A sworn translator needs to be present at the beginning of marriage record procedures when one of the parties does not speak Spanish. That is when you will need to have a civil registry sworn translator. 

It is important for them to be a sworn/certified translator, otherwise the Civil Registry will not allow the process to begin. Sworn interpreters have sworn interpreter ID cards that we must always present when we go to translate at a civil registry office. 

At the beginning of marriage record procedures, for example, sworn translators translate and certify the documents before the official at the civil registry office that the spouses then need to sign and promise to adhere to. Once checked, it will be sent for approval by a judge. If the judge gives their approval, a date can then be set for the wedding.
