How to recover my loss from cosigner?

[Ting Liu]

I have a rental property with lease expired on June 30th, 2018.  I informed the tenant that I won't renew lease with them more than 30 days left on lease.  Well, the tenant refused to move.  Therefore, I had to file eviction.  There is a good chance that I will win the case.  The real question is how to recover the lost rent during eviction.  The tenant doesn't have much money.  But she has her ex-husband as her cosigner who lives in a different state, makes over 100k a year and owns a house assessed at 350K.  After winning the lawsuit, can I recover my loss of rent from the cosigner? If I can, how to proceed?  Thanks!
