Feudal law in the context of "Lord paramount"

Allod, deriving from Frankish alōd meaning "full ownership" (from al "full, whole" and ōd "property, possession"; Medieval Latin allod or allodium), also known as allodial land or proprietary property, was, in medieval and early modern European feudal law, a form of property ownership where the owner had full and absolute title. The allodial landowner, also known as an allodiary or hereditary lord, had the right to alienate the property, which was almost always land, a city plot, or an estate, and owed no feudal duties to any other person in respect of it.

In feudal law, nulle terre sans seigneur (French for "no land without (a) lord", pronounced [nyl tɛʁ sɑ̃ sɛɲœʁ]) is the principle that one provides services to the sovereign (usually serving in his army) for the right to receive land from the sovereign. Originally a maxim of feudal law, it applies in modern form to paying rates or land tax for land of former feudal or feudal-like origin such as land with modern fee simple title, as opposed to land with allodial or udal title.

In the original French, the expression means "No land without a lord" though the legal sense might be more akin to "no property without a liege" since it was at the basis of the link between the infeodated or feal and his liege, in the feudal system.
