The concept of deprivation and enrichment are extremely broad. Deprivation refers to any loss of money or money's worth in the form of contribution while A is enriched if B contributes to the acquisition of assets in A's name. The causal connection between enrichment and deprivation must be "substantial and direct". The absence of juristic reason is satisfied if a Plaintiff establishes a reason why the benefit ought not be retained, or if the Defendant demonstrates a convincing argument in favour of retention of the property. Remedy for unjust enrichment is frequently an imposition of constructive trust over the property unjustly retained.
