When an individual creates an estate plan, it is not necessarily set in stone. Their desires and the conditions that affect the estate may change over time. For this reason, it is best to review estate plans every two to three years or any time major life changes occur, including:nn- Moving to another staten- Deciding to sell or purchase a businessn- Substantial changes in the classification of assetsn- Any major increase or decrease in the individual’s net worth, or that of any beneficiaryn- Any marriage, divorce, birth, death, or disability of the individual or one of their beneficiariesn- Changes in tax laws
