Under no circumstances may the periods provided for in article L. 412-3 be less than one month or more than one year. In setting these deadlines, account is taken of the good or bad will shown by the occupant in fulfilling his obligations, the respective situations of the owner and the occupant, particularly with regard to age, state of health, status as a war casualty, the family or financial situation of each of them, atmospheric circumstances, as well as the steps that the occupant proves he has taken with a view to being rehoused. Account is also taken of the right to decent, independent housing, the time required for appeals under the terms of articles L. 441-2-3 and L. 441-2-3-1 of the French Construction and Housing Code, and the foreseeable time required to rehouse those concerned.
