Ullin Divorce & Family Law Lawyer, Illinois

A doctrine that grants the spouse least at fault a divorce when both spouses have shown grounds for divorce. It is a response to an old common-law rule that prevented a divorce when both spouses were at fault.

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.

A situation set up so that another person commits a wrongdoing. For example, a husband who invites his wife's lover along on vacation may have connived her adultery, and if he tried to divorce her for her behavior, she could assert his connivance as a defense.

A custody arrangement in the case of multiple children, awarding sole custody of one child to one parent and sole custody of another child to the other parent. This arrangement is generally disfavored by judges because they are reluctant to split up siblings.

A person, not necessarily a lawyer, who is appointed by a court to represent and protect the interests of a child or an incapacitated adult during a lawsuit. For example, a guardian ad litem (GAL) may be appointed to represent the interests of a child whose parents are locked in a contentious battle for custody, or to protect a child's interests in a lawsuit where there are allegations of child abuse. The GAL may conduct interviews and investigations, make reports to the court and participate in court hearings or mediation sessions. Sometimes called court-appointed special advocates (CASAs).

In some states, a type of marriage in which couples can become legally married by living together for a long period of time, representing themselves as a married couple and intending to be married. Contrary to popular belief, the couple must intend to be married and act as though they are for a common law marriage to take effect -- merely living together for a long time won't do it.

A person, usually a relative, who appears in court on behalf of a minor or incompetent plaintiff, but who is not a party to the lawsuit. For example, children are often represented in court by their parents as 'next friends.'
