Dryden Divorce & Family Law Lawyer, Washington

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.

Secret cooperation between two people in order to fool another. Collusion was often practiced by couples before no-fault divorce in order to make up a grounds for divorce (such as adultery). By fabricating a permitted reason for divorce, colluding couples hoped to trick a judge into granting their freedom from the marriage. But a spouse accused of wrongdoing who later changed his or her mind about the divorce could expose the collusion to prevent the divorce from going through.

A court judgment that is not final until the judge decides other matters in the case or until enough time has passed to see if the interim decision is working. In the past, interlocutory decrees were most often used in divorces. The terms of the divorce were set out in an interlocutory decree, which would become final only after a waiting period. The purpose of the waiting period was to allow the couple time to reconcile. They rarely did, however, so most states no longer use interlocutory decrees of divorce.

A child placed by a government agency or a court in the care of someone other than his or her natural parents. Foster children may be removed from their family home because of parental abuse or neglect. Occasionally, parents voluntarily place their children in foster care. See foster care.

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.

The entitlement of all children to be supported by their parents until the children reach the age of majority or become emancipated -- usually by marriage, by entry into the armed forces or by living independently. Many states also impose child support obligations on parents for a year or two beyond this point if the child is a full-time student. If the parents are living separately, they each must still support the children. Typically, the parent who has custody meets his or her support obligation through taking care of the child every day, while the other parent must make payments to the custodial parent on behalf of the child -- usually cash but sometimes other kinds of contributions. When parents divorce, the court almost always orders the non-custodial parent to pay the custodial parent an amount of child support fixed by state law. Sometimes, however, if the parents share physical custody more or less equally, the court will order the higher-income parent to make payments to the lower-income parent.

A court procedure by which an adult becomes the legal parent of someone who is not his or her biological child. Adoption creates a parent-child relationship recognized for all legal purposes -- including child support obligations, inheritance rights and custody.

The ability of a prospective adoptive parent to provide for the best interests of a child. A court may consider many aspects of the prospective parents' lives in evaluating their fitness to adopt a child, including financial stability, marital stability, career obligations, other children, physical and mental health and criminal history.
