I have been renting an apartment, and my landlord has passed away. His heirs want to sell the property. What happens to my lease?

The lease continues with the heirs (Article 724 of the Civil Code). If they want to sell the property unoccupied, they must give notice within the timeframes set by Article 15 of Law No. 89-462 of 6 July 1989. Otherwise, the property can be sold with the tenant in place.
