Understanding Codicils: A Simple Guide to Amending Your Will
Learn what a codicil is, when to use one, and how it can help you update your will without creating an entirely new document. Essential information for singles, parents, and high net worth individuals.
Introduction
A codicil is a legal document that allows you to make minor changes or additions to your existing will without having to rewrite the entire document. Think of it as an amendment or supplement to your will. Codicils must be executed with the same formalities as a will (signed, dated, and witnessed) to be legally valid. Whether you're single without children, married with a family, or have substantial assets, understanding how and when to use a codicil can save you time and money while ensuring your final wishes are properly documented and legally binding.

Key Things to Know
- 1
A codicil must be executed with the same legal formalities as a will—signed, dated, and properly witnessed according to your state's laws—to be valid.
- 2
Store your codicil with your original will to ensure they're found together when needed. Consider informing your executor about the existence of both documents.
- 3
Multiple codicils can create confusion and increase the risk of contradictions or legal challenges. If you've already made several codicils, creating a new will may be clearer.
- 4
Life events such as marriage, divorce, birth of children, or significant changes in assets should trigger a review of your will and consideration of whether a codicil is appropriate.
- 5
For high net worth individuals, even small changes via codicil can have significant tax implications. Always consult with a tax professional or estate attorney before making changes.
- 6
Digital assets (cryptocurrency, online accounts, digital files) are increasingly important to include in estate planning. Consider using a codicil to address these if they weren't in your original will.
- 7
Self-created codicils using online templates carry higher risks of invalidity. The modest cost of professional legal assistance is usually worth the peace of mind, especially for valuable estates.

Colorado Requirements for Codicil
Testamentary Capacity (C.R.S. § 15-11-501)
The testator must be of sound mind, at least 18 years old, and understand the nature of making a codicil, the extent of their property, and the natural objects of their bounty.
Writing Requirement (C.R.S. § 15-11-502)
A codicil must be in writing to be valid under Colorado law.
Signature Requirement (C.R.S. § 15-11-502(1)(b))

The codicil must be signed by at least two individuals, each of whom signed within a reasonable time after witnessing either the signing of the codicil or the testator's acknowledgment of that signature or acknowledgment of the codicil.
Self-Proving Affidavit (C.R.S. § 15-11-504)
A codicil may be simultaneously executed with an attached affidavit of the testator and witnesses, making it self-proving and eliminating the need for witness testimony during probate.
Holographic Codicil (C.R.S. § 15-11-502(2))
A codicil that is not witnessed is valid as a holographic codicil if the signature and material portions of the document are in the testator's handwriting.
Revocation by Subsequent Will (C.R.S. § 15-11-507(1)(a))
A codicil or any part thereof is revoked by a subsequent will that revokes the codicil or part expressly or by inconsistency.
Revocation by Physical Act (C.R.S. § 15-11-507(1)(b))
A codicil is revoked by performing a revocatory act on the codicil with the intent to revoke, including burning, tearing, canceling, obliterating, or destroying the codicil.
Revival of Revoked Codicil (C.R.S. § 15-11-509)
If a subsequent will that wholly revoked a previous will is thereafter revoked by a revocatory act, the previous will remains revoked unless it is revived.
Incorporation by Reference (C.R.S. § 15-11-510)
A writing in existence when a codicil is executed may be incorporated by reference if the language of the codicil manifests this intent and describes the writing sufficiently.
Events of Independent Significance (C.R.S. § 15-11-511)
A codicil may dispose of property by reference to acts and events that have significance apart from their effect upon the dispositions made by the codicil.
Interested Witness (C.R.S. § 15-11-505)
A codicil is not invalid because it is signed by an interested witness, though a gift to a witness may be void unless there are at least two other disinterested witnesses.
Choice of Law (C.R.S. § 15-11-506)
A codicil is valid if executed in compliance with Colorado law or the law of the place where it was executed, or of the law of the place where at the time of execution or at the time of death the testator was domiciled.
Simultaneous Death (C.R.S. § 15-11-712)
If the order of deaths cannot be determined, and there is no sufficient evidence that persons have died otherwise than simultaneously, the property of each person shall be disposed of as if they had survived.
Anti-Lapse Provision (C.R.S. § 15-11-603)
If a devisee who is a grandparent or a descendant of a grandparent of the testator is dead at the time of execution of the codicil, fails to survive the testator, or is treated as if they predeceased the testator, the descendants of the deceased devisee take in place of the deceased devisee.
Ademption by Extinction (C.R.S. § 15-11-606)
A specific devise fails if the property is not in the testator's estate at death, subject to exceptions.
Exoneration (C.R.S. § 15-11-607)
A specific devise passes subject to any mortgage interest existing at the date of death, without right of exoneration, regardless of a general directive in the codicil to pay debts.
Exercise of Power of Appointment (C.R.S. § 15-11-608)
A general residuary clause in a codicil does not exercise a power of appointment held by the testator unless specific reference is made to the power or there is some other indication of intention to exercise the power.
Uniform Simultaneous Death Act (26 U.S.C. § 2518)
Federal law that provides rules for determining succession when there is insufficient evidence to determine the order of deaths.
Federal Estate Tax Considerations (26 U.S.C. § 2001 et seq.)
Codicils should consider federal estate tax implications, including marital deductions, charitable deductions, and generation-skipping transfer taxes.
