I was subcontracted to build a bathroom in Indiana in a County coroner's office. I haven't been paid and the GC stopped responding to me. Ho owes me $5000 for this and 900 between 2 other overdue balances for him. I have not allowed to retrieve tools and supplies that are mine. It has been two months since I was allowed there.
Give my office a call. 260-782-1712. Sounds like you may have a basis as a sub to file a lien, but you need to likely give preliminary notice. Also, to the extent you have any claims based in tort law, this could be slightly complicated involing the tort claims act which also requires a separate type of notice.
