Unjustified enrichment in relation to contract, tort and property law

The unjustified enrichment law creates an independent source of obligations, which for historic reasons often overlaps with other fields of private law-the law of delict, property law, contract law, and negotiorum gestio. This raises many issues concerning the relationship between enrichment claims and other private law claims. The paper examines the issue whether the enrichment claim has a subsidiary role and is excluded in the event that the creditor disposes of a more specific claim based on contract, tort or ownership. In doing so it analyses the principle of subsidiarity and examines the role of unjustified enrichment in the system of private law. While the discussion mainly focuses on the Slovenian law of unjustified enrichment, it takes into consideration the approaches adopted in selected foreign jurisdictions.
