It sounds like the simplest estate plan in the world. You add your daughter’s name to the deed, and when you die the house is already hers. No court, no lawyer, no fuss. People do it at the recorder’s office for the cost of a form. It is also one of the most expensive mistakes we see, and the bill usually does not arrive until after the parent has died and nothing can be undone.
The short answer
Adding a child to your deed gives away a present ownership interest today, not at your death. That exposes the house to your child’s creditors and divorce, costs your family a significant tax break, and cannot be reversed without your child’s signature. In most Illinois situations, a transfer on death instrument accomplishes the same goal with none of those problems.
The rest of this is the “why,” because the reasons are not obvious and nobody at the recorder’s counter is going to explain them.
Problem one: you just gave away half your house
A deed is not a will. When you sign a deed adding your son as a co-owner, he owns part of your house that afternoon. He does not own it “when you pass.” He owns it now.
That means you can no longer sell, refinance, or mortgage the property without his signature. If he says no, the answer is no. If he moves out of state, or stops speaking to you, or has a stroke and cannot sign, you have a problem that takes a court to solve. Parents who do this and later need to sell the house to pay for care often discover the trap at the worst possible moment.
Problem two: his creditors are now your creditors
This is the one that surprises people most. Once your child is on the deed, his share of your house is an asset that his problems can reach.
In Illinois, a money judgment becomes a lien on real estate when a transcript or memorandum of the judgment is recorded in the county where the property sits, under 735 ILCS 5/12-101, and that lien can run for seven years before it has to be revived. A credit card judgment against your son, a hospital bill, a business that failed, or a divorce in which his interest gets counted as a marital asset can all attach to the home you have lived in for forty years. You did nothing wrong. You just handed a creditor a target.
Problem three: the deed may not do what you think it does
Here is a wrinkle that catches even careful people. Illinois does not presume survivorship. Under 765 ILCS 1005/1, no estate in joint tenancy exists unless the deed “expressly” declares that the property passes not in tenancy in common but in joint tenancy. Leave that language out, and the law treats the co-owners as tenants in common.
The practical difference is total. In joint tenancy, your share passes to the survivor automatically. In tenancy in common, it does not. Your half goes through your estate, which is the exact court process you were trying to avoid, and now your child owns half a house with your other heirs. A generic form deed downloaded from the internet gets this wrong regularly.
Problem four: the tax break your family loses
This is the quiet one, and it is often the biggest number on the page.
When someone inherits property at death, the basis is generally reset to the fair market value on the date of death. The IRS states the rule plainly in Publication 551: the basis of inherited property is generally the fair market value at the date of the individual’s death. When property is given away during life, the recipient generally takes the donor’s own adjusted basis instead. That is called carryover basis, and it carries the gain along with it.
Run the numbers on a real southern Illinois house. Say you bought it in 1985 for $40,000 and it is worth $190,000 today. If your daughter inherits it, her basis is roughly $190,000, and selling it soon after produces little or no taxable gain. If you added her to the deed years ago, her share carries your old basis, and the same sale can generate tens of thousands of dollars of taxable gain that the family never had to pay. Nothing about waiting until death costs you anything. It just preserves the step-up.
There is a paperwork consequence too. Adding a co-owner is a gift. Once the value of the interest transferred exceeds the annual exclusion, which the IRS puts at $19,000 per recipient for 2026, a federal gift tax return is due for that year. Most families owe no tax. Most families also never file the return, because nobody told them.
What to do instead
For the majority of Illinois homeowners, the tool that does what people actually want is a transfer on death instrument, usually called a TODI. It is authorized by the Real Property Transfer on Death Instrument Act, 755 ILCS 27, and it is no longer limited to residential property.
A TODI is recorded now and takes effect at your death. Until then you own the property outright. You can sell it, mortgage it, or revoke the instrument, and you do not need anyone’s permission. Your child’s creditors have nothing to reach, because your child owns nothing yet. And because the transfer happens at death, the basis step-up survives.
It is not right for everyone. A TODI does not help with a blended family that needs conditions, it does not manage property for a minor, and it does nothing about who makes decisions if you become unable to. Those are jobs for a will, a trust, or a power of attorney. But as a replacement for “just put her name on the deed,” it wins on every point that matters.
When adding someone to a deed is actually fine
There are real situations where a co-owner belongs on the title. A spouse. A child who is genuinely buying in and going on the mortgage. A sibling who paid half the purchase price. A property being moved into a trust or an entity as part of a plan. If you and your child are truly buying a place together, you should both be on the deed, and the question is simply which form of co-ownership to use.
The problem is not co-ownership. The problem is using a deed as a substitute for an estate plan.
Frequently asked questions
Can I take my child’s name back off the deed?
Only if your child signs a deed transferring the interest back to you. Once recorded, that interest belongs to them, and you cannot undo it on your own. If they refuse, are divorcing, are in bankruptcy, or lack capacity to sign, removing them may take a court proceeding.
Does adding a child to my deed avoid probate?
Only if the deed expressly creates a joint tenancy with right of survivorship. Illinois law defaults to tenancy in common when that language is missing, which means your share still goes through probate. A recorded transfer on death instrument avoids probate for the property without giving up ownership now.
Will a transfer on death instrument protect the house from a nursing home?
No, and be careful of anyone who says otherwise. A TODI controls who receives the property at death. It does not shield the property from long term care costs or from estate recovery. Asset protection for long term care is a separate analysis with its own rules and timelines.
What does it cost to fix a deed that was already changed?
It depends on what the old deed says and who has to sign. A cooperative family often needs one corrective deed and a title search to confirm nothing attached in the meantime. Ask us for a number before you commit. You should get a figure, not a runaround.
Get the deed right the first time
Deeds are short documents where small wording carries large consequences, and the mistakes tend to surface years later when the person who signed is no longer around to explain what they meant. If you are thinking about putting a child on your deed, spend an hour with us first.
Olson & Reeves co-owns Mt. Vernon Title Company, so the deed drafting, the title search that confirms nothing is already attached to your property, and the recording all happen in one office rather than across town.
