We performed work on a church in December and the GC has been dragging their feet on payment. We had some re-work which we completed in February and March which is part of the reason payment has been slow, however I need to motivate them to pay us. I mentioned the possibility of filing a lien, and the project manager said "the owner has a performance a payment bond on the project which will prevent the lien from being attached to the property title." What are my options? Thank you
