I am a real estate staging professional. I help people get their homes ready for sale doing anything from painting, repairing things, project and contractor management, sourcing materials, and on and on. I do whatever it takes to get a home ready for photographs and onto the market. I recently got a home ready doing all of the above and more. It happens to be my sons home. I dont want to drag this story out, but his ex-fiance left him with this fixer upper - he was to use my professional services and do whatever it took to get it to market...we accomplished the goal and completed it this past May 15th (its is sold now and due to close in 2 weeks). She has been contacted over and over and over again about paying her half of the bill which is over 8K. She keeps dragging this out and my son agrees that if i have to, i should file a lien against the house because she will not agree to how she will pay me her half. They are both on mortgage and should only probably break even at the sale...My sons lawyer says any monies should go into another escrow acct and be divvied after the closing...i feel that while she still has a stake in the house is my only leverage at this point..I want to sent a NOI this week (even tho it will be a few days after supposed deadline for IL) and then i want to lien the house...we never wanted it to get this far gone...she was so cooperative until recently. What can I do? should I proceed with NOI or not? Does her obligation stop once the house is sold? It is crunch time now and I am so stressed about this...I have been doing this for years and never ever had trouble getting paid...
