National Dictionary Day: 5 Probate Words Every Future Executor Needs to Know

National Dictionary Day: 5 Probate Words Every Future Executor Needs to Know

Today is National Dictionary Day! Let's celebrate Noah Webster—the man who published the first American English dictionary in 1828 - in today's post. Webster believed that clear language was essential for a functioning society.  As an estate planning and probate attorney, I concur. Probate and estate planning are notorious for using antique legal jargon that leaves grieving family members scratching their heads. When you are named as an executor (or Personal Representative), opening court documents can feel like reading a foreign language.

Here is a practical dictionary guide to 5 tricky legal words every future executor—and estate planner—needs to know.

1. Intestate /in-ˈtes-ˌtāt/ (adjective)
The Legalese: Dying without a valid Last Will and Testament.

Plain English: Leaving no roadmap behind. When someone dies "intestate," they don't lose their estate to the state, but state statutes step in to decide who inherits their assets and who manages the process.

Why It Matters: Probate administration for an intestate estate is often slower and more expensive because the court must follow rigid legal formulas rather than the deceased person's actual wishes.

2. Issue /ˈi-shü/ (noun)
The Legalese: All direct linear descendants of a person (children, grandchildren, great-grandchildren).

Plain English: Your biological or legally adopted offspring down the family tree. In standard conversational English, "issue" means a problem or a magazine edition. In probate law, "having issue" simply means having direct descendants.

Why It Matters: Wills often leave assets "to my surviving issue, per stirpes." If a document uses this term, it has specific legal consequences for how shares flow down to grandchildren if a child passes away first.

3. Appraisal vs. Assessment /ə-ˈprā-zəl/ vs. /ə-ˈse-smənt/ (nouns)
The Legalese:

Appraisal: An independent, professional opinion of fair market value at a specific point in time.

Assessment: A local government’s tax valuation used strictly for property tax calculations.

Plain English: The tax man's number vs. the real-world buyer's number.

Why It Matters: Executors frequently make the mistake of using the municipal property tax assessment on a inventory form. In probate, courts and tax authorities usually require a real appraisal showing the true fair market value on the exact date of death to properly calculate court fees, step-up in cost basis, and estate taxes.

4. Domiciliary Letters /ˌdä-mə-ˈsi-lē-ˌer-ē ˈle-tərz/ (noun)
The Legalese: The official court document issued by the probate registrar or judge granting a Personal Representative legal authority to act on behalf of an estate.

Plain English: The ultimate golden ticket.

Why It Matters: Clients often ask me, "Where is the 'letter' my father wrote?" Domiciliary Letters aren't correspondence—they are formal court certificates. Banks, title companies, and investment firms will not allow an executor to touch accounts or sell a house until they see an official, certified copy of these letters.

5. Fiduciary /fə-ˈdü-shē-ˌer-ē/ (noun or adjective)
The Legalese: A person or entity holding a legal relationship of high trust and ethical duty to act solely in the best interests of another.

Plain English: Being legally bound to put someone else’s financial interest above your own.

Why It Matters: An executor is a fiduciary. This means they cannot self-deal, commingle estate funds with their personal bank accounts, or favor one beneficiary over another. Holding a fiduciary role carries real legal liability, which is why transparency and meticulous record-keeping are essential from day one.


You do not need a law degree to navigate estate administration, but having a clear dictionary helps. Whether you are drafting your own estate plan or stepping up to help settle a loved one's estate, demystifying these key terms is the first step toward a smooth, stress-free process.
