Whether or not a landord is required to return a security deposit evenly between former tenants is best answered under the terms of any written lease or other agreement between the former tenants and former landlord.As such, you need to carefully read the written lease assuming you have one in that its terms and conditions control the obligations owed to you by the former landlord and vice versa in the absence of conflicting state law.The ultimate decision will be up to your landlord as to how much of the security deposit will be returned and if there will be any allocation of the amounts to each former tenant or one single check jointly issued to all.
