No dissolution shall be granted unless (1) One of the parties has resided in this state, or has been a member of the armed services stationed in this state, for not less than 180 days immediately preceding the commencement of the proceeding; or (2) One of the parties has been a domiciliary of this state for not less than 180 days immediately preceding commencement of the proceeding. (Minnesota Statutes - Chapters: 518.07, 518.09)
The date on which earnings (including retirement contributions and other income) becomes separate property again, is the so-called “valuation date.”  The valuation date is the date of the initially scheduled prehearing settlement conference, unless the parties agree to a different date, or the court finds that a different date is fair and equitable.  In my experience, the Court seldom exercises its discretion to use a different date. One situation warranting a different date is where the parties have been separated for years prior to commencement of the divorce, and have been living separately, with separate accounts, insurance, bills, etc., during the separation period.

The number of times you go to court and see a Judge or Referee depends on local court procedures and whether you and your spouse can agree on issues regarding your children, property and other matters. If you do NOT agree, the case usually takes longer to finish. It is a good idea to get legal advice before finalizing an agreement with your spouse.
