Writ of execution and all that and people don't end up collecting.
[...]
I'm in NJ but landlord lives in Atlanta.
People don't collect only if their adversary has no identifiable, attachable assets, or when it costs more to collect than the judgement is worth.
Her living in GA might
potentially make collecting more expensive, but on the other hand, if she really lives there full-time, it also gives her no small incentive to cough up the deposit before it comes to the actual trial, since either she or her attorney and/or witness(es) will have to show up in court in NJ or risk a default judgment against her, either of which will cost her
some amount of money. Since the deposit she owes you isn't that much and even the "cost" of a salaried attorney on her staff (much less one paid by the hour), or personal a roadtrip or air flight from GA to NJ, aren't quite "pocket change", hopefully it'll turn out that she's just a reasonably intelligent scumbag. The sort who hopes the people they try to screw will fume impotently and then go away rather than try to do something practical about it, but who're smart enough not to argue too much or throw money into it when they realize they've guessed wrong in any particular situation...
If you do get a judgment one way or the other, not only can you (at greater expense) pursue collection in GA, or put a lien on her NJ property, but she may well have liquid assets in NJ. (And there are companies that track down other people's assets, not necessarily at great expense.) If nothing else, in the form of the monthly rents being paid on her property. Where did you send
your rent checks? Where were those checks deposited? (Check your cancelled checks, or more likely the images which are probably available online in magnifiable form, as well as printed as small images on your statements.)
As for the rest, is it too much to hope for that you have photos of the empty apartment as you left it? Any sort of documentary evidence of any kind that she did in fact do the walk-through with you (emails, text messages, or saved voicemails setting up the appointment, for example) and/or that she expressed satisfaction with its condition? Every little bit helps...
