Legal Question in Real Estate Law in Minnesota

Re: Unjust Enrichment

here is a quote from a Minnesota case:

In order to establish a claim of unjust enrichment, the claimant must show that another party knowingly received something of value to which he was not entitled and that the circumstances are such that it would be unjust for that person to retain the benefit.� ServiceMaster of St. Cloud v. GAB Bus. Servs., Inc., 544 N.W.2d 302, 306 (Minn. 1996).
