jurisdiction and full faith and credit

Please write a two-page paper discussing the law that applies to the following scenario. You need to write everything in your own words — no quotes please. This should be double spaced using 12-point font, with 1-inch margins all around. You should include in the body of the paper citations for any sources that help you as you are writing the paper. This can include your textbook, my lecture notes, or Internet resources. You must write this yourself — I submit your papers to Turnitin.com, which is a resource teachers use that immediately detects plagiarism. Papers written at another school will show up on there as well as information copied from books and the Internet. Although writing about the law is difficult, you will always do better with me if you try to do it yourself than if you copy.

Scenario: Suppose that Wanda and Tim were married for 6 years. During that time they had two children, Grace and Max. After six years of marriage Wanda and Tim decide to call it quits and get a divorce. However, almost immediately hurt feelings multiply and the parties are at war with each other. Tina gets a lawyer and files a complaint for a divorce and custody of the kids in a Washington court. Tim is not as quick and when he learned that Tina had filed already, he moved to Idaho, got a lawyer, and filed a complaint for divorce and custody there. Eventually the Washington court granted the divorce and full custody to Tina, with visitation given to Tim. The Washington court also left the decree open to modification in the future, as Tim did not appear for the trial.
What should the Idaho court do? Does it have to follow the decision of the Washington court or can it issue its own determination? In analyzing this you should explore the concepts of subject matter and personal jurisdiction, as well as full faith and credit/comity of laws. A good approach to writing about the law is to 1) identify what the issue is (here, it is whether Idaho has to follow the ruling in Washington), 2) state the rule(s) of law (here about jurisdiction and full faith and credit), and 3) apply the law to the facts to show what the result should be and how you arrive at that conclusion.
