Christopher Adoption Lawyer, Illinois

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.

A document used to submit a legal contention or argument to a court. A brief typically sets out the facts of the case and a party's argument as to why she should prevail. These arguments must be supported by legal authority and precedent, such as statutes, regulations and previous court decisions. Although it is usually possible to submit a brief to a trial court (called a trial brief), briefs are most commonly used as a central part of the appeal process (an appellate brief). But don't be fooled by the name -- briefs are usually anything but brief, as pointed out by writer Franz Kafka, who defined a lawyer as 'a person who writes a 10,000 word decision and calls it a brief.'

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 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.

An adoption in which there is some degree of contact between the birthparents and the adoptive parents and sometimes with the child as well. As opposed to most adoptions in which birth and adoption records are sealed by court order, open adoptions allow the parties to decide how much contact the adoptive family and the birthparents will have.

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 right and obligation to make decisions about a child's upbringing, including schooling and medical care. Many states typically have both parents share legal custody of a child. Compare physical custody.
