§ 59.1-505.5 – Performance by delegate; subcontract

1. the contract prohibits delegation or subcontracting; or
2. the other party has a substantial interest in having the original promisor perform or control the performance.
b. Delegating or subcontracting performance does not relieve the delegating party of a duty to perform or of liability for breach.
c. An attempted delegation that violates a term prohibiting delegation is not effective.
