Real covenants and servitudes or just servitudes are similar, and in 1986 a symposium discussed the standardization of the law of servitudes, just servitudes, and true covenants.  If time passes and the initial promise of the Confederation is no longer involved in the country, the application can become lax.  A normal contract of sale contains several clearly defined agreements, including the buyer`s promise of payment, the seller`s promise to transfer clear ownership, and the seller`s promise to deliver the good to the buyer in the absence of default.

The exclusionary language was very different….
