Weaknesses and limitations

Funding and administration

Issue Consequence
Unfunded revocable trust Probate still required for titled assets; plan fails main benefit
Wrong titling Assets pass by will or law, not trust terms
Stale beneficiary designations IRA/insurance overrides trust intent
No successor trustee named Court or family dispute delays administration

Tax limitations

Issue Consequence
Step-up lost on lifetime gifts Donee takes carryover basis; estate tax saved but income tax on appreciation
Grantor trust status Income taxed to grantor — intended in IDGT, surprise in poorly drafted ILIT
Compressed trust brackets Undistributed income taxed heavily at trust level
QTIP inclusion at second death Marital deduction at first death; full inclusion later
Portability not elected Lost DSUE if no timely Form 706
IRD assets No basis step-up; estate and beneficiaries share IRD deduction rules
State estate tax Illinois threshold below federal; bypass planning still relevant for state

Legal and practical

  • Trusts do not shield assets from creditors of grantor while revocable.
  • Irrevocable trusts may trigger Medicaid look-back (not sourced here).
  • Dynasty trusts limited by state rule against perpetuities (Illinois: prudent period rule).
  • Divorce remarriage may conflict with prior trust beneficiaries.
  • Co-trustee friction and family disputes increase with complexity.

Cost vs benefit

Simple estate (under federal exclusion, no state issues): RLT may add cost with limited tax benefit. Complex families, real property in multiple states, or estate tax exposure: trusts often justify cost.

Roth + trust-specific

See roth-iras-and-trusts.md: improper trust beneficiary designation is a frequent expensive error.
