North Dakota Century Code Title 32. Judicial Remedies § 32-03-12. Damages for breach of covenant against encumbrances

The detriment caused by the breach of a covenant against encumbrances in a grant of an estate in real property is deemed to be the amount which has been expended actually by the covenantee in extinguishing either the principal or interest thereof, not exceeding in the former case a proportion of the price paid to the grantor, equivalent to the relative value at the time of the grant of the property affected by the breach as compared with the whole, or, in the latter case, interest on a like amount.
