Messenger of Allah 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.  

عَنْ جَابِرٍ ؓ جَعَلَ رَسُولُ اللَّهِ ﷺ الشُّفْعَةَ فِي كُلِّ مَالٍ لَمْ يُقْسَمْ فَإِذَا وَقَعَتِ الْحُدُودُ وَصُرِّفَتِ الطُّرُقُ فَلاَ شُفْعَةَ
