Olga Divorce Lawyer, Washington

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 special kind of property ownership that's only for married couples. Both spouses have the right to enjoy the entire property, and when one spouse dies, the surviving spouse gets title to the property (called a right of survivorship). It is similar to joint tenancy, but it is available in only about half the states.

The payment made to a lawyer for legal services. These fees may take several forms: hourly per job or service -- for example, $350 to draft a will contingency (the lawyer collects a percentage of any money she wins for her client and nothing if there is no recovery), or retainer (usually a down payment as part of an hourly or per job fee agreement). Attorney fees must usually be paid by the client who hires a lawyer, though occasionally a law or contract will require the losing party of a lawsuit to pay the winner's court costs and attorney fees. For example, a contract might contain a provision that says the loser of any lawsuit between the parties to the contract will pay the winner's attorney fees. Many laws designed to protect consumers also provide for attorney fees -- for example, most state laws that require landlords to provide habitable housing also specify that a tenant who sues and wins using that law may collect attorney fees. And in family law cases -- divorce, custody and child support -- judges often have the power to order the more affluent spouse to pay the other spouse's attorney fees, even where there is no clear victor.

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.

The taking of a child from his or her parent with the intent to interfere with that parent's physical custody of the child. This is a crime in most states, even if the taker also has custody rights.
