If two people are named on a deed can one decide to sell?

When a property is co-owned by two or more people as tenants in common or joint tenants each owner can only sell their own interest in the property. They cannot transfer the interest of the other owners. If three people own a property and one wants to sell, that one can try to find a buyer for their share and that buyer will share the property with the other two owners. However, not a lot of buyers would want to share a property with strangers. Each joint owner has the right to the use and possession of the entire property.

A better solution when one joint owner wants to sell is for the other owner(s) to make them a fair offer and buy them out.
