A mispelling does not invalidate a complaint or other legal documents so long as it is still clear who the person is. Only if a genuine issue exists as to who was named in the complaint would there be grounds to dismiss it.If the person who signed now is a co-owner of the property, a managing agent of the property, or an employee of the property owner or the managing agent, it is valid.A correction in the case number will not throw out the case.From what you write, this matter may go forward.
