You should review your will every three to five years, or whenever you have a major life change like marriage, divorce, birth of a child, or significant changes in your assets. Life changes, and your will should change with it. Many people forget to update their will after major life events, which can create serious problems later. If you get divorced but don’t update your will, your ex-spouse might still inherit your assets in New York. If you have more children but don’t update your will, the new kids might not be provided for properly. Similarly, if you acquire most significant new assets like a business or investment property, your will should reflect those changes to ensure everything is distributed according to your current wishes, not your old ones.
