If there is a chance your spouse may seek an Order for Protection or Harassment Restraining Order against you — whether legitimately or fraudulently — it is important to have a plan in case you are suddenly served with one and are barred from your home, with no court hearing set for two weeks. If that happens, do you have a place to stay? Cash and important documents? A spare change of clothing?
The big warning I have is this: years ago, when the program started, the idea was that the evaluators would give their opinion of how they would likely decide the case in a full-blown custody evaluation, based on the facts learned in the SENE. This honest appraisal of how a months-long custody evaluation would likely turn out is what helped parties to settle their cases.
In reality, every divorce requires both formal legal procedures as well as some kind of settlement negotiations. In Minnesota, even if you prefer to litigate and leave every decision up to the judge, the rules require that before the Court will decide your case, parties must attempt resolution through some form of Alternative Dispute Resolution, of which mediation is still the most common.

Like all states, Minnesota requires both parents to support their children, even after a divorce. The amount of child support depends primarily on each parent's income and other resources, and how much time each parent spends with the children. In addition, sometimes the courts will "impute" income to a parent who has the capacity to earn more than he or she actually is earning. To learn more about child support, see Nolo's Child Support area.
Unless your lawyer thinks it's important that you be represented, try the first session without your attorney. (If your spouse is insisting on having an attorney present, you'll want to do the same.) If you're not represented, but you've asked a lawyer to be your consulting attorney just for purposes of mediation, then you'll likely attend the first mediation session on your own. Either way, if you go by yourself and then you find that you can't state your position clearly or stand up for yourself alone, then consider bringing your lawyer to later sessions.
A Motion is a paper asking the Judge or Referee to decide an issue in a case. In a divorce matter, a Motion for Temporary Relief allows you to ask the court to issue a temporary order for child custody, child support, spousal support, and certain property issues. The Temporary Order allows you to get needed financial support while your case is pending in court. The Temporary order will expire when the final divorce decree is signed by the Judge and "entered" by court administration.
