The basic answer is: Depends on what your agreement says.

If it's a partnership, you probably have a document called "Partnership Agreement." If it's and LLC, it's called "Operating Agreement." The agreement will have procedures for removing partners or members. Sometimes these provisions are harsh, even requiring dissolution of the entity.

(If you do not have a written agreement, then the default rules of state law will apply.)
