Our Rent Now users can add their own custom clauses and collect signatures digitally as part of our entire rental process. If you intend to use the agreement, also check out the rental guide. If your rental agreement began or was renewed on or after October 1, 2015, your landlord must also provide you with an updated copy of the guide for rent. Without a written agreement, you can`t even prove the amount of the tenant`s rent and you can get caught. A lease can be either for a set period of time, which means it ends on a given date, or it can be periodic, meaning it runs from week to week or month to month. To start your rental on a solid legal basis, you need an up-to-date contract signed by all parties: renter, tenant and guarantor. Most leases in the UK are Tenancies (AST). A standard rental agreement for use in the private rental sector, in which a short-term rental contract is concluded, and accompanying advice.
