How do I sue my landlord in Serbia for mold damage and withheld deposit?

Under Serbian law, a landlord can only keep a deposit if they prove you caused the damage, while issues like leaks, damp, and mold are usually their responsibility—especially if you reported them. In this situation, you can typically claim the return of the deposit, statutory default interest, and potentially damages (though the latter are very iffy, and need to be proven, which could prolong the process). Your chances of recovering the deposit and interest are fairly good, while compensation claims are uncertain. If it goes to court, the case would usually take at least 2–3 years and depend heavily on an expert opinion about the cause of the problem. Before suing, it is standard to send a formal demand letter, which sometimes leads to payment without litigation.
