its super easy, just a little on the expensive side I think.
1. print out the name change petition and fill it out
2. get it notarized
3. take it to the clerk of court/family law and pay the fee
4. make sure you have fdle (federal department of law enforcement) clearance aka having finger printing done (around $50)
5. Go to your assigned court date and answer the few questions the judge asks
