A codicil is an addition or supplement to a Last Will and Testament, while an amendment typically refers to changes made to a revocable living trust. It’s important to periodically review any estate plan, whether created by a single person or a married couple, to ensure it reflects necessary updates. Various life changes may require a codicil or amendment, including family events like marriages, births, deaths, changes in relationships, disabilities, addictions, financial mismanagement, and more. These personal circumstances should be discussed with your estate planning attorney to determine what adjustments are needed in your estate plan and whether a codicil or amendment is required.

Additionally, changes in state, federal, and tax laws may also impact your will, trust, or other estate planning documents, such as a medical power of attorney, and may warrant a codicil or amendment.
