Ending Rental Agreement/Lease

[Jessica Flack]

Anyone had a situation like this that could offer advice or direction?

I was going to give my apartment to a person that could move in on Oct 2nd, but another applicant wanted the apartment really bad and even though she can't move in until the 12th, she agreed to start the lease on the 2nd in order to secure the place.

She later called me and said her husband was taking issue with it. She had signed the lease already, but her husband was wanting it to start when she would be moving in on the 12th (she is a traveling nurse, so it is only her moving in). I explained to her what we had already discussed, that if she wanted the apartment, the lease would have to start on the 2nd or I would give it to the other person that could move in then. She agreed. I talked to her about my fear that her husband would cause problems and she assured me it would be fine.

Fast forward to now, she has not paid the rent. She did pay the security deposit. I am not sure what to do now since she has not moved in yet. I know the process if she was living there, but since she isn't what is the legal way to go about this? I just told her she would not be able to move in until she had paid the balance and gave me verification that the utilities were in her name. But can I do that since the lease started on the 2nd and technically she would have been moved in already? Of course I would have required those things then as well. Can I end the lease agreement since she hasn't moved in yet?

The rental is in Wyoming. She lives out of state. 

Thanks!
