In Nevada, a divorce may be granted on one of three grounds, irreconcilable differences; incurable insanity for two years prior to the divorce action, and living separate and apart for at least one year, according to Nevada Revised Statutes 125.010.

Divorce on grounds of irreconcilable differences and living apart for one year or longer may be granted on a “no-fault” basis, meaning no proof of the grounds is required. The spouse filing for divorce on those grounds must simply state that the grounds exist to be granted the divorce.

However, divorce on grounds of incurable insanity must be granted in Nevada on a fault basis and only if the filing spouse can provide the judge with corroborative evidence of the insanity at the time of the filing.
