We are a construction company and we build swimming pools. We installed a slide that the homeowner chose. He was not happy with it, said it was too fast and dangerous. We consulted with the supplier of the slide and made adjustments by shortening the length of the slide at the top so it would not be so fast. The homeowner refuses to test it because now the weather is too cold. He will not pay the final balance due on the job. We filed a mechanics lien and now would like to move to the next step but can not find out how to file the lien of intent to foreclose.
