Eden Prairie Divorce & Family Law Lawyer, Minnesota

A mistake by both spouses in a marriage that can serve as grounds for an annulment. For example, if one spouse went into the marriage wanting children while the other did not, they have a misunderstanding that will be judged serious enough for a court to terminate the marriage.

The biological father of a child born to an unmarried couple who has been established as the father either by his admission or by an agreement between him and the child's mother. An acknowledged father must pay child support.

An order from a judge that directs a party to come to court and convince the judge why she shouldn't grant an action proposed by the other side or by the judge on her own (sua sponte). For example, in a divorce, at the request of one parent a judge might issue an order directing the other parent to appear in court on a particular date and time to show cause why the first parent should not be given sole physical custody of the children. Although it would seem that the person receiving an order to show cause is at a procedural disadvantage--she, after all, is the one who is told to come up with a convincing reason why the judge shouldn't order something--both sides normally have an equal chance to convince the judge to rule in their favor.

Differences between spouses that are considered sufficiently severe to make married life together more or less impossible. In a number of states, irreconcilable differences is the accepted ground for a no-fault divorce. As a practical matter, courts seldom, if ever, inquire into what the differences actually are, and routinely grant a divorce as long as the party seeking the divorce says the couple has irreconcilable differences. Compare incompatibility; irremediable breakdown.

The taking of a child from his or her parent with the intent to interfere with that parent's physical custody of the child. This is a crime in most states, even if the taker also has custody rights.

The payment made to a lawyer for legal services. These fees may take several forms: hourly per job or service -- for example, $350 to draft a will contingency (the lawyer collects a percentage of any money she wins for her client and nothing if there is no recovery), or retainer (usually a down payment as part of an hourly or per job fee agreement). Attorney fees must usually be paid by the client who hires a lawyer, though occasionally a law or contract will require the losing party of a lawsuit to pay the winner's court costs and attorney fees. For example, a contract might contain a provision that says the loser of any lawsuit between the parties to the contract will pay the winner's attorney fees. Many laws designed to protect consumers also provide for attorney fees -- for example, most state laws that require landlords to provide habitable housing also specify that a tenant who sues and wins using that law may collect attorney fees. And in family law cases -- divorce, custody and child support -- judges often have the power to order the more affluent spouse to pay the other spouse's attorney fees, even where there is no clear victor.

Any act of inflicting unnecessary emotional or physical pain. Cruelty or mental cruelty is the most frequently used fault ground for divorce because as a practical matter, courts will accept minor wrongs or disagreements as sufficient evidence of cruelty to justify the divorce.

A court procedure that dissolves a marriage and treats it as if it never happened. Annulments are rare since the advent of no-fault divorce but may be obtained in most states for one of the following reasons: misrepresentation, concealment (for example, of an addiction or criminal record), misunderstanding and refusal to consummate the marriage.

The inability of a spouse to engage in sexual intercourse with the other spouse. In some states, physical incapacity is a ground for an annulment or fault divorce, assuming the incapacity was not disclosed to the other spouse before the marriage.
