The persons mentioned in article L. 2421-6 may, in addition, purely and simply waive their rights.
They are deemed to have waived them in the event of a refusal to acquire or lease or, in the absence of a response, within two months of formal notice being given to them.
Constructions made by persons who have waived their rights are allocated to the municipality without compensation. However, the latter is liable to the holders of the right of enjoyment for the compensation allocated in return for this right.
