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.

Minnesota Requirements for Codicil
Testamentary Capacity (Minnesota Statutes § 524.2-501)
The testator must be of sound mind and at least 18 years old when executing the codicil, possessing sufficient mental capacity to understand the nature of the document, the extent of their property, and the natural objects of their bounty.
Writing Requirement (Minnesota Statutes § 524.2-502)
A codicil must be in writing to be valid. Oral codicils are not recognized under Minnesota law.
Signature Requirement (Minnesota Statutes § 524.2-502(1))
The codicil must be signed by the testator or by someone else at the testator's direction and in the testator's conscious presence.
Witness Requirements (Minnesota Statutes § 524.2-502(3))
The codicil must be signed by at least two competent witnesses who witnessed either the signing of the codicil or the testator's acknowledgment of the signature or of the codicil.
Interested Witness (Minnesota Statutes § 524.2-505)
A witness to a codicil who is also a beneficiary is not automatically disqualified, but may be subject to additional scrutiny to ensure no undue influence.
Self-Proved Codicil (Minnesota Statutes § 524.2-504)
A codicil may be simultaneously executed, attested, and made self-proved by acknowledgment of the testator and affidavits of the witnesses, each made before an officer authorized to administer oaths under the laws of the state where execution occurs.
Revocation by Subsequent Will or Codicil (Minnesota Statutes § 524.2-507)
A codicil or any part thereof is revoked by a subsequent will or codicil that expressly revokes the prior codicil or part thereof, or by inconsistency with the subsequent will or codicil.
Revival of Revoked Will (Minnesota Statutes § 524.2-509)
If a subsequent will or codicil that revoked a previous will or codicil is itself revoked, the previous will or codicil remains revoked unless it is revived by the testator's express intent or by the terms of the revocation.
Choice of Law (Minnesota Statutes § 524.2-506)
A written codicil is valid if executed in compliance with Minnesota law or with the law of the place where the codicil was executed at the time of execution, or with the law of the place where the testator was domiciled at the time of execution.
Incorporation by Reference (Minnesota Statutes § 524.2-510)
A codicil may incorporate by reference any document in existence when the codicil is executed if the codicil manifests this intent and describes the document sufficiently to identify it.
Events of Independent Significance (Minnesota Statutes § 524.2-512)
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, whether they occur before or after the execution of the codicil or before or after the testator's death.
Contractual Arrangements Relating to Death (Minnesota Statutes § 524.2-514)
A contract to make or not to revoke a will or codicil can be established only by provisions of a will or codicil stating the material provisions of the contract, an express reference to a contract in a will or codicil, or a writing signed by the decedent evidencing the contract.
Uniform Simultaneous Death Act (Minnesota Statutes § 524.2-702)
If the order of deaths cannot be determined, and there is no sufficient evidence that the persons have died otherwise than simultaneously, the property of each person shall be disposed of as if that person had survived.
Anti-Lapse Provisions (Minnesota Statutes § 524.2-603)
If a devisee who is a grandparent or a lineal 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 predeceased, the issue of the deceased devisee take in place of the deceased devisee.
Ademption by Extinction (Minnesota Statutes § 524.2-606)
A specific devise fails if the property is not in the testator's estate at death, subject to certain exceptions.
Federal Estate Tax Considerations (26 U.S.C. § 2001 et seq.)
Codicils should consider federal estate tax implications, including the unified credit, marital deduction, charitable deduction, and generation-skipping transfer tax.
Federal Gift Tax Considerations (26 U.S.C. § 2501 et seq.)
Lifetime gifts may affect estate planning and should be considered when drafting a codicil, including annual exclusion gifts and the lifetime exemption amount.
Electronic Signatures (Minnesota Statutes § 325L.03(b)(1))
While Minnesota has adopted the Uniform Electronic Transactions Act, it generally does not apply to wills, codicils, or testamentary trusts, which still require traditional signatures.
Undue Influence (Minnesota case law: In re Estate of Torgersen, 711 N.W.2d 545 (Minn. Ct. App. 2006))
A codicil or any provision thereof is invalid if procured by undue influence, which occurs when someone exerts influence that overcomes the testator's free will.
Fraud or Duress (Minnesota common law)
A codicil or any provision thereof is invalid if procured by fraud or duress, which involves deception or compulsion that causes the testator to make dispositions they would not otherwise have made.
