Can some besides a Judge sign a court order? Can the judges’ assistant or secretary sign a court order?

My attorney filed a motion for visitation. We all went before the divorce Judge. I received a court order, but later on, I noticed that the hand signatures were different from previous court order the judge had signed. I did some research on forgery of court orders and came up with 18 USC § 505 - Seals of courts; signatures of judges or court officers. Whoever forges the signature of any judge, register, or other officer of any court of the United States, or of any Territory thereof, or forges or counterfeits the seal of any such court, or knowingly concurs in using any such forged or counterfeit signature or seal, for the purpose of authenticating any proceeding or document, or tenders in evidence any such proceeding or document with a false or counterfeit signature of any such judge, register, or other officer, or a false or counterfeit seal of the court, subscribed or attached thereto, knowing such signature or seal to be false or counterfeit, shall be fined under this title or imprisoned not more than five years, or both." Is anyone besides the Judge allowed to sign a court order? I called the D.O.J. and they were interested in seeing what I had but have not gone down to see them yet. I read it is a 5-year felony. Do Federal laws apply to County Courts? Thanks.
