I was on a lease with 2 other people (one of them moved in their girlfriend and dog), I had a family emergency out of state and for 2 days was harassed by my roommates. They threatened to throw my stuff in the yard if I didn't come and get it. I was in the reserves at the time, and had already went to the manager about moving out. I showed my military orders and was told it was no problem (I ended up not having to transfer due to pregnancy, and got a new apartment) . I moved out the last day of August, and 3 days later my ex roommates posted a picture of them drawing on the walls with permanent markers, holes in the walls. I showed the manager so she would know I was not apart of the destruction. She gave them a 3 day evict, and now the apartment manager has put me as responsible for all the damages done. The ex roommate went in and told them they and their friends were responsible for all damages, and the manager will not remove me from the lawsuit. She did not remove me like she said prior to me taking the pictures in. She thanked me for the information.. I checked my credit report and it has me as Responsibility: Individual for $4323.00. How can I fight this? I did not do any damage to the apartment. When I left it was in good condition.

If you were named in the lease you are responsible as much as the other roommates. When you get to court you can try to convince the judge that the others did the damage but chances are slim you will not be held equally responsible.

OP, as one of the lessees, is jointly and severally liable with the other lessees for the damage, without regard to who actually caused it. This liability is implied (if not explicit) in the lease. OP could cross-claim against the others, but collecting a judgment is often harder than getting one.

Was there a damage deposit?

Do you have any documentation that you moved out and were released from the lease? If you have such documentation and can show the damage was done after that date, you can file a motion with the court where the suit was filed to remove you from the suit. Without such documentation then you were still considered a lessee and liable for the damages.
