Only the following people can LEGALLY officiate a wedding ceremony:
1. Mayor
2. Judge
3. Authorized minister or priest
... not secretary or Vice Mayor... or else you will be creating an irregularity on your marriage even if the Judge or the Mayor's signature is affixed to it... the operative word is OFFICIATE.. meaning, he/she was the one who personally marry the couple...
If you can't get a judge to agree on your wedding date, you can still look for a minister who is authorized to marry... consider also that not all ministers, priests, or pastors are authorized to officiate a wedding...
