Illinois Grandparents Raising Grandchildren: Estate Planning Guide
What Happened
National Grandparents Day, observed on September 13, 2026, prompted Illinois estate planning attorneys to highlight a growing and often overlooked planning gap: grandparents who serve as primary caregivers for grandchildren frequently lack the legal documents needed to protect those children when they die. An analysis published by Estate and Probate Legal Group in Oak Brook, Illinois, outlines the cascading legal crises that can follow a grandparent caregiver's death when no formal estate plan exists.
The piece draws attention to the dual nature of the crisis a family faces in this situation. When a grandparent who has been raising a grandchild dies without a plan, the family confronts two simultaneous emergencies: a caregiving crisis over who holds legal authority to care for the child, and an estate crisis over who controls the grandparent's property, home, and financial accounts. These two crises unfold through separate legal processes and do not resolve each other automatically.
The analysis focuses specifically on Illinois families and covers the intersection of intestacy law, probate administration, guardianship proceedings, and trust planning. It identifies seven questions grandparent caregivers need to answer now, ranging from who currently holds legal authority over the grandchild to whether beneficiary designations on life insurance and retirement accounts align with the grandparent's broader estate plan. The article was published in the context of Illinois families in DuPage, Cook, and Kane Counties, where the firm serves clients.
What It Means
For Illinois grandparents raising grandchildren, the stakes of dying without a plan extend far beyond the distribution of property. Illinois intestacy law distributes probate assets based on family relationships, and those relationships do not always reflect the caregiving reality. A grandchild who lives full time with a grandparent and depends on that grandparent for every aspect of daily life may receive nothing — or far less than the grandparent assumed — if the grandchild's parent is still living. The distribution follows the legal family tree, not the emotional or practical one. Grandparents who rely on the assumption that a grandchild will naturally inherit the bulk of the estate take a significant legal risk.
The probate process itself adds another layer of complexity. Illinois probate typically runs 9 months to 14 months, with a creditor claim period of 6 months755 ILCS 5/18-3 (claim date not less than 6 months from first publication, or 3 months from mailing, whichever is later); 5/18-12(b) (2-year outer bar from death)Verified Sep 8, 2026View source. Court filing fees begin at $384705 ILCS 105/27.1b(a)(2) (Clerks of Courts Act, as last amended by P.A. 104-468, eff. 7-1-26); 705 ILCS 105/27.3f(c)(1)Verified Sep 8, 2026, and attorney fees in Illinois run on a reasonable compensation standard, typically ranging from 1.9%755 ILCS 5/27-2 (reasonable compensation; no statutory percentage)Verified Sep 8, 2026View source to 3%755 ILCS 5/27-2 (reasonable compensation; no statutory percentage)Verified Sep 8, 2026View source of the estate. Illinois also requires executors to post a surety bond, though a properly drafted will can waive that requirement. During this entire administration period, questions about the family home — where the grandchild may attend school, sleep, and maintain friendships — remain unresolved. Other heirs may assert inheritance rights to the property. Creditor claims may reduce the estate. The house that represented stability for the child becomes an asset subject to court administration. Our guide to the cost of probate in Illinois provides a detailed breakdown of what families can expect to pay through the process.
A revocable living trust addresses many of these vulnerabilities directly. Assets held in trust do not pass through probate, which means the family home, financial accounts, and other trust-funded property transfer to named beneficiaries without court involvement, delay, or public disclosure. A trust also allows a grandparent to specify exactly how and when inherited assets reach a grandchild — naming a trustee to manage funds, setting distribution standards tied to education, housing, or healthcare, and extending oversight well beyond the age at which the grandchild could otherwise receive assets outright. Illinois allows Transfer on Death Instruments for real property, which can keep a home out of probate, but a trust offers broader control over how that property is managed for a minor beneficiary after the transfer. Grandparents raising grandchildren also need to coordinate beneficiary designations on life insurance and retirement accounts with their overall plan, since those assets pass outside the will entirely and naming a minor child directly as beneficiary can trigger additional legal proceedings to manage the funds. Illinois does recognize transfer-on-death deeds for real property, giving grandparents an additional non-probate transfer option for the family home. For families weighing these options, our article on avoiding probate with a trust explains the core mechanics in plain language.
Illinois wills require 2755 ILCS 5/4-3Verified Sep 16, 2026View source witnesses and a minimum age of 18 years755 ILCS 5/4-3Verified Sep 16, 2026View source for the testator. Notarization is not required for the will itself, though a self-proving affidavit — which streamlines probate admission — does require additional formalities. Illinois does not recognize handwritten wills, meaning an informal document prepared without witnesses carries no legal weight at probate. For grandparents who have expressed wishes verbally or through informal notes, this point matters enormously: a verbal understanding with a family member about who will raise the grandchild or receive the house carries no legal authority when the probate court applies Illinois law. The court applies the documents that exist, not the conversations that occurred. Illinois also provides a surviving spouse with an elective share of 33%755 ILCS 5/2-8Verified Sep 15, 2026View source of the estate, a factor relevant when one grandparent survives the other and the estate plan needs to account for the survivor's rights alongside the grandchild's needs.
Illinois imposes a state estate tax with an exemption of $4,000,00035 ILCS 405/2Verified Sep 15, 2026View source, which sits well below the federal exemption of $15,000,00026 USC 2001(c), 2010; P.L. 119-21 §70106Verified Sep 15, 2026View source. Grandparents with homes, retirement accounts, and life insurance whose combined value approaches or exceeds $4,000,00035 ILCS 405/2Verified Sep 15, 2026View source face potential Illinois estate tax exposure that a trust structure may help address. Illinois is one of only 12 states that imposes its own estate tax, making state-level planning particularly important for Illinois families. Grandparents in this situation benefit from coordinating with an estate tax planning attorney who understands both the federal and Illinois tax landscapes.
Context from SimplyTrust
The challenges facing grandparent caregivers in Illinois illustrate why estate planning requires more than a basic will. The family home, the question of who manages a minor child's inheritance, the alignment of beneficiary designations, and the selection of backup trustees and guardians all require deliberate, coordinated planning. Our guide to estate planning for grandchildren walks through the specific considerations grandparents face when they want to provide lasting financial support for a grandchild, including trust structures that extend beyond the age of majority. For grandparents who want to understand the full scope of what estate planning involves, our glossary of estate planning terms provides accessible definitions for concepts like intestacy, probate, trustee, and beneficiary designation that appear throughout the planning process.
For grandparents who want to understand whether their estate would require probate and what that process would cost their family, the free probate cost calculator provides a state-specific estimate based on estate size. Grandparents raising grandchildren often carry significant assets — a home, retirement accounts, and life insurance — that together can produce a substantial probate estate if not structured carefully. Understanding the potential cost and timeline of probate is a practical starting point for evaluating whether a trust-based plan makes sense for a particular family's circumstances.
