It's my conservative guess that 90% of all families do not have solids estate plans in place. Key reasons for this are typically a lack of time and a lack of money.
The unfortunate fallout from this situation occurs when your successors need an estate plan that does not exist. At that point, the adage, "Failing to plan is a plan to fail" comes to life and your state of residence gets to determine how your assets are split up to your heirs. That is, after the state takes their half.
The source to which I have linked below offers a flat-rate discounted service for will and trust preparation. Their price point is about 1/5th of the going market rate for these services.
