please please please at least talk to an attorney and yes I am an attorney so of course my advice is biased BUT..
MANY MANY MANY people have no clue about estate law and what can/can't be done even with small estates.
I also find that a person's idea of a small estate and what a true small estate is under the law are two vastly different things.
A good attorney will be able to walk you through a lot of possibilities, including discussions on how you have property titled and how that will effect your estate. What happens when the 1st spouse dies for the 2nd spouse etc..
Further, if you have children, you need to have a frank discussion with an attorney regarding distribution for the children, guardianship, life insurance etc..
I've had too many clients in my office who come in saying they have a simple estate and leave my office looking at decisions they never even thought of.
I know around here it is about $150-$200 per person for a will and usually about $300 per person for a will, poa and health directive. It is really not a lot of money to make sure it is done correctly versus the huge legal mess and much higher costs in fees to your estate if it's not.
