It will happen that your default is taken, meaning you already lost. It may be that the default has become a judgment, that a writ of possession has already been issued, and that the Sheriff has posted a notice to vacate, giving you only a few days. This can happen because you weren't served with the summons and complaint, because the clerk erroneously entered your default, because you missed a deadline, or several other reasons.
The situation is desperate, but not incurable. You can un-lose, stop the lockout, and put the case back on track, but it isn't cheap.
This package provides the combination of the ex parte stay [to stop the lockout] and either a motion for relief from default or to vacate the erroneous default [un-lose]. The motion for relief is when it was not the clerk's fault and the motion to vacate is when it is.
If you are filing a motion for relief from default, it will usually require including the papers you would have filed, like a motion to quash or answer, which will be paid for and provided separately from this..
