Can a Florida divorce atty. Repersent me in a Nevada anlument that my husband filed or do i need to hire a attorney from Nevada u

Short answer:  no.  Every state requires the lawyers appearing in its courts to be admitted to practice there, and it is unlikely that your Florida lawyer has a Nevada license.  But you could ask that lawyer.  There is also something call "pro hac vice" allowing a lawyer to step into another state for just one case, but it is usually not cost effective to have a lawyer in one state attempt to navigate the courts of some other state.  For background as to annulment, see http://willicklawgroup.com/annulment/.
