Was China not a country prior to 1971, because Taiwan had the Chinese seat in the UN (it meets the international observers standard(?)) and the entirety of China was “disputed”?
As for recognized authority, isn’t it the case that for certain areas of Israel (e.g. certain areas within the 1948 UN partition plan, or 1967 borders) it meets the test you laid out? I.e. people living there agree that the Israeli government is the one that they identify with and international observers agree to recognize the Israeli government’s control over those areas? In that case, Israel would be a country with some disputed borders (I.e. everywhere outside that area with recognized authority).
I feel like you had additional context to this question that you meant to add, but just totally forgot.
As it stands, yes of course. If your house in condemned or otherwise subject to eminent domain, if your house is seized to pay creditors for non-mortgage debt (in some states), if somebody else has superior title to your home and you aren’t protected by being a bonafide purchaser, etc.
