How much does estate planning cost in Illinois?
It depends on two things: how the plan is built, will-based or trust-based, and how much of your life it has to handle: property, family structure, a business, tax exposure. Most Illinois estate planning lawyers quote a flat fee for a defined set of documents and bill hourly for work outside it. Illinois Rule of Professional Conduct 1.5(b) expects the scope of the work and the basis or rate of the fee to be communicated to you, preferably in writing, before or within a reasonable time after the work starts, so a quote without a scope is not a quote.
This article does not publish fee figures. Every firm's numbers are its own, and a responsible quote follows a conversation about your facts. What it does is explain what moves the price, what you will pay besides the lawyer, what you are paying to avoid, and how to read a quote so you can compare two of them. Our estate planning attorney page describes how an engagement begins.
What is actually in an Illinois estate plan?
A plan is a set of documents that work together. Knowing the pieces is the first step to understanding a quote.
- Will. Under the Probate Act (755 ILCS 5/4-3) a will must be in writing, signed by you, and attested in your presence by two or more credible witnesses. Notarization is not required, but a self-proving affidavit signed before a notary lets the will be admitted without calling the witnesses. The will names an executor, nominates guardians for minor children and directs who receives what. It does not avoid probate; it tells the probate court what to do. See our wills attorney page.
- Revocable living trust. A trust holds title to assets during your life and distributes them at death without a court proceeding. It comes with a pour-over will for anything left outside the trust, and it only works for assets actually retitled into it. See trust attorney.
- Power of attorney for property. Illinois provides a statutory short form (755 ILCS 45/3-3) naming an agent to handle finances if you cannot.
- Power of attorney for health care. A separate statutory form (755 ILCS 45/4-10) for medical decisions, usually paired with a living will. See power of attorney.
- Deeds. A transfer of your home into the trust, or a transfer on death instrument under the Real Property Transfer on Death Instrument Act (755 ILCS 27) that names who receives the property at death. A transfer on death instrument must be signed, attested by two credible witnesses, notarized and recorded before death. See transfer on death instrument.
- Beneficiary designations. Retirement accounts and life insurance pass by the form on file with the company, not by the will. A plan that ignores them is incomplete; our article on beneficiary designations explains why.
Will-based or trust-based: the main cost driver
| Will-based plan | Trust-based plan | |
|---|---|---|
| Core documents | Will, both powers of attorney, living will | Revocable trust, pour-over will, both powers of attorney, living will, certification of trust |
| Real estate | Passes through probate, or by a transfer on death instrument | Deed into the trust, one per property |
| Signing | Will: two witnesses; powers of attorney: witness and notary | The same, plus notarized deeds |
| Recording | Only if a transfer on death instrument is used | Each deed is recorded |
| At death | Probate in the county where you lived, if assets exceed the small-estate limit or include real estate | Trust administration by your successor trustee, no court |
| Ongoing | Update when life changes | The same, plus keeping new assets titled in the trust |
| Up-front cost | Lower | Higher: more documents, deeds and funding work |
A trust-based plan costs more at the start because there is more to draft, deeds to prepare and record, and funding work to do. The case for it is made at death. Probate in Cook County means a petition at the Daley Center, letters of office, published notice to creditors, a claims period, an inventory, distribution and a lawyer's time throughout. Personal property of $150,000 or less, excluding registered motor vehicles, can pass by a small estate affidavit without a court (755 ILCS 5/25-1), but real estate cannot, so a house alone forces probate unless it passes by deed, trust or transfer on death instrument. Our probate attorney page describes the process you are deciding whether to pay to avoid.
What moves the price up or down?
- Real estate. Each property means a deed, and each deed means a recording fee. In Cook County the Clerk's fee for a deed (Document Class 1) is $107, effective April 1, 2024. Property in another state means an ancillary probate there unless it is deeded into a trust now.
- Family structure. A second marriage with children from a first, minor children, a child with a disability who needs a supplemental needs trust, a family member who should not manage money, or an heir you intend to leave out all require drafting that a standard package does not include.
- A business. Interests in an LLC or corporation need an assignment, a successor manager and coordination with any buy-sell agreement; see business succession planning.
- Tax exposure. Illinois taxes estates over $4,000,000, and life insurance you own counts. When a couple's combined estate approaches that line, the plan needs a credit-shelter trust or an Illinois QTIP structure, which is tax work on top of drafting work. Our article on the Illinois estate tax explains the threshold.
- Retirement accounts. Large IRAs and 401(k)s raise beneficiary-designation questions with income-tax consequences for the people who inherit them.
- How organized you are. A complete asset list, copies of deeds and statements, and decisions already made about agents and guardians shorten the engagement.
- Updating or starting over. Amending a plan that is sound costs less than replacing one that is not. A plan from another state, or one signed before a marriage, divorce or move, often needs replacing.
What will you pay besides the lawyer's fee?
The hard costs of a plan are small and knowable:
- Recording fees: $107 per deed in Cook County; other counties set their own.
- Notary fees for the signing, if the signing is not at the lawyer's office.
- Certified copies of a death certificate and, later, of letters of office, if probate is needed.
- Appraisals, only when tax planning or a business interest requires a value.
The large cost sits at death, and it is the one you control now. A probate estate pays court costs, publication costs and a lawyer for the months the case is open; a funded trust pays a successor trustee's time and usually some legal advice.
How do you read a quote?
- Ask what is in the flat fee. The list of documents, the signing meeting, the number of deeds, a funding checklist and whether a revision round is included.
- Ask what is hourly, and at what rate. Extra deeds, a supplemental needs trust, a business assignment and tax planning are the usual add-ons.
- Ask how the retainer is held. Ask whether an advance payment goes into the lawyer's client trust account until it is earned, and how any unearned part is refunded. The written fee agreement should answer both.
- Ask what happens after signing. Who retitles the accounts, who records the deed, and when you should come back.
- Ask who does the tax analysis. If the answer is "your accountant," the legal documents and the tax consequences are being designed in two offices.
What are you paying for?
The statutory power-of-attorney forms are printed in the statute, and a will can be two pages. What a lawyer sells is judgment: whether you need a trust at all, how to hold the house, who should serve and in what order, how to treat an IRA so the beneficiary is not pushed into a higher bracket, and whether the plan creates an Illinois estate-tax problem at the second death that it should have solved at the first. Those are tax questions as much as legal ones. Hani H. Khatib, Attorney at Law · CPA · LL.M. (Taxation), designs the documents and the tax consequences together in one engagement, including the income-tax basis step-up at death under Internal Revenue Code section 1014 that decides which assets should be given during life and which should be held.
How do you keep the cost down?
Arrive with the asset list, the deeds and the account statements. Decide on agents, guardians and successor trustees before the first meeting, with a backup for each. Tell the lawyer about the second marriage, the estranged child and the business on day one. And do not buy documents you will not fund; an unfunded trust is a will-based plan that cost more.
