A revocable trust can be changed or dissolved by the person who created it (the grantor) at any time during their life and offers no asset protection or estate-tax benefit. An irrevocable trust generally cannot be changed once established, but removes the assets from the grantor's taxable estate and can offer creditor protection.
Why It Matters
The choice between the two structures is central to nearly every estate plan above a modest size — revocable trusts solve for probate avoidance and incapacity planning, while irrevocable trusts solve for estate-tax reduction and asset protection, and confusing the two (or drafting one when the client's actual goal requires the other) is a common and costly planning error.
How It Works in Practice
- 1Revocable (living) trusts: assets remain part of the grantor's taxable estate, but avoid probate and provide a mechanism for incapacity management
- 2Irrevocable trusts: assets are permanently transferred out of the grantor's control and estate, which is what unlocks estate-tax and creditor-protection benefits
- 3Common irrevocable structures include Irrevocable Life Insurance Trusts (ILITs), Grantor Retained Annuity Trusts (GRATs), and Spousal Lifetime Access Trusts (SLATs)
- 4Trust decisions interact directly with the federal estate and gift tax exemption, which is scheduled to be affected by sunset provisions unless extended by Congress
Common Pitfalls
Clients frequently overestimate what a revocable trust accomplishes — it does not reduce estate taxes or protect assets from creditors, despite common misconceptions
"Irrevocable" is a strong word but not always absolute — some jurisdictions permit decanting or trust modification under specific circumstances, and drafting should account for that flexibility deliberately, not by accident
Funding failures — creating a trust but never actually retitling assets into it — are extremely common and defeat the purpose of the entire structure
