Wills generally don’t need to be notarized in order to be legally binding, however, they do require “credible” witnesses. Generally, it is recommended that the witnesses to the Will be “disinterested”, which means that they are not beneficiaries of the Will.

In Texas, the signing of a Will by an interested witness does not invalidate the Will but the gift to the witness is void unless there are at least two disinterested witnesses to the Will.
