One of our customers isnt paying for his fence because his neighbor says the fence is on his propert. I have filed a lien and was thinking of sending this email " We’ve had to file a lien on your property because of non payment. I’ve tried calling multiple times for payment and it’s obvious that you don’t want to settle this because your neighbor threatened to send you a letter. If I don’t hear something from you and since this is a shared fence we’ll look into sending your neighbors a letter of intent also." I know filing the lien on the neighbors is illegal but could i have legal problems by just sending this email as a scare tactic? If I send this email he might pay but I bet he'll write me a bad google review and that could cost me future sales.
