A. The terms and conditions of the tenancy agreement are set by the property owner. Some landlords opt for a flexible lease agreement which requires only a single tenant’s name. However, some landlords prefer a rigid structure which requires every individual over a certain age to sign the agreement. Some of them allow pets and children and some don’t. If you have children and pets or if you are planning to expand your family, be upfront and inform your landlord at the very beginning.
