Time is money...and the time spent with an attorney can be expensive.
My thinking is that an inexpensive or free program for making your own will, should be the first step. It's where you learn definitions and options and all by itself, to complete can take several hours.
A starting point that will save much time of explaining, and may very well offer some options that a standard estate lawyer might skip.
Other parts of this, that need not be done in a lawyers office, are the DNR and other life decisions, and a full listing of assets to be included in a trust.
Our initial foray into this was an eye opener. Inclusions, exclusions and the decision as to whom to appoint as executor are some things that we spent a lot of time deciding... ending up far apart from our initial expectations after digging into the requirements.
We are quite familiar with situations where persons trusted in a lawyer, only to find out that they never really understood the implications of their decision.
So... while I agree that a lawyer must be used to draft a valid will or trust, it will be very helpful to go through the planning, bit by bit, to truly understand the specifics. In the long run, it may not save any money, but will give peace of mind.
By means of explanation, I cite a case where the will was drawn up by a well regarded attorney, based on trust. Because of some simple misunderstandings, the will was held up for two+ years... during a time when interest rates were very high... 10%+ , the funds were frozen in a bank, at a legal interest rate or 2%.
