one such crucial legal document is the deed of lease, which is the contract that outlines the terms of your lease. this article will explain: a deed of lease is the final document that sets out your lease terms, that both you and your landlord need to sign. a deed of lease may be the final version of an agreement to lease, which is a similar document. the difference is that an agreement to lease may have conditions you need to fulfil before you can move in, whereas the deed of lease is final. while this may be convenient, your legal position is far more secure if you sign and finalise a deed of lease. you may modify this form or use a different one, but it typically covers these clauses (table): will detail the condition of the premises at the start of the lease, with photos and tickboxes detailing whether it is in good or average condition.
