Roommates on a lease together evict one of the tenants

[Calla Gruss]

Three individuals signed an 18 month lease for my fiancé’s house. Two of the parties have decided to evict the third person because of multiple personal differences. They have changed the access code to the home and the third person does not have the ability to get into the house and has not retrieved their personal belongings. I believe this is a civil matter between the three individuals but I have questions as to how to proceed as a landlord.

1. Am I obligated to return the evicted persons deposit at this time?

2. Do I need to get a new lease signed for just the two remaining tenants.

3. Are the two remaining parties obligated to pay the full rent or just a third of the rent each? ( currently each party pays their part to me individually)

4. What is my role, if any, in trying to help the evicted person to get their things? ( can I allow access to the individuals for the purpose of collecting his things without permission from the other two tenants?)
