Klosek Law Offices is providing legal guidance on the use of Will Codicils for individuals and families who need to update existing estate planning documents after major life changes without replacing an entire last will and testament.
The firm’s guidance addresses a common estate planning issue involving wills that no longer reflect current family circumstances, property ownership, beneficiary preferences, or fiduciary appointments. A will codicil, also referred to as a will amendment, is a legal document used to make specific changes or additions to an existing will while leaving the remaining provisions of the original document in place.
Estate plans often require review after significant personal or financial changes. These changes may include marriage, divorce, the birth or adoption of a child, the death of a beneficiary, a change in relationship with an executor, the purchase or sale of valuable property, or a substantial shift in financial status. When the change is limited in scope, a codicil may provide a structured way to update the document while preserving the broader estate plan.
Klosek Law Offices’ guidance explains that codicils are commonly used to change executors, add or remove beneficiaries, revise specific gifts, update instructions for personal property, or clarify provisions that may no longer reflect the testator’s current wishes. The firm notes that a codicil must be drafted and executed carefully because it becomes part of the original will and may be reviewed together with that document during probate.
The legal formalities required for a codicil are a central part of the firm’s guidance. To be enforceable, a codicil generally must be in writing, signed by the person making the will, and witnessed in a manner consistent with the requirements that apply to the original will. The person signing the codicil must also have testamentary capacity at the time of execution, meaning the individual must have the legal mental capacity required to make or amend a will.
Klosek Law Offices also notes that execution requirements can vary by state and by the type of estate planning document involved. Proper witnessing is typically a key requirement for a codicil, while notarization may be relevant in some estate planning contexts depending on the jurisdiction and document type. The firm’s guidance emphasizes that individuals should follow the formalities applicable to their state rather than relying on informal updates or assumptions about validity.
Klosek Law Offices cautions that informal updates can create uncertainty. Handwritten notes, unsigned instructions, margin edits, letters, or verbal statements may lead to disputes if they do not meet legal requirements. Ambiguous amendments can also create conflicting instructions between the original will and the later document, leaving beneficiaries, executors, and probate courts to determine the testator’s intent.
For many families, the purpose of a codicil is to preserve continuity while making targeted updates. Rather than preparing a new will for every minor adjustment, a codicil can allow an estate plan to remain current when only a limited change is needed. At the same time, the firm notes that a new will may be more appropriate when changes are extensive, when multiple prior codicils already exist, or when the existing document no longer reflects the overall structure of the estate plan.
The firm’s guidance also addresses the risk of improper revocation. A poorly drafted amendment may unintentionally revoke important provisions or create inconsistencies that affect the administration of the estate. Legal review can help determine whether a codicil is sufficient, whether a new will is advisable, and whether the proposed amendment aligns with any living trust, power of attorney, beneficiary designation, or other estate planning document.
Klosek Law Offices also recommends periodic review of estate planning documents. A review every three to five years may help identify whether a codicil or broader update is needed due to changes in family dynamics, assets, fiduciary appointments, or applicable law. Regular review may also help reduce the likelihood of probate disputes by ensuring that documents reflect current intentions and are executed with the required formalities.
The firm provides legal assistance with will codicils, will amendments, estate planning updates, probate matters, and trust-related issues. Its services include reviewing existing estate planning documents, identifying provisions that may require revision, preparing codicils or replacement wills when appropriate, and helping clients align amendments with the rest of their estate plan.
Klosek Law Offices states that its Will Codicils resource is intended to help individuals understand when a codicil may be appropriate, what legal requirements apply, and why professionally prepared amendments may reduce ambiguity during estate administration.
