This right is called a guarantee of ownership and applies to both periodic and temporary rental contracts. Their lease agreement then becomes a partial lease 4 and can be followed by another part 4 lease agreement – both described below. The Planning and Development (Housing) and Residential Tenancies Act 2016 extended Part 4 of the lease (property guarantee) from 4 years to 6 years. This applies to all leases from 24 December 2016. If you have a fixed-term lease or lease, you are also subject to the terms of this agreement. This means that you may lose your deposit if you leave before the deadline indicated in the rental agreement, even if you indicate the right amount of termination as described above. There are, however, some exceptions, for example: the remaining tenant is not entitled to a lease of the property.
