Start with the project address, the identity of the party that hired you, the written agreement, invoices, and records of work or delivery. Keep notices and communications about payment or disputed charges as well. Our attorneys review the available records and discuss potential next steps. For an appropriate private-project matter, that may include preparing, filing, and pursuing a mechanic's lien. Public-project accounts may involve payment-bond claims instead. The applicable requirements and timing need individual review. Avoid waiting for a general deadline based on another project or assuming that a request for payment is sufficient to preserve a claim.
