Erin Divorce & Family Law Lawyer, Ontario

A federal law that requires employers to provide an employee with 12 weeks of unpaid leave during a year's time for the birth or adoption of a child, family health needs or personal illness. The employer must allow the employee to return to the same position or a position similar to that held before taking the leave. There are exceptions to the FMLA: the most notable is that only employers with 50 or more employees are covered--about half the workforce.

A mistake by both spouses in a marriage that can serve as grounds for an annulment. For example, if one spouse went into the marriage wanting children while the other did not, they have a misunderstanding that will be judged serious enough for a court to terminate the marriage.

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.

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.

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 court decision that is intended to prevent harm--often irreparable harm--as distinguished from most court decisions, which are designed to provide a remedy for harm that has already occurred. Injunctions are orders that one side refrain from or stop certain actions, such as an order that an abusive spouse stay away from the other spouse or that a logging company not cut down first-growth trees. Injunctions can be temporary, pending a consideration of the issue later at trial (these are called interlocutory decrees or preliminary injunctions). Judges can also issue permanent injunctions at the end of trials, in which a party may be permanently prohibited from engaging in some conduct--for example, infringing a copyright or trademark or making use of illegally obtained trade secrets. Although most injunctions order a party not to do something, occasionally a court will issue a 'mandatory injunction' to order a party to carry out a positive act--for example, return stolen computer code.

A term generally meaning all your children and their children down through the generations, including grandchildren, great-grandchildren, and so on. Also called 'lineal descendants.'

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.
