting rent at rental value after the cap is disapplied. Record what your documents establish and what remains uncertain.

  3. How can a significant change be documented?

    Read this distinction: A ground based on the premises, permitted use, the parties' obligations or local commercial factors requires specific facts; whether a change exists and is material may be disputed. Record what your documents establish and what remains uncertain.

Which documents make this file useful?

Start by locating these records: Lease, amendments, notice or renewal request and rent history; Plans, condition of the premises and evidence of the alleged changes; Dated and comparable neighbourhood, activity or commercial-factor data. Keep unknown or unavailable details marked as such; a checklist is not proof that a document exists.

What does the worked example demonstrate?

A landlord cites changes in the neighbourhood, but the comparisons concern differently sized premises and another period. Request comparable evidence and connect each claimed change to the stated ground for unclamping. This fictional example demonstrates a preparation method, not the outcome of a real case.

Which mistakes can change the analysis?

Avoid these shortcuts: Applying an index formula before identifying the legal basis and relevant period; Claiming that a local change is sufficient without documenting its significance and connection to rental value.
