A testate estate is the property and debts left behind by a person who died with a valid will. Because that will exists, the deceased person’s written instructions decide who inherits, who manages the estate, and which specific items go to which people. Without a valid will, those decisions fall to a rigid formula in state law.
Testate and Intestate: The Core Difference
“Testate” means “with a will.” The person who wrote it is the testator. When someone dies testate, the will guides distribution. When someone dies intestate, the state’s intestacy laws take over and assign assets along a fixed hierarchy, usually starting with a surviving spouse and children and moving outward to parents, siblings, and more distant relatives.1Legal Information Institute. Intestate Succession
That hierarchy ignores anyone outside it. A close friend, a charity, a stepchild raised from infancy — none of them inherit under intestacy unless state law happens to place them in line. If no heirs can be found at all, the property goes to the state under a process called escheat. A valid will prevents that result and lets the testator name whoever they want.
Partial intestacy is also possible. If the will exists but fails to address every asset the testator owned, the covered assets pass under the will and the leftover assets pass under intestacy law. The estate ends up testate and intestate at the same time, which rarely matches what the testator had in mind.
What Makes the Will Valid
A testate estate depends on a will that will actually hold up in probate court. Rules vary by state, but the core requirements are consistent:
- The will must be in writing. Oral wills are recognized only in extremely narrow circumstances in a few states.
- The testator must sign it, or direct someone to sign on their behalf in their presence.
- Most states require at least two witnesses who watch the signing and then sign themselves. Witnesses should not be beneficiaries.2Justia. Wills Legal Forms: 50-State Survey
- The testator must generally be at least 18.
- The testator must have testamentary capacity — understanding what they own, who their natural beneficiaries are, and what signing the will does — and must sign free of pressure or manipulation.
A holographic will, written entirely in the testator’s own handwriting and signed but not witnessed, is accepted in some states and rejected in others.3Legal Information Institute. Holographic Will A few states only recognize them in limited circumstances, such as for armed forces members on active service. Relying on one in a state that rejects them can leave the estate intestate.
A self-proving will adds a sworn affidavit signed by the witnesses, usually before a notary, at the time the will is executed. The affidavit does not change the will’s content. It just removes the need for witnesses to appear in court later to confirm the signing, which can be a real problem if witnesses have moved, become incapacitated, or died.4Legal Information Institute.

Which Assets Actually Pass Under the Will
A will does not control everything the deceased owned. The testate estate consists of assets owned solely by the deceased with no built-in transfer mechanism. Typical examples: real estate titled only in the deceased person’s name, bank accounts without a payable-on-death designation, vehicles, furniture, jewelry, and collectibles.
Several categories of property bypass the will entirely and go straight to a named beneficiary or surviving co-owner:
- Jointly owned property with rights of survivorship shifts automatically to the surviving co-owner.
- Retirement accounts such as IRAs and 401(k)s pass to whoever is listed on the beneficiary form.
- Life insurance proceeds go to the named beneficiary.
- Payable-on-death and transfer-on-death bank and brokerage accounts transfer directly to the named person.
- Assets held in a living trust are distributed by the trustee under the trust terms.
This matters more than people realize. If a retirement account’s beneficiary form names an ex-spouse, the ex-spouse inherits that account no matter what the will says. Beneficiary designations and joint-ownership arrangements beat the will every time. Keeping those forms current is as important as keeping the will current.
How a Testate Estate Is Settled
After the testator dies, the will goes through probate — a court-supervised process that confirms the will’s validity and oversees settlement of the estate. The person named as executor files the will with the local probate court along with a petition to open the estate.
If the court accepts the will and approves the executor, it issues letters testamentary. This court document is the executor’s proof of authority. Without it, banks, title companies, and other institutions will not let the executor access accounts, sell property, or conduct estate business.5Legal Information Institute. Letters Testamentary The will alone does not grant the executor power to act; the court order does.
From there the executor inventories and values the assets, notifies known creditors and publishes notice for unknown ones, pays valid debts and taxes from estate funds, files a detailed accounting with the court, and distributes what remains to the beneficiaries named in the will. Beneficiaries can review the accounting and object if something looks wrong.
Timelines vary widely. A straightforward estate with few assets and no disputes can wrap up in under a year. A contested estate or one with complicated holdings can stretch on for several years.
If the person named as executor has died, become incapacitated, or does not want the job, the alternate executor named in the will steps in. If no alternate is named, the court appoints someone to serve as personal representative, often a surviving spouse or adult child. Naming a backup in the will avoids that uncertainty.
Challenges to the Will
A valid will is not immune to challenge. Beneficiaries, disinherited family members, or people who stood to inherit under a prior will can file a will contest during probate. The challenger carries the burden of proof. Common grounds include:
- Lack of testamentary capacity, often raised when dementia or other cognitive decline was present at signing.
- Undue influence, where someone close to the testator pressured or manipulated them into writing or changing the will.
- Fraud, such as the testator being deceived about what document they were signing.
- Improper execution, meaning the will fails a formal requirement like the right number of witnesses or a valid signature.
- Revocation, where evidence shows the testator destroyed the will, wrote a new one, or otherwise revoked it under state law.
Some wills include a no-contest clause (also called an in terrorem clause) that disinherits any beneficiary who challenges the will and loses. Enforceability varies. Some states enforce them strictly; others refuse to penalize a challenger who had reasonable grounds, even if the challenge failed. The clause has no effect on someone who was already disinherited, since that person has nothing to lose.
Taxes the Executor Handles
The executor settles all tax obligations before distributing anything to beneficiaries.
The federal estate tax applies only to estates above the exemption threshold. For 2026, the individual exemption is $15,000,000 under legislation signed in July 2025.6Internal Revenue Service. What’s New – Estate and Gift Tax Married couples can effectively double that through portability, where the surviving spouse claims the unused portion of the deceased spouse’s exemption. Estates above the threshold face a top federal rate of 40% on the excess. Most estates owe no federal estate tax, but the executor still has to determine whether a return is required.
State taxes are separate. A handful of states impose their own estate tax, sometimes with much lower exemptions than the federal one. A few states levy an inheritance tax, paid by the individual beneficiary rather than the estate. One state imposes both. The executor should check the laws of every state where the deceased owned property, not just the state of residence.
The executor also files the deceased person’s final individual income tax return for the period from January 1 through the date of death. If the estate itself earns income during administration — from interest, rent, or investments — a separate income tax return for the estate is required as well.
