Irrevocable Trust

An irrevocable trust is a legal arrangement that, once established, generally cannot be changed or revoked by the person who created it.

When a grantor transfers assets into an irrevocable trust, they are typically giving up ownership and control of those assets permanently. That surrender is precisely the point: because the assets no longer legally belong to the grantor, they may be removed from the grantor's taxable estate and placed beyond the reach of many creditors. This concept — moving wealth out of an estate — is central to how many families approach multigenerational planning as part of their broader family office structure.

Consider a founder who sold her logistics company. She might transfer a portion of the proceeds into an irrevocable trust for the benefit of her children and grandchildren. From that point forward, those assets generally follow the trust's terms, not her wishes — which is why thoughtful drafting before signing is critical. Families commonly use irrevocable structures as the legal container for long-horizon assets described in an investment policy statement.

Irrevocable does not always mean completely frozen. Some modern irrevocable trusts include a trust protector — a third party granted limited powers to make adjustments over time. Still, the core principle holds: the grantor cannot simply take assets back. The tax and legal consequences of establishing an irrevocable trust are complex and jurisdiction-specific, so families must work with qualified attorneys and CPAs before proceeding.
