There are two issues surrounding where a case will be filed - jurisdiction and venue. There is a course in law school dedicated almost entirely to these issues (civil procedure), so unfortunately I can't give a comprehensive answer to the question that suits every situation. The general rule is that cases must be filed in the state and county where the person you're filing against lives, but divorce and family law have more exceptions to that rule than probably any other area of law.
I already have a will. Do I need a new one?
While attorneys do our best to draft wills that are durable, and will reflect your wishes in a variety of scenarios (related to who may or may not survive you, who will serve as executor, etc.), your will may need to be updated when 1) your wishes change, 2) your situation changes, or 3) the law changes.
The house is in my spouse's name, not mine. Am I in trouble here?
How much should I ask for/offer?
Will I have to go to court?
If you have a case where you and your ex can't agree on all of the issues presented, you'll have to go to court. If you're able to agree on all the issues, you most likely won't.
Going to court - especially for the first time - can be an intimidating thought. But really, it's probably not what you're thinking.
Is my living will still valid?
Living wills have been around for a long time, but most people were very careless about creating or maintaining these essential documents. That changed in 2005 due to the highly publicized Terry Schiavo case. Since that time, many people have created living wills - often through forms they've been given by friends, their church, or that they've found online. If you have a living will made through any of these forms, and something happens to you, the hospital caring for you (and if necessary, the courts) WILL try to honor the wishes expressed in those documents.
But you shouldn't have a living will at all.
