Some mediators prefer to conduct the framing stage in separate sessions, as they believe it better prepares each of you for the next stage: negotiating. Other mediators favor joint sessions because they believe that hearing your spouse work with the mediator to formulate interests lays a better foundation for the give and take of the negotiation stage. Either way can work, although separate sessions make the mediation cost a little more and take a little longer, because anything important that is said in the separate session will have to be repeated to the other spouse.
All marriages prohibited by law shall be absolutely void, without any decree of dissolution or other legal proceedings, with the following exception. When a person who's husband or wife has been absent for four successive years, without being known to the person to be living during that time, marries during the lifetime of the absent husband or wife, the marriage shall be void only from the time that its nullity is adjudged. If the absentee is declared dead, the subsequent marriage shall not be void.
It is understandable that when people reach agreements together based upon what they think is right and fair, their agreements are much more sustainable going forward than court orders that tell the parties what they must do or not do, pay or give to the other party. In fact, a great advantage of mediating your divorce settlement is that you will make all the decisions together about what is best for you both and for your children as you go forward.
In addition, a finding of irretrievable breakdown must be supported by evidence that either a) the parties have lived separate and apart for a period of not less than 180 days immediately preceding the date of service of the divorce petition; OR b) there is “serious marital discord adversely affecting the attitude of one or both of the parties toward the marriage.” 
In almost all cases, you will be required to attempt some form of alternative dispute resolution. This will typically take the form of "mediation" which is a process in which a neutral third party, typically an attorney trained in mediation, will attempt to assist the parties in reaching their own compromise settlement of some or all issues between the parties. The mediator does not make decisions, but rather facilitates a discussion between the parties (sometimes alone and sometimes with the assistance of counsel) aimed at reaching settlement of your issues. The mediation process is confidential, and if you are not successful in reaching a mediated settlement, the judicial officer will never learn what positions either party took in mediation. As part of the mediation process, the mediator will request both parties provide an accurate summary of income, assets and liabilities. It is recognized that sometimes, one party controls some or all of this information, and skilled mediators attempt to assure that there is a full and fair disclosure of financial information, and a full and fair discussion of the issues.
As a mediator, I have found that custody mediations are frequently transformative. Parties deal with the fact that they'll have an ongoing relationship as parents. And they realize that when it comes to the kids, they can be on the same side. The result? Parties come up with a parenting plan they've jointly agreed on and gain tools to communicate with each other about their children. And research shows that parents who mediate have a better long-term relationship with their children.
Minnesota Divorce and Family Mediation offers skilled guidance on all the important issues surrounding your divorce. The mediation process consists of guided sessions to determine how assets will be divided, discuss budgets and future financial needs, calculate child support and spousal maintenance (when necessary), and develop a parenting plan. Through mediation, couples maintain control over the important life decisions that need to be made during a divorce, while at the same time developing a new foundation for their future relationship with each other. By choosing this gentler approach to divorce, couples are more likely to be able to positively work together in the future; they are less likely to return to court for post-decree issues; and they are more fully prepared to move forward for a better tomorrow.
The vast majority of divorcing spouses - 97% according to some research - resolve all issues without going to trial. More and more individuals are resolving their issues on their own. Attorneys have recognized this, and many seek to support divorcing spouses in this do-it-yourself process. For example, some divorcing spouses will meet with attorneys separately for a consultation, and then attend mediation on their own. This way, each spouse can be well-informed about their options, but still maintain control (and keep the costs down) as they move forward to resolve any outstanding issues.
A divorce can get complicated if the parties have property (real estate, automobiles, vacation property, pensions, jewelry, etc.) or minor children. Usually, the divorce can be done more quickly if the spouses agree on how to divide the property and handle custody and parenting time with the children. Many cases start out with a lot of disputes, but then the parties are able to reach an agreement. Parties often reach agreement after using alternative dispute resolution (ADR) services outside of court. NOTE: If you feel threatened by or unsafe with the other party, you may want to get legal advice or help from an advocate before using ADR.
