My wife and I have decided that our marriage was rushed and it would be a good idea to go through an annulment. We were wondering if we had grounds?

You do not supply enough information -- including where and when the wedding was, and what you have done since then.  For the applicable rules for such actions, see the materials posted at: http://willicklawgroup.com/annulment/ http://willicklawgroup.com/uncontested-annulment/ Consider a consultation with a family law specialist to examine all of your options.  If you are sure you know what you are doing, and want to do it yourself, a full form set with explanations is posted at the Clark County family court self help center website.  See http://www.familylawselfhelpcenter.org/.
