FYI, everyone, trusts and wills can have very specific and rather arcane requirements that vary by jurisdiction. For example, a "holographic wills" in California must be entirely in the testator's handwriting, and there are specific witness requirements. If your bequests and your trusts are important, I can't think of a more dangerous way of proceeding than with pre-printed or software-generated forms that are not at least reviewed by a lawyer.

Proceed at your own risk.
