Irrevocable trusts are required if you want to engage in estate tax planning, asset protection planning (creditor planning) and even in a great deal of income tax (including capital gains tax) planning. However, parents are not thrilled at the idea of having to give away assets to a trust that they cannot revoke!! Do you mean that they can't change it? What if they change their minds about their children? About the trustee? Happily, there are many ways to make the parents comfortable that even though the trust itself is unable to be revoked, it is flexible. The parents, of course, pick as the initial trustee the person they trust to do whatever he or she is told without question but simply out of loyalty. More importantly, the parents can - at any time, without a reason - remove the trustee and name a new one (as long as the new one is not "related or subordinate" as defined in IRC Section 672(c)). The parents can advise the trustee to drop the assets down into a single member LLC and appoint the parents as the non-managing members. The trust can have a protector who can be given the power to remove the trustee; to change the allocation among the children; to add grandchildren and spouses of heirs and charities as beneficiaries; to change the manner of distribution to the heirs. Under California law if all of the beneficiaries and the grantors agree, they can amend an irrevocable trust without having to go to court. There are also other ways to change an irrevocable trust, e.g., decanting to a new trust with better provisions. The trust can start off as a grantor (disregarded) trust for income tax purposes and it can "flip" or "toggle" to a complex trust and, perhaps, flip back again. So, the goal of this presentation is to make people aware that there are ways to make parents comfortable with irrevocable trusts, without which planning would be difficult, if not impossible.
