Bottom line: Texas does not have a single legal document called a “letter of heirship.” When people search for one, they usually mean one of four things — an Affidavit of Heirship, Letters Testamentary, Letters of Administration, or a court-issued Determination of Heirship. Each does a different job, and which one you need depends on whether the deceased had a will, whether probate is open, and whether you’re trying to sell property that a title company will insure.
Sorting out paperwork after losing someone is hard enough without the legal terminology adding confusion. William Zhang is a probate real estate consultant and the founder of texasprobateprocess.com — he helps Texas executors and heirs navigate the sale of inherited property across all 254 counties. This guide explains the four documents people usually mean when they ask for a “letter of heirship” and routes you to the right one — start with how probate works in Texas if you need the full context.
”Letter of Heirship” Isn’t a Texas Legal Term — Here’s What People Usually Mean
Texas law doesn’t use the phrase “letter of heirship.” What people usually mean is a document that proves who the heirs are and gives them legal authority to deal with inherited property. That proof comes from four different sources depending on the situation:
- Affidavit of Heirship — sworn document signed by witnesses, recorded in deed records; used when there’s no will and no probate
- Letters Testamentary — court document issued to an executor when there is a will and probate is open
- Letters of Administration — court document issued to an administrator when there is no will and probate is open
- Determination of Heirship — formal court order naming the heirs; the upgrade when a title company won’t accept an affidavit
Using the wrong one — or an informal document when a formal one is required — is where things stall.
1. Affidavit of Heirship — When There’s No Will and No Probate
An Affidavit of Heirship is the document most people are looking for when they search for a “letter of heirship.” Two disinterested witnesses — people who knew the deceased but have no financial stake in the estate — sign a sworn statement identifying the heirs and describing the property. You record it in the county deed records where the property is located.
The catch is the seasoning rule. Under Texas Estates Code § 203.001, most title companies won’t treat the affidavit as strong enough to insure until it has been on record for five years. File it today and try to sell to a financed buyer next month, and you’ll likely hit a wall. The affidavit costs $200–$600 plus recording fees — far less than full probate — and works well for simple estates where no one is in a rush to sell.
For everything you need to know about when it works and when it doesn’t, read the Texas Affidavit of Heirship guide.
2. Letters Testamentary — When There’s a Will and Probate Is Open
Letters Testamentary is a one-page document issued by a Texas probate judge that officially certifies you as the executor of an estate. Banks, title companies, and government agencies all require it before they’ll allow you to act on the estate’s behalf — even if you’re named in the will, you have no legal authority without it.
To get Letters Testamentary, you file an application with the probate court in the county where the deceased lived, attach the original will, pay a filing fee, and attend a short hearing. In most Texas counties, the process takes three to six weeks from filing to having Letters in hand. The Letters Testamentary in Texas guide covers every step.
3. Letters of Administration — When There’s No Will and Probate Is Open
When someone dies without a will, a family member petitions the probate court to be appointed as administrator. The court then issues Letters of Administration — functionally identical to Letters Testamentary — authorizing the administrator to sell property, pay debts, and distribute assets.
Whether the court opens an independent or dependent administration makes a significant practical difference. Read Independent vs. Dependent Administration in Texas to understand which path applies.
4. Court-Issued Determination of Heirship — When Title Companies Won’t Accept an Affidavit
A Determination of Heirship is the upgrade path when an Affidavit isn’t strong enough. A judge formally identifies the heirs, an attorney ad litem represents any unknown heirs, and the court order is recorded in the deed records. Title companies accept it without the five-year wait.
The tradeoff: typically $2,000–$5,000 and two to four months. If you need to sell to a financed buyer and your affidavit is too recent, this is usually the right move. A Texas probate attorney can confirm which option fits your county.
Quick Decision Table: Which Document Do You Actually Need?
| Situation | Document Needed | Who Issues It | Typical Cost | Title-Insurance Acceptance |
|---|---|---|---|---|
| Deceased had a will; probate is open | Letters Testamentary | Probate court | $300–$500 filing fee + attorney | Almost always accepted |
| No will; probate is open | Letters of Administration | Probate court | $300–$500 filing fee + attorney | Almost always accepted |
| No will; no probate; filed 5+ years ago | Affidavit of Heirship | Prepared privately; recorded in deed records | $200–$600 + recording fee | Often accepted |
| No will; no probate; filed less than 5 years ago | Affidavit of Heirship | Prepared privately; recorded in deed records | $200–$600 + recording fee | Often rejected or requires underwriter approval |
| No will; affidavit not strong enough for title company | Determination of Heirship | Probate court (formal order) | $2,000–$5,000 | Almost always accepted |
What Title Companies Care About
When you’re trying to sell inherited property in Texas, the title company has to insure the buyer against title defects. They need confidence that you have clear legal authority to sell. If they’re not satisfied with your documentation, they won’t issue title insurance — and most financed buyers can’t close without it.
The practical hierarchy:
- Any court order (Letters Testamentary, Letters of Administration, Determination of Heirship, or muniment of title) is almost always accepted — a judge has already reviewed ownership.
- An Affidavit of Heirship on record five or more years is accepted by many title companies, but not all. The underwriter decides case by case.
- A recent Affidavit of Heirship is frequently rejected for insured transactions. Cash buyers have more flexibility, but you’ll limit who can buy.
Get a copy of your deed records and show them to a title company before you list. They’ll tell you quickly what they need.
When You Don’t Need Any “Letter” at All
Not every inherited property requires a formal heirship document.
Muniment of title: If the deceased left a valid will and had no significant unpaid debts other than a mortgage, Texas allows a simplified court proceeding that transfers property without appointing an executor. It typically takes six to ten weeks and costs $2,000–$3,500.
Small Estate Affidavit: If the entire estate is valued at $75,000 or less (excluding the homestead and exempt property), this simpler court process may be available.
Survivorship deeds and transfer-on-death deeds: If the deceased held property under a joint tenancy with right of survivorship or had a TOD deed in place, the property may transfer automatically without any probate proceeding.
For a broader look at all available shortcuts, Texas Probate Alternatives covers every option in one place.
How to Figure Out Which Document Applies to Your Situation
Work through these questions:
Did the deceased leave a valid will? If yes and probate is open, the executor receives Letters Testamentary. If yes and the estate has no significant debts, muniment of title may be a faster alternative.
No will — is the estate in probate? If yes, the appointed administrator receives Letters of Administration. If no, you’re looking at an Affidavit of Heirship or Determination of Heirship.
Do you need to sell soon to a buyer with a mortgage? If the Affidavit of Heirship was recorded recently, most title companies won’t insure it. A Determination of Heirship (or opening formal probate) gives you court-backed title that any title company will accept.
A title company can evaluate your specific documents at no charge before you list. If you need a second opinion first, a Texas probate attorney can confirm the right path for your county.
Frequently Asked Questions
What’s the difference between a letter of heirship and an affidavit of heirship?
“Letter of heirship” is an informal phrase with no legal meaning in Texas. “Affidavit of Heirship” is the actual document — a sworn statement signed by witnesses and recorded in county deed records. When someone asks for a “letter of heirship,” they usually mean the affidavit.
Do I need a court order to inherit Texas property?
Not always. An Affidavit of Heirship can establish ownership without court involvement, but it has the five-year seasoning rule and title company risk. A court order — probate, muniment of title, or Determination of Heirship — gives you cleaner, more widely accepted title.
Can I sell a Texas house with just an affidavit of heirship?
It depends on when the affidavit was recorded and whether the buyer needs a mortgage. An affidavit on record five or more years is often accepted. A recent affidavit is frequently rejected. Cash buyers have more flexibility. See the full Affidavit of Heirship guide for details.
How much does it cost to get a determination of heirship in Texas?
Typically $2,000–$5,000 in attorney fees plus court costs, taking two to four months. The figure varies by county, number of heirs, and whether any heirs are disputed or unlocated. Get a quote from a local probate attorney for your situation.
How long does a Texas affidavit of heirship take to be effective?
The affidavit can be prepared and recorded within a few weeks. Under Texas Estates Code § 203.001, it creates a rebuttable presumption of title only after five years on record. Some underwriters will insure sooner, but five years is the standard threshold.
