The rent modification amendment is used when:
- Improvement works carried out by the landlord justify an increase
- Triennial revision of the 9-year lease (between the 9th and 6th month before the end of the three-year period)
- Mutual agreement to adapt rent to market conditions
- Temporary reduction (works affecting enjoyment, commercial gesture)
Annual indexation does not require an amendment — a simple notification suffices.
| Situation | Legal basis | Conditions |
|---|---|---|
| Triennial revision | Art. 7bis Law 20/02/1991 | Request between 9th and 6th month before end of period, justification of new circumstances |
| After works | Art. 8 Law 20/02/1991 | Works > value of 3 years’ rent, max increase 10% |
| Mutual agreement | Common law | Free, at any time, by signed amendment |
