Does the co-owner have more say than a primary owner?

In most cases, the primary owner has more authority and decision-making power than a co-owner, as they typically hold the majority share or control of the business or property. However, the specific rights and responsibilities of each owner can vary based on the terms outlined in their ownership agreement. If the co-owner has been granted equal decision-making rights, they may have a significant say in certain matters. Ultimately, the balance of power depends on the legal structure and agreements in place.
