What this means in practice
Sign the will in front of all the witnesses at the same time and have them sign right after you. Many people choose adult witnesses who receive nothing under the will, which avoids questions later.
Keep the signed original somewhere safe and tell your executor where it is. A copy is usually not enough to probate a will.
Changing a will later takes the same formalities: sign a codicil or a new will with witnesses, rather than writing changes on the original.
