Mercier Divorce & Family Law Lawyer, Quebec

A document that provides proof of a marriage, typically issued to the newlyweds a few weeks after they file for the certificate in a county office. Most states require both spouses, the person who officiated the marriage and one or two witnesses to sign the marriage certificate; often this is done just after the ceremony.

Any divorce in which the spouse who wants to split up does not have to accuse the other of wrongdoing, but can simply state that the couple no longer gets along. Until no-fault divorce arrived in the 1970s, the only way a person could get a divorce was to prove that the other spouse was at fault for the marriage not working. No-fault divorces are usually granted for reasons such as incompatibility, irreconcilable differences, or irretrievable or irremediable breakdown of the marriage. Also, some states allow incurable insanity as a basis for a no-fault divorce. Compare fault divorce.

The legal authority to make decisions affecting a child's interests (legal custody) and the responsibility of taking care of the child (physical custody). When parents separate or divorce, one of the hardest decisions they have to make is which parent will have custody. The most common arrangement is for one parent to have custody (both physical and legal) while the other parent has a right of visitation. But it is not uncommon for the parents to share legal custody, even though one parent has physical custody. The most uncommon arrangement is for the parents to share both legal and physical custody.

In most states, any person under 18 years of age. All minors must be under the care of a competent adult (parent or guardian) unless they are 'emancipated'--in the military, married or living independently with court permission.

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.

A term used instead of defendant or appellee in some states -- especially for divorce and other family law cases -- to identify the party who is sued and must respond to the petitioner's complaint.
