The right to own property, to bequeath it to heirs, and to inherit it was established by the Permanent Constitution of 1973 this right was suspended in 1985. Sudan had long had a system of land registration through which an individual, an enterprise, or the government could establish title to a piece of land. Such registration had been extensive in northern Sudan, especially in Al Khartum, Al Awsat, and Ash Shamali provinces. Before 1970 all other land (unregistered) belonged to the state, which held ownership in trust for the people, who had customary rights to it. In 1970 the Unregistered Land Act declared that all waste, forest, and unregistered lands were government land. Before the act's passage, the government had avoided interfering with individual customary rights to unregistered land, and in the late 1980s it again adhered to this policy.

The government owned most of the land used by the modern agricultural sector and leased it to tenants (for example, the Gezira Scheme) or to private entrepreneurs, such as most operators of large-scale mechanized rainfed farming. In the late 1980s, however, the great area of land used for pasture and for subsistence cultivation was communally owned under customary land laws that varied somewhat by location but followed a broadly similar pattern. In agricultural communities, the right to cultivate an area of unused land became vested in the individual who cleared it for use. The rights to such land could be passed on to heirs, but ordinarily the land could not be sold or otherwise disposed of. The right was also retained to land left in fallow, although in Bahr al Ghazal, Aali an Nil, and Al Istiwai there were communities where another individual could claim such land by clearing it.

Among the transhumant (see Glossary) communities of the north, the rights to cultivated land were much the same, but the dominant position of livestock in community activities had introduced certain other communal rights that included common rights to grazing land, the right-of-way to water and grazing land, the right to grass on agricultural land unless the occupier cut and stacked it, and the right to crop residues unless similarly treated. In the western savannas, private ownership of stands of hashab trees could be registered, an exception to the usual government ownership of the forests. But dead wood for domestic fuel and the underlying grass were common property. Water, a matter of greatest importance to stock raisers, was open to all if free standing, but wells that had been dug and the associated drinking troughs were private property and were retained by the digger season after season. In northern Sudan, especially in the western savanna where increasing population and animal numbers have placed pressure on the land, violations of customary laws and conflicts between ethnic groups over land rights have been growing. Resolution of these problems has been attempted by local government agencies but only on a case-by-case basis.
