If you want to preserve as much wealth as possible for your children, but you leave property to your spouse outright, there’s no guarantee your objective will be met. This may be a concern if your spouse has poor money management skills or if you two don’t see eye to eye on how assets should be distributed to your children. It could also be a concern if you have children from a previous relationship; you may want to provide for a current spouse while he or she is alive, but have your assets go to your children upon your spouse’s.
