Texas courthouse wedding

My boyfriend and I are getting married next week at the court house, we didn't want anyone but us there so I called and asked if we needed to take witnesses because I've hear each person takes one or two witnesses that have to sign. The lady I talked to said we don't need to take witnesses, it could just be us two and of course the judge. Did anyone else get married with just you and your husband or was there anyone else with you at the ceremony? We think it's something really private and we're both super emotional people so we want to just be us two who see that.
