People that have assets that exceed the exclusion amount ($5.25 million in 2013) most certainly need to discuss tax efficiency strategies with a licensed estate planning attorney who places an emphasis on wealth preservation.
However, there are those who the only reason someone would meet with an estate planning lawyer is to avoid taxes. They may reason that because their estate is less than the exclusion amount, there is no need for estate planning. In fact, there are myriad concerns that can be addressed with a properly constructed estate plan that have nothing to do with tax exposure.
One of these concerns could be long-term access to financial resources. You may be concerned about leaving lump sum inheritances to certain people on your inheritance list. After all, you won't be around to help if someone in the family was to burn through his or her inheritance too quickly.
A way to respond to this would be to convey assets into a spendthrift trust. You appoint a trustee, and this could be a family member, the trust department of a bank, or a trust company. This trustee will administer the funds according to your stated wishes and distribute assets to the beneficiary in a measured fashion. The beneficiary will not be able to control the principal, which also means their creditors would not have access, either.
This is only one possible scenario. There are many others, including planning for blended families and providing for a family member with special needs without jeopardizing disability benefits.
Arranging for the transfer of your financial assets to your loved ones is a profound act. It is something that is best undertaken with the benefit of professional guidance.
