Christopher 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.

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).

An annual income figure for which there are as many families with incomes below that level as there are above that level. The Census Bureau publishes median family income figures for each state and for different family sizes. A debtor whose current monthly income is higher than the median family income in his or her state must pass the means test in order to file for Chapter 7 bankruptcy, and must commit all disposable income to a five-year repayment plan if filing for Chapter 13 bankruptcy.

A situation in which the partners in a married couple live apart. Spouses are said to be living apart if they no longer reside in the same dwelling, even though they may continue their relationship. A legal separation results when the parties separate and a court rules on the division of property, such as alimony or child support -- but does not grant a divorce.

A lie by one spouse before marriage that provides grounds for an annulment. For example, if a spouse failed to mention that he was still married or was incapable of having children, he has misrepresented himself.

A child born to your spouse before your marriage whom you have not legally adopted. If you adopt the child, he or she is legally treated just like a biological offspring. Under the Uniform Probate Code, followed in some states, a stepchild belongs in the same class as a biological child and will inherit property left 'to my children.' In other states, a stepchild is not treated like a biological child unless he or she can prove that the parental relationship was established when he or she was a minor and that adoption would have occurred but for some legal obstacle.

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.
