Q: I borrowed my friends sisters car. While i loaned it I had got into accident she did not have insurance and wants to sue

A: She is suing or can sue for damage to her vehicle. I don't know whether her alleged lying about insurance led you to take the vehicle such that you relied upon representations it was an insured vehicle. That notwithstanding, I don't see the relationship between her lying about insurance coverage and the damage you appear to be responsible for. As relates to the difference between what the shop told you was the cost of fixing the car and what she is suing or going to sue you for, please remember that she or anyone for that matter can sue for whatever amount they think they are owed as long as the court in which they bring the lawsuit permits such. If she is in Small Claims Court she can sue in that court for any amount under $10,000.00. Also, what she sues for is not what she ultimately will collect or be awarded. The amount awarded is going to depend upon the proof she presents and whether the Court considers that credible, fair, reasonable and arising from the conduct she alleges triggered the accident and damages. I did not understand the last part where you indicated she is trying to sue for registration fees due parking tickets. I suppose if her argument is "I would not have to pay the registration but for the accident and damages" she may be able to make a case for such fees. As relates to parking tickets, I am going to assume that the vehicle was not driveable as a result of which it sat on the street or parking lot beyond the permitted time thereby resulting in the issuance of parking tickets. If so, she may very well get the Court to award her those costs if she otherwise would never have left her vehicle to sit beyond the time permitted. Please consult with someone who does Small Claims cases in the area where the lawsuit is going to be filed.
