You might be able to file a "
Motion to Withdraw or Amend Admissions". You need to go to your local law library and research this to find out if this will apply to your state rules. You also will have to come up with some solid reasons in order fto get the court to rule in your favor. In the little research I've done (you'll see this if you review some of the cases provided in the link I've given you), most judges typica,ly rule against this type of motion but it still may be worth a try. You will have to very carefully think this through. since in the few cases I looked at, they were sginficiantly differently from yours. You will need to file the motion (using proper form for you state) and send court stamped copies to the plaintiff as well as to the court. I've provided a link to some case law and other links regarding this topic for you to get started with. Start with this and then ask questions as needed. Maybe there are others who have some additional ideas for you. This will not be easy.
You must state a reason that you did not file on time. For one thing you are a Pro Se (not out of choice, but out of necessity) and I assume you have never represented yourself in court before and are not familiar at all with court procedure. You went to the court and asked the court clerk and he/she told you that you had 90 days (this is based on what you've stated and I do not doubt you are telling the truth). You will need to attach to your motion a sworn affidavit (under penalty of perjury) stating this. Even though it may be your word against the clerk's, they cannot refute a signed affidavit (I think you can probably find a template for this somewhere in the suijuris download section) and even though the court won'l like (nor the clerk who's involved) the truth is the truth and you shouldn't be penalized if the clerk gave you incorrect information. Make sure that when you present this to the court, that you do it with humility as it may have been unintentional. If the judge is fair, he may just chalk it up as a mis-communication which is quite common with Pro Ses who are in court for the first time. Whatever the case, it is your decision to make in terms of how you proceed.
