What is a tenancy agreement?
First thing’s first: What exactly is a tenancy agreement? In short, it's what you, the tenant, signs with the landlord to record important bits of information and create a legally binding agreement. Things that will be outlined include the address of the place you’re renting, how much the rent will be, and so on, hopefully stopping any confusion or arguments down the line.
One thing to make sure you're aware of is whether the agreement is for a fixed-term or periodic tenancy. A periodic tenancy has no end date, only finishing whenever the tenant or landlord gives written notice to do so. A fixed-term tenancy, however, lasts for a set amount of time, such as a year. It can't be ended early unless both parties agree, and you should make sure it's the right decision before you sign.
While you can technically move out of home at 16, it is often more difficult to get a landlord to agree to a tenancy agreement until you’re 18. If you are 16 or 17, a landlord will sometimes ask for a parent or guarantor to sign on your behalf.
This is because of complications around forming a legally binding agreement with someone under 18, but once you turn 18 the process becomes a lot easier.
