Should I write a letter to my ex husbands father letting him know my ex stopped paying child support?

Would any rules be broken? Is this harassment? My ex husband has stopped paying child support, I really would prefer not to go through the courts, as a last resort before I just give up entirely I was thinking of sending his dad a letter letting him know his son has stopped paying and If he could please advise him to do so but I don’t want to get in any legal trouble for it
