I have a copy of the original 1991 lease in my possession and she's been on Section 8 since the first lease.

You should also inform the tenant where their Security Deposit is and what you have done to try and get possession of it.

If you have the 15th in writing and she did not contact to extend and her belongings are gone, you have possession. 

Prejudgement order of possession was entered for both non payment and the pet violation.

If you are not a broker with a IORETA account, you should not be taking any form of EMD in your possession.

Each time, the Tenant was able to come up with enough money to pay for the filing and bring their account to an amount the Owner found to be acceptable prior to possession hear date. 

Dismissed, mediation or judgement of possession issued. 

NOTICE TO QUIT AND DEMAND FOR POSSESSIONI ____________________, landlord of the premises located at, ____________________ in which ______________________ (tenant) now resides requests that as of _________________, (date) you quit the unit and give up peaceable possession thereof.Received: ___________________________ (tenant) on _________________ (date)I certify that I personally delivered this notice to________________ (tenant) on _____________.

We will immediately start over to mitigate the tenant's loss for this responsibility, but they are under contact for for rent and expenses until the day a new tenant takes possession.

So the OP just has to recover possession through eviction.
