How to Change or Amend a Will: Codicil vs. New Will (2026)

Quick Answer

You can amend a will with a codicil or create a new will that revokes the old one. In 2026, most estate attorneys recommend a full rewrite for anything beyond a single beneficiary change because multiple codicils create confusion and legal vulnerability during probate.

Can Wills Be Changed?

Yes. As long as you are mentally competent, you may change your will at any time. However, handwritten notes or crossing out sections can invalidate the document or create probate disputes.

Why Is a Will Not Enough for the First 72 Hours?

A will governs probate, which often begins weeks after death. It does not address the first 72 hours, when families must make urgent decisions about disposition, access funds, and locate documents. This gap—between death and probate—is where most families experience crisis.

What Else Should You Update Alongside Your Will?

Essential Updates Beyond the Will

While you are updating your legal will, do this too:

  • Document immediate disposition preferences and authority (Right of Disposition).
  • List where critical documents, keys, and digital access information are stored.
  • Update beneficiary designations on non-probate assets like 401(k)s and life insurance.

What About Electronic Wills in 2026?

Since it is 2026, many states (including Arizona) now have specific statutes for digital execution of wills. Electronic wills allow for remote witnessing and digital signatures through approved custodial platforms. However, not all states recognize e-wills, so interstate portability remains a concern.

Critical: A new will must include a statement that 'expressly revokes all prior wills and codicils.' Without this revocation clause, a court may attempt to reconcile conflicting documents, leading to costly litigation and delayed probate.
