Interesting look at where boundary laws may have their roots. Maybe the oldest law on Estoppel ?

The earliest of the known codes, the Laws of Ur-Namma, provides that a farmer who violates the "rights" of another by growing a crop on his field?ÿforfeits all expenses. A number of cuneiform codes from northern Mesopotamia deal explicitly with encroachments. Under the Middle Assyrian Laws, a bad-faith encroacher has to forfeit his improvements to the land's owner, but one who improves another's land while its owner looks on without objection is entitled to keep the improved land if he compensates the owner with equivalent land.
Love it.
More proof of an error on the CST exam. The Babylonians had surveying before the Egyptians.
