A rent deposit deed where the deposit is held by the Landlord on trust for the Tenant, subject to the terms of the rent deposit deed.
This standard document assumes that both the Landlord and the Tenant are both corporate entities and that the rent deposit deed is supplemental to a "new" lease for the purposes of the Landlord and Tenant (Covenants) Act 1995. You may also wish to discuss this document with your private client department as there are tax and trust issues (in addition to those mentioned) on which you may need to obtain specialist trust advice.
