How do you have a birth certificate corrected beause of a misspelled last name?
If it is a simple misspelling, such as "Smiht" instead of
"Smith," (two letters accidently transposed), you can usually have
it corrected by the following: 1) Obtain another legal document,
such as a marriage certificate, or passport, that bears the correct
spelling. 2) Take it to the office of vital statistics that issued
your misspelled birth certificate. 3) They should issue a new birth
certificate for you. In some States, the new certificate will
indicate it was amended on the document itself. In other States,
there is no indication. If the office that issued the birth
certificate will still not correct it, there is another option:
Present an "Affidavit to Amend a Record" to the office that
issued the document itself. You can obtain the Affidavit through
your local county clerk's office or via an attorney.
