Questions about decision making in a partnership?

[Rob Hayes]

Hello all, I'm curious as to how decision makings are handled in a equal partnership? One example would be if a water line rupture & a contractor gives two quotes; one quote to repair ($225), one quote to replace ($750). How are these binary decisions handled in a partnership especially when it involves using funds for a repair vs replace scenario? Also how are tenant management handled such as keeping vs replacing or which tenant to choose during lease signing? I'm curious as to how this could be structured & maybe backed in some type of written agreement. Thanks
