Codicil
A short document that amends an existing will instead of replacing it.
What Codicil means in an estate
A codicil changes, adds to, or revokes part of a will while leaving the rest in force. It generally must be signed and witnessed with the same formalities as a will, and those formalities vary by state. Because a codicil that conflicts with the original creates ambiguity (and one more document to lose), most people today simply sign a new will.
How this works in your state
The concept is national, but the forms, procedure names, thresholds, and filing practice vary by state. Open your state glossary and guides to see how codicil is handled where the estate is being settled.
