Melrose Divorce & Family Law Lawyer, New York

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 legal reason for obtaining either a fault divorce or a no-fault divorce. It is rarely used, however, because of the difficulty of proving both the insanity of the spouse being divorced and that the insanity is incurable.

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 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.

An arrangement by which parents who do not live together share the upbringing of a child. Joint custody can be joint legal custody (in which both parents have a say in decisions affecting the child) joint physical custody (in which the child spends a significant amount of time with both parents) or, very rarely, both.

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.

Overdue alimony or child support payments. In recent years, state laws have made it difficult to impossible to get rid of arrearages; they can't be discharged in bankruptcy, and courts usually will not retroactively cancel them. A spouse or parent who falls on tough times and is unable to make payments should request a temporary modification of the payments before the arrearages build up.

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.
