Although there is no hard and fast rule on how often you should update your trust, conducting an annual review of the trust and asset schedule is recommended. In most situations, updates are typically needed every 3-5 years. Circumstances change. There will always be changes in the law – especially the tax laws. There are also going to be changes in your family situation or make-up and your assets will change over time. Being proactive is worth its weight in gold and will ensure your true intentions are followed down the line.
