How do you file a lien? I mowed for my neighbor who moved to charleston, and now she wont pay me, so i quit mowing for her, and now her grass is about 3-4 feet high. Her house has been for sale for a long time. The yard looks terrible, and i sent her an email telling her i would cut it, but she got mad and still wont cut it. I want my money now, So how do i file a lien....Its just 25 dollars, but i want my money.
