My question involves landlord-tenant law in the State of: Indiana

Hello~

My husband and I are preparing to sign a lease and move next week. We are moving into an apartment owned by a friend of my father. In order to avoid a credit check the landlord is requiring my father to cosign. (My husband and I have a list of references of landlords but this won't change anything) My concern with this is my father is VERY controlling and before I agree I would like to know his rights. Will he be able to come the apartment on his own? Can he make decisions regarding our apartment? Things of this nature. Thank you in advance.
