Successfully achieved cancellation of material supplier’s lien on the property of their client, a national homebuilder, based on anti-assignment language in contract. The homebuilder’s contract specifically prohibited a subcontractor from assigning work to a sub-subcontractor without the homebuilder’s specific written approval. Despite this provision, the homebuilder’s subcontractor hired a sub-subcontractor without the homebuilder’s approval, and the sub-subcontractor subsequently failed to pay a material’s supplier for concrete. The supplier liened the property. Relying on the contract’s anti-assignment language, the Forsyth County Superior Court invalidated the supplier’s lien because the homebuilder never approved the sub-subcontractor who contracted for the materials. The Court also sanctioned the supplier $3,300 for discovery abuses.
