Home › Illinois Estate Planning › Living Trust Cost
A living trust in Illinois costs $1,500 – $4,000 attorney-drafted, $2,500 – $6,000 for a couple’s full plan, or $100–$600 online. Illinois is also one of 13 jurisdictions with its own estate tax, and its exemption is $4 million — against a federal exemption of $15 million. Estates that owe the IRS nothing can still owe Illinois.
With a $4 million state exemption, planning here starts earlier than most states.
If your assets are in Illinois only, with no blended family and no estate-tax exposure, an online service like Trust & Will produces a complete Illinois trust in about an hour.

How to estimate probate costs in Illinois
For a useful probate estimate, ask for an itemized quote based on the assets that actually require administration. Keep court charges, professional compensation, taxes, and the cost of creating a trust separate.
| Ask about | What the estimate should explain |
|---|---|
| Court and filing charges | Which procedure is needed, the current court fee schedule, and any later filings. |
| Executor or administrator compensation | The applicable fee rule, the assets included in its calculation, and whether compensation will be claimed. |
| Attorney fees | The billing method, work included, and charges for disputes or unusual assets. |
| Other administration expenses | Whether publication, bond, appraisals, accounting, tax preparation, or property sales add costs. |
This is a quote checklist, not a statewide price schedule. Trust-drafting prices, inheritance-tax rates, and a spouse’s inheritance share do not belong in a probate-fee total.

What each price point buys in Illinois
- $100–$600 (online): A valid Illinois trust document, pour-over will, and directives. You do the funding — every Illinois deed transfer, every account retitling.
- $1,500 – $4,000 (attorney, individual): Custom drafting, review of how your assets are titled, and usually one deed included. Confirm that last part before you sign.
- $2,500 – $6,000 (attorney, couple): Adds marital property planning, plus credit shelter planning against the $4 million state exemption.
Does your estate even need probate in Illinois?
Before paying for anything, check whether Illinois would require full probate at all. The state’s simplified route: Personal property ≤$150,000 (effective Aug 2025) — 755 ILCS 5/25-1 Estates that fit under it can often transfer by affidavit or summary procedure, with no personal representative and no attorney — which makes a trust a convenience decision rather than a cost-avoidance one. For assets that do require administration, request a quote for the applicable procedure.
Trust vs. probate in Illinois
| Consideration | With a funded living trust | Assets requiring probate |
|---|---|---|
| Costs to compare | Document preparation, asset transfers, later updates, and administration after death. Ask separately about trustee, legal, and accounting charges. | Court charges, executor or administrator compensation, legal fees, and other administration expenses. Request an itemized estimate. |
| Timing | Ask how debts, taxes, property sales, and distributions affect the settlement schedule; avoid assuming an immediate payout. | Ask about the required court process, creditor deadlines, and any sales or disputes that could delay closing. |
| Records | Ordinary trust administration generally takes place outside probate court; a court dispute can still create public records. | Probate involves court filings; ask the court which records are public. |
Compare the same assets and services on both sides. A trust’s purchase price alone is not its lifetime cost, and assets left outside the trust may still need probate. See how to fund a trust.

Online or Illinois Attorney?
| Situation | Route |
|---|---|
| Assets only in Illinois, standard estate | Online service |
| Estate near Illinois’s $4 million state exemption | Attorney |
| Property in 2+ states, blended family, business | Attorney |
The dividing line is funding, not drafting. Online documents are valid in Illinois; what they don’t do is retitle your assets. See funding your trust.
Other Illinois rules that affect the plan
- Does NOT reduce Illinois estate tax: — trust assets are still part of your taxable estate
- Can reduce estate tax: — assets transferred irrevocably are removed from the taxable estate (critical with the $4M cliff)
- Credit shelter trust: — preserves the first spouse’s $4M Illinois exemption (essential because IL has no portability)
- ILIT: — keeps life insurance proceeds outside the estate entirely (life insurance counts toward the $4M threshold)
- Medicaid Asset Protection Trust: — can protect assets from Illinois Medicaid recovery if established 5+ years before applying
- Estate tax: $4M exemption (cliff effect), graduated rates up to 16%
- No portability: at the state level
- Filing: Form 700 with IL Attorney General, due 9 months after death
- Common law: (separate property) state
- TOD deeds: Available for residential real property (755 ILCS 27/)
- Trust income tax: 4.95% + 1.5% replacement tax = 6.45%
- Personal property: $150,000 or less (increased from $100,000 effective August 15, 2025)
Recent Illinois Changes Worth Knowing
- August 2025 — Small Estate Affidavit Threshold Increased: Personal property limit raised from $100,000 to $150,000 (755 ILCS 5/25-1). More families can now transfer personal property without opening a probate estate.
- January 2026 — Homestead Exemption Tripled (Public Act 104-120): The creditor homestead exemption increased from $15,000 to $50,000 per individual ($100,000 co-owned). The most significant increase in decades.
- Pending — HB 1457: Would raise the estate tax exemption from $4 million to $12,060,000, aligning with the former federal level. Status: introduced in the 104th General Assembly.
- Pending — HB 2368: Would replace the cliff-effect credit method with a straightforward graduated rate structure (5%/10%/16%/22%) and true $4M deduction. Would eliminate the cliff effect entirely. Status: introduced in the 104th General Assembly.
- Federal — One Big Beautiful Bill Act (July 2025): The federal estate tax exemption is now permanently set at $15 million per individual. Illinois remains at $4 million. The gap continues to grow — making state-level planning more important than ever.

When to Hire An Illinois Attorney
Online stops being the right answer when the estate has moving parts: property in more than one state, a blended family, a business, or anyone you intend to exclude.
- Get two or three flat-fee quotes. Identical work varies by $1,000+ inside one metro.
- Ask what’s included. Deed transfers run $150–$400 each and are often quoted separately.
- Don’t buy complexity you don’t have.
Three ways to pay less in Illinois
- Price the state tax exposure first. With a $4 million Illinois exemption, an estate anywhere near that line should be quoted for credit shelter planning, not a basic trust — the cheap package solves the wrong problem.
- Count the deeds before comparing prices. At $150–$400 apiece, with properties in multiple counties each needing their own recorded transfer, a quote including one deed can beat a cheaper quote including none.
- Check the simplified threshold first. Personal property ≤$150,000 (effective Aug 2025) — 755 ILCS 5/25-1 If your estate clears that, you may be buying convenience rather than savings.

FAQ
How much does a living trust cost in Illinois?
$1,500 – $4,000 attorney-drafted, $2,500 – $6,000 for a couple’s full estate plan, or $100 to $600 through an online service. Add $150 to $400 per property for the deed transfers that fund it.
Does a living trust avoid Illinois estate tax?
No. A revocable trust is tax-neutral; it avoids probate, not the Illinois estate tax. With a $4 million exemption, reducing that liability takes specific planning such as a credit shelter trust or an ILIT.
Can I make my own living trust in Illinois?
Yes — online services produce valid Illinois documents. The risk is funding: a trust that doesn’t hold title to your home doesn’t avoid probate for it.
Can a small estate skip probate in Illinois?
Often, yes. Illinois’s simplified threshold: Personal property ≤$150,000 (effective Aug 2025) — 755 ILCS 5/25-1 Estates under it may transfer without full administration, which changes whether a trust is worth paying for.
How long does probate take in Illinois?
The timetable depends on the procedure, creditor deadlines, taxes, property sales, and any disputes. Ask for an estimate based on the actual estate. A funded trust may avoid probate for trust assets, but settling the trust still takes time.
If the online route fits your situation, Trust & Will’s trust plan covers Illinois and takes about an hour.
