Who Can Authorize a Cremation in Illinois? The Next-of-Kin Order Explained

By Milos Djordjevic, Funeral Director and Owner, Caring Cremations

In Illinois, the law decides who can authorize a cremation. Your loved one's own written wishes come first. If there are none, the right passes in a set order: a designated agent, the executor, the spouse, the adult children, the parents, then other next of kin.

The order of priority under Illinois law

If your loved one did not leave written directions, the Illinois Disposition of Remains Act gives the right to decide in this order. The right belongs to the first adult (18 or older) on the list who is competent to decide.

1. A designated agent. Someone your loved one named in a signed, notarized form to make this decision.
2. The executor, acting on instructions in the will.
3. The surviving spouse. A civil union partner has the same right as a spouse.
4. The adult children. One child if there is only one, or a majority of the adult children.
5. The parents.
6. The next closest adult relatives, by degree of kinship. This can include brothers and sisters, grandchildren and grandparents. A majority of that group decides.
7. A religious, civic or fraternal organization willing to take legal and financial responsibility.
8. A public official, such as the county medical examiner, when no one else is available.
9. Any other willing person who accepts legal and financial responsibility.

There is one special case. When a service member dies on active duty, the person named on their military emergency data form (DD Form 93) decides.

The Illinois Crematory Regulation Act uses this same order for the person who signs the cremation authorization.

When your loved one left written wishes

Written directions from the person who died come before anyone on the list. Illinois recognizes several kinds:

• Appointment of Agent to Control Disposition of Remains. This is the state's form for naming one person to decide. Both people sign it, and your loved one's signature must be notarized. 755 ILCS 65/15
• A health care power of attorney. In Illinois, this power can continue after death for decisions about remains. The standard state form covers cremation and burial unless your loved one limited it. 755 ILCS 45/4-3
• A pre-need cremation authorization. A person can sign their own cremation authorization in advance. The crematory can then proceed without anyone else's signature. 410 ILCS 18/65
• A will or a prepaid funeral contract. Directions in these are binding, as far as the money available allows. 755 ILCS 65/40

If your loved one left written instructions against cremation, no one can authorize it.

When there are several children or relatives

When the right belongs to a group, such as three adult children, a majority of that group decides. All of them do not have to sign.

Fewer than half may go ahead if two things are true. They made reasonable efforts to tell the others. And they know of no objection from more than half of the group.

When you call us, let us know about any brothers, sisters or other relatives at the same level. That way the right people sign before the cremation.

When family members disagree or can't be reached

Illinois has no deadline that takes the right away from a relative who refuses to act or can't be found. The law speaks to two situations:

• Parents. If one parent can't be located after reasonable efforts, the other parent may decide alone.
• A dispute. Any family member can ask a court to decide. The law directs the court to rule within 30 days of the filing. 755 ILCS 65/50

A majority of children or relatives may legally go ahead over one person's objection. But a crematory that knows about a dispute may wait for a court order before it proceeds, and it is protected if it does. 410 ILCS 18/45

If you expect a disagreement, tell us early. It is far easier to talk it through before the paperwork is signed.

Estranged spouses, ex-spouses and partners

Illinois law has no exception for estrangement. A husband or wife who is separated but not divorced is still the spouse, and still comes before the children. A protective order does not change that either.

• An ex-spouse has no right once the divorce is final.
• An unmarried partner has no right under the list, however long you were together. Your loved one could have named them with the designated agent form.
• A civil union partner has the same right as a spouse. 750 ILCS 75/20

A person loses the right only if they are charged with murder or voluntary manslaughter in connection with the death, and the funeral home knows of the charge. The right then passes to the next person on the list. 755 ILCS 65/20

If you are worried that the wrong person would decide for you, the designated agent form is the way to prevent it.

When there is no family

If no relative can be found or will act, the right passes to a willing organization, then to a public official, then to any willing person who accepts responsibility.

In Cook County, the Medical Examiner’s indigent cremation program handles people no one claims. By county policy, it holds the body for 30 days so family can come forward and arrange funding. The program offers cremation only, and family can retrieve the cremated remains within a year.

If you learn that a relative is on the county's unclaimed persons list, contact the Medical Examiner's family services team at meofamilyservices@cookcountyil.gov.

Signing the cremation authorization

The person with the right signs a cremation authorization form. A few rules apply to every cremation in Illinois:

• No notary needed. The form can be signed on paper or electronically, and a funeral director signs as witness. 410 ILCS 18/20
• The signer vouches for the facts. By signing, you confirm that the information is true and that you have the right to authorize. You are personally responsible if it is not.
• A 24-hour wait. Illinois does not allow cremation within 24 hours of death, except in rare cases such as certain religious requirements.
• A county permit. The county medical examiner or coroner must issue a cremation permit first. In Cook County, see our guide to death certificates and permits.

Most cremations at Caring Cremations are completed within 5 to 10 business days, depending on permits and the doctor's signature on the death certificate.

How to make your own choice binding

You can spare your family these questions by putting your wishes in writing now:

1. Name your decision-maker with the Illinois designated agent form, and have your signature notarized. This matters most if you are separated, unmarried, or estranged from close family.
2. Sign a pre-need cremation authorization, so no one else has to sign later.
3. Tell your family where your papers are and what you chose.

You can pre-plan online with Caring Cremations, or call us at (773) 866-2273 and we'll walk you through the forms. If a death has just happened, see what to do when someone dies at home, or learn about our cremation services in Chicago.

Common questions

Do all of my brothers and sisters have to sign?

No. When siblings hold the right, a majority of them decides. Fewer than half can act if they tried to reach the others and know of no majority objection.

Can my partner authorize the cremation if we weren't married?

Not under the standard order, unless you were in a civil union. Your partner can decide only if you named them on the designated agent form or in a health care power of attorney.

My father and his wife were separated. Who decides?

His wife does, as long as they were still legally married. Separation does not remove a spouse’s right in Illinois.

Can I sign if I live out of state?

Yes. The cremation authorization can be signed electronically, so you don't need to travel to Chicago.

What if one of the children objects?

The majority may go ahead, but a crematory may choose to wait for a court order. Any family member can ask a court to decide, and the court is directed to rule within 30 days.

Does a grandchild have any say?

Only if there is no spouse, no adult child and no parent who can act. Then grandchildren share the right with other relatives at the same level of kinship.
