Is legal seperation just a good as a divorce?

Well, no. They are very different. Nevada has only one form of divorce - an absolute divorce, with no interlocutory or partial forms, unlike certain other States. In addition to absolute divorce, however, Nevada has a separate statutory allowance for separate maintenance, commonly (if inaccurately) referred to in Nevada as a "legal separation." Such an action is used to determine the temporary possession of real and personal property between spouses, along with their financial responsibilities to one another, and either temporary or permanent custody, visitation, and support of any minor children, without dissolving the marriage. Generally, any subject that may be addressed in a decree of divorce may be addressed in a decree of separate maintenance, except that the marital status continues to exist.
