It is essential to clearly lay out the terms of the termination and those of its renewal. By law the termination of a contract calls for a minimum notice of 3 months. Some contracts stipulate an automatic renewal but make sure you agree with the implied extended rental period.
All expatriate tenants insist on the insertion of a “Clause Diplomatique” as it allows them to break a contract before its determined end. However this only applies when the tenant is sent back to his/her country of origin by his/her employer. The 3-month termination notice must still be given and paid for.
