The State of Minnesota is a no-fault divorce state where either spouse can request a divorce without having any proof of fault.
Since Minnesota is a “no fault” state, the fact that your spouse committed adultery does not affect the property division in your divorce.
All assets and debts that were acquired during your marriage are considered marital property, regardless of the titling of the property. Marital property in Minnesota is divided “equitably,” which does not necessarily mean 50-50.
Assets you have acquired before your marriage is called Non-marital Property. Minnesota Law may protect those assets if you can appropriately trace the claim.
