So, if he signs the final report written by the expert where is the problem?

I suppose that the expert has calculated all the costs to repair the damages. And if your tenant has signed it well he has to pay or you can deduce the amount from the deposit.

So, since there were no expert and the tenants didn't sign the report you have written yourselve, well it has absolutely no value; registered or not.

Citation :It was taken but not in the presence of the tenant

That is not a problem at all.

The report just need to be signed by the expert. The best it to let it also sign by the landlord and the tenant.

Is it the case?

Je suis pas certain, Grmff, que ce soit valable dans tous les cas.

J'ai rencontré un cas similaire et le juge a considérer que le constat de dégâts locatifs n'avait pas de base suffisante pour entrainer une indemnité compensatoire.
En bref, tout dépend du problème, du Juge de Paix et de l'argumentation des parties !

Il arrive que des états des lieux réalisés sans avoir le caractère contradictoire soit considérés par les juges comme illégaux et donc rejetés, comme une clause de bail reprenant la description détaillée des lieux loués (remplaçant l'ELE) est réputée non écrite.  Reste à avoir d'autres preuves, mais c'est peu évident, du moins pour certains type de dégâts.

Citation :I have send numerous e-mails . Are e-mails considered as formal letters?
What do you mean "formal letter"? What is the use? You can proceed in justice even without "formal letter"!

SMS, mail and other letter can be showed in justice. I already did, and succeeded with sms.

The procedure?

2 possibilities: conciliation or requête en justice de paix.

Conciliation is free. You just write to the judge and ask him to organize the conciliation meeting. Your ex-tenant will be invited with a very formal letter from the tribunal.

Conciliation has no formal way to inforce wathever. If the tenant doesn't comme, nothing happens. If he comes but don't agree, nothing happens. Sometimes, it works. It depends upon the quality of the judge, and the will to reach an agreement.

Requete en justice de paix: cost 40€. You also have to join a "certificat de domicile" (you can get this document at the town hall - service population) Cost: between 0 and 10€

If you don't speak french, there is no possibility: you have to hire a lawyer.

van a écrit :
I had done the "etat des lieu" during the entry WITHOUT the presence of my tenant . Now when she vacated the apartment we did it together and she signed on the exit "etat des lieu". But now she refuses to pay my 1100 euros. What should I do? Will it be possible for me to win the claim if I go legally?

I think that the document signed on exit would be sufficient.
Did you write the amounts due to the owner on the paper, or is it just a state of the damages ?
You would probably win, but you'd better have a signed document by parties, with the exact amounts. Otherwise there may be some discussions
