Court messed up my name, whats my play?

[Henry17]

1) That there is an error on the letter doesn't mean that there is an error on the ticket. As Otnemem pointed out what matter is what is on the ticket itself.

2) Assuming there is an error on the ticket it is not certain that this is a material error so the ticket might still be valid if the rest of the information is correct. What constitutes a material error is jurisdiction dependent.

3) Even if there is a material error at this point if you are getting 2nd notices and additional fees you have already been convicted. It would have been a lot easier to contest the ticket before a conviction was entered. Now that a conviction has been entered contesting it would be more effort then it is worth.
