Utah Substantial Performance is a legal term used to describe when a contractor has done the majority of the work outlined in the contract. It is a form of breach of contract, as the contractor has not completed all the agreed-upon work. In Utah, if the contractor has done enough work to be considered substantially complete, then they can be compensated for the work they have done. There are two types of Utah Substantial Performance: partial performance and full performance. Partial performance occurs when a contractor has completed some work but not all of it. Full performance occurs when the contractor has completed all the work required in the contract. In both cases, the contractor must provide evidence that they completed the work and that it was done in a satisfactory manner. This evidence can include photos, invoices, and other documents. The court will ultimately decide if the contractor has met the “substantial performance” standard. If so, the contractor will be entitled to payment.
