You’ve built a life with someone you love — you may share a home, finances, memories, and maybe even kids — but without a legal marriage, Illinois law doesn’t automatically recognize your relationship. If something happens to you, your partner could be left without rights to your property, your finances, or even a say in your medical care.
This guide explains the extra risks unmarried couples face, the key documents that close those gaps, and how Family Wealth & Legacy Legal Solutions (FWLLS) helps you put a plan in place that actually works when your family needs it most.
Why Illinois Law Doesn’t Protect Unmarried Partners by Default
When a married person becomes ill or dies, the law grants the spouse automatic rights and gives them the highest priority (755 ILCS 55/2-1). Unmarried partners don’t receive those rights and will have no authority to act on your behalf, unless you grant them those rights through specific legal documents.
Without an estate plan:
- Your partner can’t access your accounts to pay bills if you’re incapacitated.
- Hospitals will turn to your next of kin — not your partner — regarding your medical decisions and care.
- Your property passes to biological or legal relatives, not your partner, if you die without a will or trust.
Illinois law is particularly clear on this point: common-law marriage is not recognized unless you’ve attained that status within another state. Only a common-law marriage validly established in another state may be recognized here, and proving that can be complicated. Living together — even for decades — does not create marital rights or any legal presumption in the State of Illinois.
What Happens If an Unmarried Illinoisan Dies Without a Will
If you die unmarried and without a will, you are said to have died “intestate,” meaning your estate is distributed under Illinois’s intestate succession statute, found in Section 2-1 of the Illinois Probate Act of 1975 (755 ILCS 5/2-1).
Under that law, the order of inheritance is:
- If you have children: your estate passes entirely to your descendants, per stirpes.
- If you have no descendants but parents and/or siblings: your estate is divided between them in equal parts (with detailed rules if one parent is deceased).
- If you have no immediate family: it continues to grandparents and their descendants.
- If no heirs exist: your property eventually “escheats,” meaning real estate may pass to the county and personal property to the State of Illinois.
Nowhere in the statute are unmarried partners mentioned. That means your partner — no matter how long you’ve been together — inherits nothing unless you create a valid will, trust, or beneficiary designation naming them.
Essential Legal Tools Every Unmarried Couple Should Have
1. Health Care Documents
Without proper documents, hospitals must look to your next of kin for medical decisions.
A Health Care Power of Attorney under 755 ILCS 45/4-1 allows you to designate your partner to make healthcare choices on your behalf. Pair it with a Living Will or Advance Directive (authorized by 755 ILCS 35) to express your end-of-life wishes, and add a HIPAA Authorization so providers can share medical information with your partner.
2. Financial Power of Attorney
A Power of Attorney for Property (755 ILCS 45/3-1) allows your partner to handle financial matters — such as paying bills, managing accounts, or maintaining your home—without requiring a court-appointed guardian if you are incapacitated. Meaning, if you are alive but unable to handle and manage your own financial affairs because of an injury, coma, Alzheimer’s, or dementia, then your loved ones would need to go to court and ask for permission to access your assets and act on your behalf. Just remember, your significant other would not be granted priority to act in this role if there was a dispute.
3. Revocable Living Trust and Will
A Revocable Living Trust (RLT) keeps your affairs private, avoids probate, and gives you control over what happens both during incapacity and after death. You can ensure your partner retains the home, receives support, or shares in certain accounts.
If you rely solely on a Will, your estate must pass through probate, a public and often lengthy court process. Probate is governed by the Illinois Probate Act (755 ILCS 5), and it takes time and can add unnecessary expenses and complications to the process — especially for someone who is not legally related to you.
Additionally, Illinois law allows real estate to transfer outside probate through a Transfer on Death Instrument (TODI), governed by 755 ILCS 27, but this tool must be coordinated carefully with your overall estate plan to avoid conflicts or unintended results.
4. Proper Titling and Beneficiary Designations
Even the best legal documents can fail if the title to your assets and beneficiary designations aren’t dialed in and don’t specifically reflect your intentions. At FWLLS, we help you align the proper form of ownership for your accounts, property, and life insurance policies, so your partner is included and will receive exactly what you intend.
5. Cohabitation Agreement
A cohabitation agreement can serve as both a financial and legal safety net. It outlines each partner’s ownership interests, financial contributions, and rights if the relationship ends or one partner passes away. While not part of traditional estate planning, it does provide an added layer of clarity and protection.
Emotional and Practical Planning That Matters
Estate planning for unmarried couples is primarly focused on protecting your chosen family — not just your assets. It is critical to ensure that you have granted them the legal rights to act on your behalf and specifically provided an inheritance for them because the law does grant them these rights, if the unthinkable happened to you.
At FWLLS, we also help you with other critical tasks to protect your loved ones:
- Build and maintain an Asset Inventory so nothing gets lost or overlooked.
- Record a values and legacy message for your partner.
- Encourage open communication with family members to reduce conflict and confusion later.

Illinois FAQs
Does my partner inherit anything if I die without a will?
No. Under 755 ILCS 5/2-1, unmarried partners are not recognized as heirs.
Are we common-law married if we’ve lived together for years?
No. Illinois abolished common-law marriage in 1905. Only common-law marriages validly created in other states may be recognized here.
Can we protect our home without getting married?
Yes. You have several options, and we would recommend considering a Revocable Living Trust, joint ownership, or a Transfer on Death Instrument under 755 ILCS 27. Each has unique tax and creditor implications.
What if I have children from another relationship?
Your trust can protect your partner’s right to live in the home while ensuring your children ultimately inherit. This is one of the most effective ways to balance blended family dynamics.
