Writ of possession

A writ of possession gives the right to the landlord, but is not a schedule for actual eviction. That is up to the marshal/sheriff.

It is not clear what exactly you have "scheduled", but if it is the actual eviction by the sheriff, there is little you will be able to do. If it just a court date scheduled, you always have the opportunity to pay the back rent and fees to prevent eviction.

A writ of possession is actually given to a landlord. It grants the landlord the right to retrieve possession of his/her property. The only limitation on a landlord executing the writ of possession is the availability of a marshall/sheriff to assist with executing it. The fact that you are trying to "stop" the writ of possession says to me that you are the tenant. Unfortunately for you, that also means you are in a powerless position. Once the landlord receives a judgment of possession, the only control that the tenant has is over when and how he/she leaves - moving themselves out sometime within seven days of the judgment being granted or being removed when the writ is executed.
