  • The New Turkish Code of Obligations: Important Changes for Leases of Residential & Business Premises

    For decades, the primary Turkish laws governing leases of residential and business premises have been the Law on Leasing Real Property dated May 27, 1955 (the “Lease Law”) and the Turkish Code of Obligations No. 818 dated April 22, 1926 (the “Obligations Code”). Both of these laws, however, will be repealed and replaced with the new Turkish Code of Obligations No. 6098 dated January 11, 2011 (the “New Obligations Code”), which will enter into force on July 7, 2012.
