Taking or hiding a child, or not returning the child after parenting time, can be a serious crime. Minnesota has a law which makes it a crime to deprive another of their custodial or parental rights. Under this law, you do not have to have a court order giving you custody or parenting time. If the other parent is hiding the child, you may be able to show that you have been deprived of your custodial or parental rights.
Conversely, there is no way to finalize your divorce through mediation alone. Even if you reach a tentative agreement in mediation, this agreement must be formalized in a written stipulation, signed by both parties and their attorneys, and ultimately approved by the Court.  This signed stipulation — not your verbal agreements from mediation sessions — is what becomes the enforceable terms of your divorce, and should be prepared or at least reviewed and revised by your lawyer before you sign.
If there are children of the marriage, each spouse has the right to decide where the children live or go to school, whether they should see a doctor, and can make other arrangements that need to be made. These decisions are left to the parents, as long as the children are not being hurt. If the children are being hurt, other people might become involved —doctors or nurses, school personnel, community workers or the police. If you do not want your spouse to take or visit the children because you are afraid the children will not be returned or will be harmed, you do not have to let the children go. However, if there is not a threat that your spouse will kidnap the children, you should think about the children's best interests and whether it would be good for them to see their other parent. If you are concerned about your spouse's visits, consider getting a custody order. If there are children who were born before the marriage and there has been no adoption or custody order, the mother has sole custody in Minnesota until there is a court order to the contrary.
Effective August 1, 2013, the law in Minnesota allows same sex couples to get married or divorced in this state. To file for divorce in Minnesota, at least one party must be living in Minnesota for at least 180 days before starting the divorce case. A same sex couple may also file for divorce in Minnesota if they got married in Minnesota on or after August 1, 2013, and each party to the marriage now lives in a state that does not allow the dissolution of the parties' same sex marriage. See Minn. Stat. § 518.07, subd. 2.
