When a husband, wife or long-time co-owner dies, the house is usually the biggest thing left to sort out, and in Greater Hartford and eastern Connecticut it is often a house the two of you bought decades ago. Many surviving spouses are told the house is "already theirs" because the deed said joint tenants with right of survivorship. That is true. It is also why many of them are surprised when, a year or ten years later, a buyer's attorney stops the sale over a Connecticut estate tax lien nobody mentioned. This guide covers what happens to the house when one owner dies, the probate court paperwork that clears the title even when no estate tax is owed, how the sale is taxed, what happens to the mortgage, and how to decide whether to stay or sell. (This is general education, not legal or tax advice. A Connecticut probate attorney and a tax preparer should look at your situation.)
If the deed named you both as joint tenants with right of survivorship, the house passed to you automatically at death, and there is no probate for the house itself. But Connecticut places an unrecorded estate tax lien on real estate when an owner dies, and a buyer's attorney will want it released. You clear it by filing Form CT-706 NT with the probate court, which then issues a certificate of release of lien to record on the town land records. That holds even though, for 2026 deaths, Connecticut estate tax applies only to estates over $15 million. On the tax side, a surviving spouse usually gets a new basis on the late spouse's half and can claim the $500,000 home-sale exclusion if the house is sold within two years of the death. A lender cannot call the mortgage due simply because the house passed to you.
First question: how was the deed titled?
Everything else depends on the words on your recorded deed. You can get a copy from the town clerk's land records in the town where the house sits. Look at how the owners are described:
| How the deed reads | What happened at death | What you need to sell |
|---|---|---|
| Joint tenants with right of survivorship (a "survivorship deed") | The surviving owner became sole owner automatically | A recorded release of the Connecticut estate tax lien, then the survivor signs alone |
| Tenants in common, or no survivorship language | The deceased owner's share passes under the will or intestacy | A probate estate and a fiduciary with authority to sell that share |
| Deceased spouse's name only | The whole house is part of the probate estate | Full probate. See our Connecticut inherited-house and probate guide |
| Owned by a living trust | The successor trustee takes control under the trust | The trustee signs, under the trust's terms |
Most married couples in this market who bought together hold title as joint survivors, so the rest of this guide focuses on that case. If your situation is one of the other rows, the probate guide linked above is the better starting point, and our page on selling an inherited house in Hartford covers the practical side.
The estate tax lien nobody mentions
When someone dies owning an interest in Connecticut real estate, the state holds a lien on that interest for any estate tax that might be due. It is not recorded on the land records, which is why estate attorneys call it an inchoate (hidden) lien. You will not see it on a tax bill. It surfaces when a buyer's attorney runs a title search, finds the death, and finds no recorded release. One Connecticut estate law firm, Cipparone & Zaccaro, has described a client who held a survivorship deed with her husband, sold years after his death, and had the closing held up until the release was obtained.
The fix is straightforward. It just has to be done:
- File Form CT-706 NT, the Connecticut estate tax return for nontaxable estates, with the probate court for the district where your spouse lived. The Department of Revenue Services' instructions say it is due within six months of the date of death, and that every Connecticut resident's estate needs one, not only estates that went through probate. Extensions are available.
- Attach the supporting documents. The instructions list a copy of the death certificate and the recorded deed for any Connecticut real property, along with schedules of the estate's assets.
- The probate judge reviews it. If the estate is under the exemption, the court issues a certificate of release of lien on the real property.
- Record the release on the land records of the town where the house is. That is what clears the title for your buyer.
The tax itself is almost never the issue. For deaths in 2026, DRS says the Connecticut exemption is $15 million (it was $13.99 million for 2025), and property passing to a surviving spouse is generally deductible as well. What catches families out is the paperwork. If the six months came and went years ago, the filing can still be made late. The attorneys in the example above cleared a lien from a death many years earlier.
Selling before the return is filed
You do not always have to finish the CT-706 NT before you can sign a contract. The probate courts publish Form PC-205B, which lets a fiduciary or survivor ask the court to release the estate tax lien, and the separate lien for probate fees, on a specific property being sold, transferred or mortgaged, using estimated figures. It also lets you tell the court that the probate fee will be paid from the sale proceeds. That fee is a real cost even when no probate estate is opened. The DRS instructions explain that probate fees are calculated on the larger of the probate inventory, the Connecticut taxable estate or the federal gross estate, so jointly owned property counts. The portion passing to a surviving spouse is reduced by 50%. Your attorney or the court clerk can tell you what the fee will be.
Spouse, child or sibling: why it matters who the co-owner was
The CT-706 NT does not treat every survivorship deed the same way. Per the DRS instructions:
- Between spouses, 50% of the property's value is reported in the deceased spouse's estate, and the other half is excluded.
- Between non-spouses, such as a parent and adult child or two siblings, 100% of the value is reported unless the estate can show the survivor paid toward the purchase. Then only the deceased owner's proportionate share is included.
This matters for more than the form. The share included in the estate is generally the share that gets a new tax basis, which affects your capital gains when you sell. A parent who added a child to the deed years ago "to avoid probate" may have created a survivorship deed of this second kind, and the paperwork should reflect that.
Capital gains when a surviving spouse sells
Two federal rules work in a surviving spouse's favor. Both are spelled out in IRS Publication 523, Selling Your Home:
- The new basis on your late spouse's half. If you owned the home jointly, the basis of the half your spouse owned resets to its fair market value on the date of death, and your own half keeps its original basis. Your new basis is the total of the two.
- The $500,000 exclusion for two years. A surviving spouse can exclude up to $500,000 of gain, rather than the single-filer $250,000, if the house is sold within two years of the spouse's death, you have not remarried at the time of the sale, and the usual ownership and residence tests are met (your late spouse's time in the house counts toward them).
An illustration with round numbers, not a real sale: a couple bought a house for $180,000, and it was worth $400,000 when one spouse died. The survivor's basis becomes $90,000 for their own half plus $200,000 for the inherited half, or $290,000. Sold at $400,000, the gain is about $110,000, well inside even the single exclusion. The two-year window matters most on a house held for decades, where a lot of appreciation has built up. Connecticut taxes capital gains as ordinary income, so the same gain flows through to your state return. Confirm your own figures with a tax preparer before you choose a closing date.
The mortgage does not come due just because your spouse died
Most mortgages contain a due-on-sale clause, but federal law limits its use after a death. Under 12 U.S.C. §1701j-3(d), on a home with fewer than five units, a lender may not call the loan because of a transfer on the death of a joint tenant, a transfer to a relative resulting from the borrower's death, or a transfer in which the borrower's spouse or children become an owner. In practice, keep making the payments, send the servicer a copy of the death certificate, and ask to be recognized as the successor in interest so they will discuss the account with you. If the loan is a reverse mortgage, the rules are different and the timeline is tighter. Our reverse mortgage guide covers that case.
Staying or selling: questions to ask before you decide
There is no deadline to sell, and nobody should rush a decision in the first months after a death. These are the questions that usually settle it:
- Can one income carry the house? Property taxes, insurance, heating oil or gas, and an older house's repairs were often budgeted for two.
- Who will handle the upkeep? Snow, gutters, a 30-year-old boiler and a roof near the end of its life are a lot to take on alone.
- Is the two-year exclusion window in play? If you have a large gain, the calendar matters.
- Does the house still fit how you live? Stairs to every bedroom, a large yard, distance from family. Our downsizing guide for Greater Hartford covers senior housing options and the Medicaid questions to ask before selling.
If the surviving owner can no longer manage their own affairs, someone else may need legal authority to sell. See our guide to selling a parent's house under a power of attorney or conservatorship.
Your three real options
1. List it with an agent
If the house is in good shape and you have time, listing usually brings the highest price. Expect commissions, showings, repair requests after the inspection, and a buyer whose lender has its own conditions. Start on the lien release early so it is not the reason the closing date slips.
2. Fix it up first, then list
Some updates pay for themselves, and many do not. Our comparison of selling as-is versus renovating walks through which repairs are worth it in this market.
3. Sell as-is for cash
A direct sale suits a survivor who doesn't want to clear out forty years of belongings, manage contractors or keep the house show-ready. You will usually net less than a well-prepared listing, in exchange for a fixed date, no repairs and no buyer financing to fall through. The lien release is still needed, and a buyer's attorney will ask for it either way.
How we help a surviving spouse or co-owner
We buy houses exactly as they stand across Greater Hartford and eastern Connecticut, from Hartford, West Hartford and Manchester to Norwich and the New London County towns around our Taftville office. You can leave behind whatever you don't want to keep, choose a closing date that gives you time to move, and work through your own attorney on the estate tax release and the deed. Title problems are familiar ground for us. One example is a New Britain triplex we closed despite an unreleased mortgage and municipal tax liens.
We will also tell you when we are the wrong answer. If the house is in good condition and you are in no hurry, listing it will probably leave you with more. For the full picture, see how a cash sale works and the questions sellers ask most on our FAQ page.
