How to stop alimony payments out of my paycheck

I was wondering what the process is to stop alimony payments from being taken out of my paycheck automatically monthly. I have a court order from the judge that states that my alimony payments are to end in October but no one seems to know how to get them stopped. I talked to my Lawyer and he hasn’t ever dealt with this situation. I’ve made several trips to the courthouse and they have no idea how to get them stopped. Can someone please point me in the right direction. Thank you!

Provide your employer with a copy of the court order, that terminates the alimony payments. If they require additional documentation, they will let you know, but that should be the first step.
