In today's depressed real estate market, I often encounter the situation where a spouse had a non-marital interest in the marital homestead at the time of marriage; but at the time of divorce, the house is upside down. So the question arises as to whether or not the spouse who formerly had the non-marital interest is entitled to any kind of credit in the overall divorce property settlement.
The length of time to complete a divorce depends upon several things. If both sides reach an agreement or if one spouse never responds to divorce papers, a divorce doesn't take much time. If both sides can't agree, then the judge has to decide. In this case it will take much longer because the court will need to gather information and schedule time in order to make a fair decision. Gathering information might mean having a custody evaluation done or getting financial information.
In all of the states we practice in, both equitable distribution states and community property states, the parties are encouraged to actively participate in, and come to agreement on, the fair division of their marital assets and liabilities. But unless you and your spouse are experts in the financial matters pertaining to divorce, this can be a dangerous path to walk.
Usually the petitioner's attorney calls the petitioner's witnesses first. Each witness is sworn under oath and answers the attorney's questions. Then the other attorney may question the witness. Sometimes the court may ask questions. Sometimes the petitioner's attorney will ask additional questions. When the petitioner's attorney has called all of his or her witnesses, including the petitioner, the attorney tells the court that the petitioner rests his or her case. Sometimes the attorneys will present their argument in writing.
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. 
Typically the SENE will involve both parties, both attorneys, and two court-appointed custody evaluators. Usually three hours is blocked for a session. During the session, each party (and his or her attorney) is given the opportunity to explain what they would like for a custody and parenting time arrangement, and why. Questions from the evaluators are asked and answered. Then there is a break while the evaluators confer. Then the meeting reconvenes and recommendations are given and explained, whereupon the parties discuss settlement.
You’ll also want to gather records for all income sources: paystubs, self-employment profit and loss statements, pension disbursements, social security, alimony and child support payments received. As for expenses, you’ll want to list your recurring expenses as well as ongoing liabilities, so that all mortgage payments, car loans, health insurance costs, food, utilities, student loans, credit card payments, etc. are known.
This booklet explains your rights in a Minnesota divorce and includes information on custody, parenting time, child support, maintenance, abuse, and division of property. This booklet does NOT tell you how to get a divorce without the help of an attorney. Divorce law is complicated and changes often. Each case must be handled differently. Unless your divorce is very simple, it is usually a good idea to have an attorney.
