A legal claim registered against a property or project when a subcontractor hasn't been paid for labour or materials. It prevents the owner from selling or refinancing until the debt is resolved. Filing deadlines are strict, so act quickly if payment is overdue.

For subcontractors, it can erode fixed-price contract margins if bids don't account for escalating costs. Escalation clauses in contracts help protect against unexpected cost increases during long-duration scopes.

A contract where the client reimburses your actual costs and pays an additional agreed percentage or fee on top. Common in complex field projects where scope is hard to define upfront. Subcontractors must track and document all expenses carefully to get paid accurately.
