When does a revocable trust make sense vs an irrevocable trust?

Revocable and irrevocable trusts serve very different purposes. Each has clear use cases. Here's the framework.

Revocable trust use cases:

1. Probate avoidance. Assets held in a revocable trust pass to beneficiaries WITHOUT going through probate court at the grantor's death. Saves time (months to years), money (1-7% of estate value in probate fees), and privacy (probate is public record).

1. Incapacity planning. If the grantor becomes incapacitated (dementia, stroke, coma), the successor trustee can immediately step in to manage trust assets — no need for court-appointed conservator.

1. Privacy. A revocable trust isn't public. Wills become public when probated. For families that don't want their wealth distribution exposed publicly, revocable trusts maintain confidentiality.

1. Coordinated multi-property management. If you own real estate in multiple states, each would normally require separate probate in that state ("ancillary probate"). A revocable trust holds all properties in one entity, avoiding multiple probates.

1. Quick succession. Successor trustee can act immediately after grantor's death — no waiting for court orders or executor's letters.

Important: revocable trust does NOT save estate taxes.

Assets in a revocable trust are STILL in the grantor's estate for estate-tax purposes. The trust doesn't magically shrink the estate.

Irrevocable trust use cases:

1. Estate tax reduction. Assets in an irrevocable trust are NOT in the grantor's estate (assuming proper grantor-trust analysis). Removes assets from the 40% estate tax exposure above the exemption.

1. Generation-skipping transfer (GST) planning. With GST exemption allocated, a dynasty trust can pass wealth through multiple generations without GST tax.

1. Asset protection from creditors. Properly structured irrevocable trusts (especially DAPTs or offshore trusts) shield assets from grantor's future creditors.

1. Beneficiary protection. Discretionary irrevocable trusts shield beneficiaries from their own creditors, divorcing spouses, and bad decisions.

1. Long-term wealth preservation. Dynasty trusts can last for generations or perpetually, locking in multi-generational wealth-transfer plans.

The trade-off table:

The combined strategy:

Many wealthy families use BOTH:

1. Revocable living trust as their main "ownership" structure for personal-use assets (home, primary brokerage account, cars). Handles probate avoidance and incapacity.

1. Multiple irrevocable trusts for wealth-transfer purposes:

• GST-exempt dynasty trust for long-term family wealth
• SLAT (spousal lifetime access trust) for spouse-and-children
• GRAT for high-growth assets
• QPRT for primary residence
• ILIT for life insurance
• Asset-protection trust for risky-business assets

The architecture varies dramatically by family wealth level, ages, and goals. A standard middle-class family might have ONLY a revocable living trust. An ultra-wealthy family ($100M+) might have 8-15 different trusts.

Common confusion to avoid:

• "I don't want my wealth to go through probate" → revocable living trust is sufficient. Not the same as estate tax reduction.
• "I want to save estate tax" → revocable trust does NOT save estate tax. You need irrevocable.
• "I want asset protection" → revocable trust does NOT provide it. You need irrevocable + careful structuring.

For the exam:

CFA L3 tests this distinction directly. Know:

• Revocable = probate + incapacity + privacy (no tax/protection benefits)
• Irrevocable = tax + creditor protection (loss of control as price)
• Combined strategies for wealthy families
• Common misunderstandings (probate vs. estate tax)
