"The doctrine of unjust enrichment is an equitable concept created to remedy injustices that occur where one person makes a substantial contribution to the property of another person without compensation.
"... unjust enrichment arises when three elements are satisfied: an enrichment; a corresponding deprivation; and an absence of juristic reason for the enrichment. When a claimant is under no obligation contractual, statutory or otherwise to provide the work and services to the recipient, there will be an absence of juristic reasons for the enrichment.
"... personal as well as proprietary remedies are available to remedy unjust enrichment.
