What term describes the legal control of land through established government rights?

The term that best describes the legal control of land through established government rights is juridical possession. Juridical possession refers to the formal legal recognition of a person's rights over a property, including the right to use, occupy, and manage the land within the framework of laws established by the government. This concept aligns closely with the idea that the government has the authority to regulate land use, impose property rights, and enforce legal claims concerning land ownership.

Ownership generally refers to the legal right to possess and use property, but it does not necessarily encompass the broader aspect of governmental rights and controls. Encumbrance, on the other hand, pertains to claims or liabilities attached to a property that may affect its value or use. Taxation relates to the government's right to impose taxes on property ownership but is just one component of broader governmental rights over land. Thus, while ownership, encumbrance, and taxation all pertain to aspects of land rights, juridical possession specifically captures the essential relationship involving legal control as expressed through government authority.
