Had zlien file a notice of intent to file mechanics lien. Person never paid me so I filed a mechanic's lien in Florence, SC in amount of $915 owed to me in regards to swimming pool service work done. ( didn't includes zlien fee, notary fee or recording fee) I looked on Florence county website and it said lien was valid from 1/1/1984 thru 8/3/2018. I filed lien 7/2/2018. Why did this automatically expire after 30 days? Thank you.
