Is the Request for Notice of Commencement part of the Lien process. I noticed it is not an option in your process. I was taught it was the first step and necessary in filing lien paperwork.
In Ohio, Notices of Commencement are recorded with the Recorder's Office in the county where the project is located. R.C. 1311.04(D) requires the owner of the project to send you a copy of the notice of commencement within 10 days after receiving a written request, but ordinarily it is easier to simply request a copy from the general contractor or look it up yourself through the county recorder.
The notice of commencement is not necessary for your lien paperwork. However, if a notice of commencement was recorded, then you, as a material supplier, were obligated to supply a notice of furnishing to the owner. If you did not serve the notice of furnishing, you should contact an attorney as you may no longer have lien rights (or you may be able to salvage some lien rights). If you no longer have lien rights, your only avenue for collection of amounts owed would be through the party you contracted with, through a breach of contract action.
