First, you need a will, everyone does.  What no one tells you is that a will must be approved by a court and that costs thousands.

Our estate plans are designed to save money by avoiding the need to go to court and “probate” the will.

In my opinion, it is a mistake to do the wills yourself because it is supremely easy to make a catastrophic mistake and have things distributed wrong.  Even the forms say to fill them out and have a lawyer review them — which will end up costing money again. 

But if you are determined to do so, here are the free forms from the State of Texas approved by the Supreme Court of Texas:
