Key concepts
The vocabulary you'll hear from attorneys, court clerks, and title companies — in plain English.
Letters Testamentary vs. Letters of Administration
“Letters” is the court document that gives someone the legal authority to handle an estate. No one can sell an inherited house until the court has issued them.
Mo. Rev. Stat. §§ 473.050, 473.080
“Letters” is the court’s formal grant of authority to the person handling an estate. If there’s a valid will and it names an executor, that person receives Letters Testamentary. If there’s no will — or the will doesn’t name anyone who can serve — the court appoints an administrator and issues Letters of Administration. Either document gives the same practical power: the legal authority to act on behalf of the estate.
Why this matters when a house is involved: no one can sign a deed until the court has issued letters. Title companies will ask for a certified copy, usually dated within the last 30–60 days, to confirm the personal representative is still in office. If a family member tells you “we’re handling Mom’s estate” but they don’t have letters in hand, the estate isn’t legally open yet.
There’s no meaningful difference in how real property is transferred once letters are issued — “executor” and “administrator” just describe how the person got the job. Everything downstream (selling, paying creditors, distributing proceeds) works the same way.

Independent vs. Supervised Administration
Missouri runs probate two ways: independent (faster, fewer court hoops) or supervised (the judge approves major decisions, including real estate sales). Which track you’re on can change the timeline by months.
Mo. Rev. Stat. §§ 473.780, 473.810, 473.813
Missouri has two tracks for running a probate estate. Under supervised administration, the personal representative has to get the court’s permission for major decisions — including selling real estate. That means a petition, a hearing, and a formal order of sale. Under independent administration, the PR has the same core powers but doesn’t need court approval for most routine acts. Real estate can generally be sold without a separate trip to court.
Most wills specifically authorize independent administration, and that’s the faster path. If the will is silent, or there’s no will at all, the estate can still be run as independent if all the heirs consent in writing. Absent that, Missouri defaults to supervised.
For a family trying to settle things and sell an inherited home, knowing which track you’re on usually changes the timeline by months. Supervised sales also come with an appraisal-linked minimum price and the risk of a competing “upset bid” at confirmation. Independent sales avoid both. If you’re not sure which track your estate is on, ask the attorney — or we can help you figure it out before you make plans.

Small Estate Affidavit
A simplified procedure for smaller estates that skips full probate. It’s often the fastest way to convey an inherited house — especially when a mortgage brings the equity below Missouri’s threshold.
Mo. Rev. Stat. § 473.097
Missouri has a simplified path for smaller estates: an affidavit procedure that lets distributees collect assets without opening a full supervised estate. Historically the threshold has been $40,000 in total estate value (after liens and exempt property), though thresholds are revised from time to time — it’s always worth checking the current figure at revisor.mo.gov.
One important nuance for real estate: mortgage balance is netted out of the valuation. A $180,000 house with a $160,000 mortgage has $20,000 of equity and can potentially qualify, even though the gross value is well over the threshold. A $50,000 house with no mortgage won’t qualify if there’s additional estate value that pushes past the ceiling — it’s the total that matters, not the single asset.
The affidavit can be filed 30 days after death, after publication of a notice to creditors, and with a bond equal to the estate value. It’s the fastest way to convey a house when the numbers fit. Title insurers tend to be more cautious about small-estate transfers than letters-based ones — expect some extra paperwork and, sometimes, extra indemnity requirements from the title company.

Beneficiary Deeds (Transfer-on-Death)
A recorded deed that passes real estate directly to a named beneficiary the moment the owner dies — completely outside probate. The catch: it has to be recorded before death, or it does nothing.
Mo. Rev. Stat. §§ 461.025–461.081
A Missouri beneficiary deed is a simple estate-planning document that lets an owner name someone to inherit real property automatically at death. While the owner is alive, nothing changes — they keep full control, can sell or refinance, and can revoke or change the deed at any time. At the moment of death, ownership transfers to the named beneficiary by operation of law, completely outside probate.
There’s one requirement that trips people up: the beneficiary deed must be recorded with the county recorder of deeds before the owner dies. A signed but unrecorded beneficiary deed is legally ineffective in Missouri. This catches families off guard more often than you’d think — a deed drafted by an attorney, tucked into a file drawer, and never taken to the recorder’s office does nothing.
If you’re looking at an inherited house and there’s a recorded beneficiary deed naming you, the good news is the property may never have been part of the probate estate at all. You can usually move forward with a sale much faster because you’re selling as the direct owner, not as a personal representative.

Intestate Succession
When someone dies without a will, Missouri’s statute decides who inherits. Every heir on that list has to sign the deed when selling an inherited home — miss one and title is clouded.
Mo. Rev. Stat. § 474.010
When someone dies in Missouri without a will, the state’s intestate succession rules decide who inherits. The two most common patterns: if there’s a surviving spouse and the children are all from that marriage, the spouse takes the first $20,000 plus half of the remaining estate, and the kids split the other half equally. If any of the children are from a prior relationship, the spouse’s preference drops out — spouse takes half, children take half. A spouse with no children generally takes the entire estate.
If there’s no spouse and no children, Missouri walks outward through the family tree: parents, then siblings, then grandparents and their descendants, then great-grandparents. At the far end, if no heirs can be found, the property escheats to the State of Missouri.
The practical implication for selling an inherited house: every heir under § 474.010 is a necessary grantor on the deed. If a decedent left a spouse and three adult children from a prior marriage, you need a deed signed by all four — miss one and title is clouded. That’s why a determination of heirship is often the first step for families dealing with an older, never-opened estate.
This information is general and varies by estate. Consult a probate attorney for your specific situation.
What a title company needs to close
Title companies won’t insure a probate sale until they see a specific paper trail: certified letters, authority to sell, proof creditors were notified, and a properly drafted PR’s deed.
Based on Missouri title underwriting standards
When an estate sells a house, the title company has to build a paper trail that proves the seller actually has the authority to transfer clean title. At a minimum, they’ll ask for certified letters (dated within 30–60 days of closing, so they know the PR is still in office), evidence that the estate is in independent administration or a court order specifically authorizing the sale, and a Personal Representative’s deed with the proper statutory recitals — not a standard warranty deed.
They’ll also want proof that notice to creditors was published, that the six-month claim period has run (or indemnity if it hasn’t), a certified death certificate, and an affidavit of heirship or the filed inventory showing who the heirs are. On the property side: a title search run through the decedent’s name and any common variations, release or payoff arrangements for any mortgages and liens, and proof that real estate taxes are paid through closing.
One practical note: not every title company is comfortable with probate work. Some love it and do it daily; others quietly prefer to send it elsewhere. If you’re selling an inherited home, it’s worth asking your attorney (or us) which local title companies actively handle estate sales — it can save weeks of back-and-forth.

Tax implications — step-up in basis explained
The IRS resets the tax “cost” of inherited property to its fair market value on the date of death. You’re only taxed on gains since then — not on decades of appreciation before.
IRC § 1014
This is the single most common source of confusion for families selling inherited property, and the one that most often leads people to expect a giant tax bill that isn’t actually coming. Federal law resets the tax “cost” of inherited property to its fair market value on the date of death. The decedent’s original purchase price doesn’t matter. That reset is called a step-up in basis.
Here’s the example that makes it click: say your parent bought the house in 1975 for $50,000. They pass away, and the house is worth $200,000 at that moment. Six months later you sell it for $220,000. Your taxable gain isn’t $170,000 — it’s $20,000. The $150,000 of appreciation that happened during your parent’s lifetime is wiped clean. You’re only taxed on what happened after the date of death.
A few more things worth knowing: inherited property is automatically treated as long-term capital gains, regardless of how long you hold it. Missouri has no state estate tax and no state inheritance tax — this is strictly a federal question. Federal estate tax only applies to estates over roughly $13.6 million, so almost no estate we see comes anywhere near owing it. And of course we aren’t tax advisors — before you act on any of this, confirm the numbers with a CPA.

Showing 15 of 57 terms
Abatement
Mo. Rev. Stat. § 473.367
The reduction or elimination of bequests under a will when the estate lacks enough assets to pay all debts and distributions. Claims are paid in statutory priority under § 473.367, and the remaining bequests are reduced proportionally.
Ademption
The failure of a specific bequest in a will because the gifted property is no longer part of the estate at the time of death — for example, the decedent sold the car that was left to a nephew. The nephew generally takes nothing in place of it.
Administrator
Mo. Rev. Stat. § 473.017
The person appointed by the probate court to manage an estate where there is no will or where the named executor is unable to serve. The administrator receives Letters of Administration as proof of authority.
Affidavit of Heirship
A sworn statement by a disinterested third party identifying the decedent's heirs, sometimes accepted by title companies in limited cases. It is not a court order and carries less weight than a § 473.663 determination of heirship.
Ancillary Probate
A secondary probate proceeding opened in Missouri when an out-of-state decedent owned Missouri real property. The main estate runs in the state of domicile; the ancillary estate handles the Missouri real estate under Chapter 473.
Beneficiary
A person designated to receive property under a will, trust, beneficiary deed, or payable-on-death account. Unlike an heir, a beneficiary receives because an instrument names them, not because the law defaults to them.
Beneficiary Deed
Mo. Rev. Stat. § 461.025
A Missouri recorded deed under § 461.025 designating a grantee who takes the property automatically at the owner's death, without probate. To be valid it must be signed, notarized, and recorded with the county recorder of deeds before the owner's death.
Codicil
A formally executed amendment or supplement to an existing will. A codicil must meet the same execution requirements as a will and is read together with the original will as a single testamentary plan.
Creditor Claim Period
Mo. Rev. Stat. § 473.360
The six-month window from first publication of notice to creditors during which unsecured creditors must file claims under § 473.360 or be forever barred. Title companies often want this period to close before insuring an estate sale, or will require indemnity.
Determination of Heirship
Mo. Rev. Stat. § 473.663
A court proceeding under § 473.663 to formally establish a decedent's legal heirs, used when the one-year window to open a regular estate has expired or when the identity of heirs is disputed. The resulting court order clears title for the heirs.
Devisee
A person who receives real property under a will. Historically distinguished from a legatee (who receives personal property), though modern Missouri practice often uses the terms interchangeably.
Domicile
Mo. Rev. Stat. § 473.010
A person's permanent legal home — the state and county they intend to return to. Under § 473.010, probate venue is the county of the decedent's domicile at death, or any county where a nonresident left property.
Elective Share
Mo. Rev. Stat. § 474.160
The surviving spouse's statutory right under §§ 474.160–474.290 to elect against the will and take one-third of the estate (if descendants survive) or one-half (if no descendants). The election must be filed within a statutory window after the will contest period.
Escheat
Mo. Rev. Stat. § 470.010
The passing of property to the State of Missouri under § 470.010 et seq. when a decedent dies without identifiable heirs under § 474.010. Rare in practice because intestate succession extends to fairly remote relatives.
Executor
Mo. Rev. Stat. § 473.017
The person named in a will to administer the estate, appointed and empowered by the probate court through issuance of Letters Testamentary. An executor is a type of personal representative.
