<prompt> Human: Recently the property management company that owned the home my mother in law rents had all of their homes go into foreclosure. They had paid the security deposit for the home when they signed the initial lease, but now the new owner of the home is demanding that my MIL pay a security deposit as well as pet deposits along with regular rent at the beginning of December, which only gives 11 days to try to save enough for almost 2.5x their normal rent.From what I found during my brief research, it seems that generally the old landlord would be responsible for returning the deposit once the homes are foreclosed and they have no interest in the home anymore, unless the deposits were transferred to the new owner, which nobody seems to know anything about.My MIL is upset enough about this that she wants to move so she wont have to work with the new management company, but moving would require a deposit and rent, which is still too much to come up with in 11 days. I was wondering if anyone here might have suggestions for how she should handle the situation, as I dont know what she can do.Edit: I forgot to type this here but I guess I forgot. The lease actually ends in December, so they are demanding the deposit as a condition of the new lease. The concern is whether they can demand a new deposit even though the old landlord already received it.  <response>: SLU law grad here -- the advice in this thread is good, but if she does get fussed about it and feels she might need legal help, I highly recommend she get in contact with the closest legal clinic. Landlord-tenant disputes are their bread and butter and theyre simple enough that a 2nd or 3rd year student should be able to assist her under the supervision of professors likely at no cost. I know SLU has a sizable law clinic and WashU, Mizzou, and UMKC should as well if any of those are closer. I worked several of these cases in the STL municipal court while working for the judge who handled the landlord-tenant docket and most of these people are counting on their tenants not knowing their rights and not seeking representation when the landlord breaks the law.
