Mispelling a name would not require refiling. At most, the plaintiff would have to--and would be allowed to--amend his or her complaint to correct the mispelling.If you did not do the damage, you can fight the claim, by presenting your own evidence and testimony that you did not do this; then the court will decide who--you or the plaintiff--is more credible. Or you can try to settle for something you are willing to pay, so as to avoid litigation and its attendent costs and uncertainties.
