My question involves landlord-tenant law in the State of: Indiana
I live in a house with 4 roommates (3 of whom do not like me and 1 who does). The 3 signed the lease, then me and the 1 signed on later. The 3 had paid the security deposit, and the 1 and I just paid the roommates for our portion by paying more for rent for 3 months. After the lease is over, the 3 are staying in the house, but the 1 and I are moving out (2 new roommates are taking our places). The Leasing Company says that they will not pay us our portion of the security deposit and our roommates have to.
The 3 want to give us back 70% of our initial deposit since this is the Leasing Co.'s average. I emailed the LC and they said that 70% is the average because a lot of people trash their houses and get $0 back, plus they clean carpets after every tenant (we do not have carpets). The 1 and I want our full deposit back since our rooms have no damage and there is no way to know that we "deserve" 70%. The 3 are refusing to pay us back our full deposits.
Is there any legal action I can take to get my money back / do I have any legal rights in this situation? How do I handle this?
portion of the lease:
Resident and [Leasing Co.] agree that if this Lease is renewed or extended that the Security Deposit will not be returned until the appropriate time following the expiration of such renewal or extension, unless an additional Security Deposit for the renewal or extension has been paid by Resident to Leasing Co.
(Then it says that the security deposit will be returned to one of the 3 roommates.)
