Laws governing the proper preparation of a Will are historically governed by caution and conservatism. The reason for this is obvious: The system that we have for the conveyance of property after death is of central importance to an orderly society. So change comes rarely. Basic rules governing execution of wills generally require that a will be type-written, signed in the presence of witnesses, and affirmed by at least two witnesses.
But change might be coming.
A judge in Ohio recently approved a will prepared by Javier Castro who, faced with his imminent death, “wrote” the will with his finger using an app on his Samsung Galaxy.
