Good estate planning contemplates potential future life changes. If the right planning is in place, a Will or Trust will remain viable for a long time. Sometimes life throws curve-balls (sudden death of a loved one, divorce, dramatic financial changes) that necessitate some changes to an existing estate plan. Also, laws sometime change in a manner that make it desirable to revisit existing estate planning.
So how do I know if I need to review my documents? A review every few years is a good idea. If it has been 10 or so years, a review is a really good idea. Whether changes would be beneficial will ultimately depend mostly on personal preferences and goals, coupled with the effects of any changes in life or in the law. I offer a free review at any time for any existing client. I also offer a review for new clients at a very modest cost.
