As per Brandon s answer  But if you re using ASP NET MVC which uses unobtrusive validation  you can add the data-val attribute to the first one  I also like to have labels for each radio button for usability    lt span class  field-validation-valid  data-valmsg-for  color  data-valmsg-replace  true  gt  lt  span gt   lt p gt  lt input type  radio  name  color  id  red  value  R  data-val  true  data-val-required  Please choose one of these options    gt   lt label for  red  gt Red lt  label gt  lt  p gt   lt p gt  lt input type  radio  name  color  id  green  value  G   gt   lt label for  green  gt Green lt  label gt  lt  p gt   lt p gt  lt input type  radio  name  color  id  blue  value  B   gt   lt label for  blue  gt Blue lt  label gt  lt  p gt

I had the same problem  Wound up just writing a custom highlight and unhighlight function for the validator  Adding this to the validaton options should add the error class to the element and its respective label            highlight   function  element  errorClass  validClass                if   element  attr  type       radio                      element form  find  input type radio    each function which                         element form  find  label for     this id        addClass errorClass                         this  addClass errorClass                                     else                     element form  find  label for     element id        addClass errorClass                     element  addClass errorClass                                     unhighlight   function  element  errorClass  validClass                if   element  attr  type       radio                      element form  find  input type radio    each function which                         element form  find  label for     this id        removeClass errorClass                         this  removeClass errorClass                                    else                     element form  find  label for     element id        removeClass errorClass                     element  removeClass errorClass

With newer releases of jquery  1 3  I think   all you have to do is set one of the members of the radio set to be required and jquery will take care of the rest    lt input type  radio  name  myoptions  value  blue  class  required  gt  Blue lt br   gt   lt input type  radio  name  myoptions  value  red  gt  Red lt br   gt   lt input type  radio  name  myoptions  value  green  gt  Green   The above would require at least 1 of the 3 radio options w  the name of  my options  to be selected before proceeding   The label suggestion by Mahes  btw  works wonderfully
