Acknowledging that the original OP refers to the US and UK it might be interesting to note an article in the German Constitution that deals with property rights:

Article 14 [Property, inheritance, expropriation]

(1) Property and the right of inheritance shall be guaranteed. Their content and limits shall be defined by the laws.

(2) Property entails obligations. Its use shall also serve the public good.

(3) Expropriation shall only be permissible for the public good. It may only be ordered by or pursuant to a law that determines the nature and extent of compensation. Such compensation shall be determined by establishing an equitable balance between the public interest and the interests of those affected. In case of dispute respecting the amount of compensation, recourse may be had to the ordinary courts.
