question #3 Sahih al-Bukhari 2213, Book 34, Hadith 159 : What conditions nullify the right of preemption in joint ownership according to Islamic teachings?

Allah’s Messenger (ﷺ) gave preemption (to the partner) in every joint property, but if the boundaries of the
property were demarcated or the ways and streets were fixed, then there was no pre-emption.
