Latin for 'in chambers.' A legal proceeding is 'in camera' when a hearing is held before the judge in her private chambers or when the public is excluded from the courtroom. Proceedings are often held in camera to protect victims and witnesses from public exposure, especially if the victim or witness is a child. There is still, however, a record made of the proceeding, typically by a court stenographer. The judge may decide to seal this record if the material is extremely sensitive or likely to prejudice one side or the other.

A person who initiates a lawsuit. A synonym for plaintiff, used almost universally in some states and in others for certain types of lawsuits, most commonly divorce and other family law cases.

A person who supports and maintains, in one household, one or more people who are closely related to him by blood, marriage or adoption. Under federal income tax law, you are eligible for favorable tax treatment as the head of household only if you are unmarried and you manage a household which is the principal residence (for more than half of the year) of dependent children or other dependent relatives. Under bankruptcy homestead and exemption laws, the terms householder and 'head of household' mean the same thing. Examples include a single woman supporting her disabled sister and her own children or a bachelor supporting his parents. Many states consider a single person supporting only himself to be a head of household as well.

Differences between spouses that are considered sufficiently severe to make married life together more or less impossible.

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.
