My husband and I got married in California. We both reside in Nevada. We’ve lived in Nevada for about 2 1/2 years. Can we just file for divorce in Nv?

Place of marriage is irrelevant.  If you, youir spouse, and your child all live in Nevada, Nevada has jurisdiction over all issues.  See our Divorce page, here, and our Grounds and Jurisdiction page, here, including the articles posted there.  If you have any  additional questions, or the facts are different, call and we should be able to analyze your jurisdiction question in a few minutes.
