Recourse? What do you mean by "recourse"? Do you mean what are your options?
One option is to do nothing and get a summary judgment against you by default. Not a wise move unless you have no defense to a motion for summary judgment and the moving party does not seek extreme measure from you.
You should file a motion in opposition to the motion for summary judgment, putting forth the facts and the law as to why the moving party is not entitled to the granting of a motion for summary judgment.
A motion for summary judgment is required to clearly show that given the undisputed facts in the case (facts you have admitted to as being true), the petitioner is entitled to a certain remedy in the form of judgment as a matter of law.
So, dispute the facts necessary for them to get summary judgment and dispute the application of the law that they reference as most applicable and appropriate in your case. If you successfully dispute the facts required to get summary judgment and/or you dispute the application of the law that they reference, then their motion for summary judgment will likely fail.
AnswerFortunately for you, all reasonable inferences the court must make will be decided in favor of the non-moving party (you). Keep in mind that summary judgment cannot be obtained or defeated by speculation or conjecture alone; there must be specific, concrete facts that establish the claim.
If you believe that you are entitled to summary judgment, you may file a cross motion for summary judgment, which details why you are entitled to a summary judgment against the other party. In that case, you will be held to the same standard of proof as the person who is requesting summary judgment against you.
