Planning Ahead

A useful estate plan starts with four questions: what do you own, how is it titled, who should receive it, and who should be able to act if you cannot? The answer is usually not one document—it is how the documents, titles and beneficiary designations work together.

Do I Need a Will or a Trust?

It depends on your assets, family and goals. A will can direct probate property, nominate an executor and address certain family matters. A revocable living trust can hold and manage property during life and direct how trust property is handled after death. Many plans use both.

What Makes a Will Valid in Illinois?

Illinois generally requires a will to be in writing, signed by the testator—or by another person in the testator’s presence and at the testator’s direction—and attested in the testator’s presence by at least two credible witnesses. Capacity and signing formalities matter.

A clear statement of wishes is not enough if execution requirements are not satisfied.

Does a Will Avoid Probate?

No. A will tells the probate court how probate property should be handled; it does not itself remove property from probate. Whether probate is needed depends on the assets, their value, ownership and beneficiary arrangements.

What Does a Revocable Living Trust Do?

A revocable trust can manage property during life and direct distribution after death. It only controls property that is properly transferred to it or otherwise made subject to it. A trust that is never coordinated with actual ownership may not accomplish the intended result.

Not sure whether your plan fits your assets?
Attorney Wendi can review your current will, trust, deeds and beneficiary arrangements together rather than treating each document separately.

What Property Can Pass Outside Probate?

Depending on the asset and documentation, property can pass through trusts, beneficiary designations, payable-on-death or transfer-on-death arrangements, certain joint ownership and an effective transfer-on-death instrument for Illinois real estate.

These tools operate together. A beneficiary designation or ownership arrangement can control an asset even if the will says something different.

Do Beneficiary Designations Override a Will?

Generally, a valid beneficiary designation controls that asset rather than the will. Retirement accounts, life insurance, bank and investment accounts can therefore affect how the overall estate plan works.

What Other Documents May Be Important?

Depending on the circumstances, an estate plan may include powers of attorney for property and health care, trust documents, beneficiary designations and real-estate transfer planning. A will governs after death; powers of attorney can matter during life if illness or incapacity prevents someone from handling financial or medical decisions personally.

Does a House Belong in a Trust?

Sometimes, but not automatically. The answer depends on title, family goals, mortgage issues, taxes, other assets and whether another transfer method may fit better. The deed and estate plan need to be considered together.

Does a Revocable Trust Protect Assets From Nursing-Home Costs or Creditors?

A standard revocable living trust does not automatically create Medicaid eligibility or general creditor protection. Long-term-care and asset-protection planning involve different rules.

When Is an Estate Plan Commonly Revisited?

Estate plans are commonly revisited after major life or financial changes such as marriage, divorce, birth or adoption, death of a beneficiary or fiduciary, a significant asset change, relocation or a change in goals or law. Periodic review can also identify whether beneficiary forms and account ownership still match the plan.

What Happens If I Die Without a Will?

Illinois intestacy law determines who receives probate property. If a person dies leaving both a spouse and descendants, Illinois generally allocates one-half to the spouse and one-half to descendants, per stirpes.

Quick Answers

Common Illinois Estate Questions

General information only. The documents, assets and facts of each estate matter.

Do I need a will or a trust in Illinois?

It depends on your assets, family circumstances, goals and how property is titled. A will and a revocable living trust serve different purposes, and many estate plans use both.

What makes a will valid in Illinois?

Illinois generally requires a will to be in writing, signed by the testator or by someone in the testator's presence and at the testator's direction, and attested in the testator's presence by at least two credible witnesses.

Does a will avoid probate in Illinois?

No. A will directs the disposition of probate property and can nominate an executor, but property controlled by the will generally still passes through probate when probate administration is required.

What does a revocable living trust do?

A revocable living trust can hold and manage property during life and direct distribution after death. Property properly transferred to the trust can often be administered outside probate.

Do beneficiary designations override a will?

Assets with valid beneficiary or transfer-on-death designations generally pass according to those designations rather than under the will, subject to the governing account or instrument and applicable law.

What other documents are commonly included in an Illinois estate plan?

Depending on the person's needs, an estate plan may include powers of attorney for property and health care, beneficiary designations, trust documents, transfer-on-death arrangements and other planning documents.
