When a person dies and leaves real estate as part of their estate, two different documents might be used to authorize the person managing the estate to sell that property: a Grant of Probate or Letters of Administration.

Both documents serve the same ultimate function – they are the legal credential that enables an executor or administrator to act on behalf of the estate – but they arise in different circumstances and involve meaningfully different processes.

Understanding the distinction between these documents matters practically for anyone involved in selling estate property, because it affects who has authority, how quickly that authority can be obtained, and what procedural requirements apply to the sale.

What Is a Grant of Probate?

A Grant of Probate (often called Letters Testamentary in the United States) is issued by the probate court when a deceased person left a valid will. The grant accomplishes two things simultaneously: it confirms that the will is valid and legally operative, and it appoints the executor named in the will to administer the estate.

The term ‘Grant of Probate’ is more commonly used in English and Commonwealth legal systems, while U.S. courts typically use ‘Letters Testamentary.’ However, the underlying concept is the same, and the terms are often used interchangeably in discussions of U.S. probate law. Both refer to the formal court authorization given to an executor under a validated will.

The executor named in the will – once Letters Testamentary are issued – has the legal authority to manage estate assets, pay debts, and ultimately sell real property in accordance with the estate’s needs and the will’s directives.

What Are Letters of Administration?

Letters of Administration serve the same practical function as Letters Testamentary, but they are issued in situations where there is no valid will. This typically means:

• The deceased person died intestate (without a will)
• A will exists but has been rejected as invalid by the court
• The named executor has died, declined to serve, or been disqualified, and no alternate was named
• A will exists but does not effectively address all of the deceased’s property, leaving some assets subject to intestate distribution

When any of these situations applies, the probate court appoints an administrator – typically following a statutory priority order that favors the surviving spouse, then adult children, then other relatives – and issues Letters of Administration granting that person authority to administer the estate.

The administrator’s authority under Letters of Administration is functionally equivalent to an executor’s authority under Letters Testamentary. Both can sign deeds, enter into purchase agreements, and convey estate property to buyers. The difference lies not in what these documents authorize but in how they are obtained and under what circumstances. See also: do you need letters of administration to sell an inherited property.

Key Differences Between the Two Documents

Origin and Triggering Circumstances

Letters Testamentary arise from a will – they validate the testator’s choice of executor and the testator’s instructions for the estate. Letters of Administration arise from the absence of a valid will (or the absence of a functioning executor), and the administrator is appointed by the court according to law rather than by the deceased’s personal choice.

Identity of the Authorized Person

Under Letters Testamentary, the authorized person is who the deceased nominated. Under Letters of Administration, the authorized person is determined by the court’s application of the statutory priority rules. This can matter significantly when family relationships are complex or when potential administrators have competing interests.

Court Oversight

The degree of ongoing court oversight can differ between the two types of administration, though this depends primarily on state law rather than the document type itself. In many states, both executors and administrators can apply for independent administration authority, which allows them to proceed with property sales and other significant transactions without returning to court for approval of each action.

Process for Obtaining Each Document

Obtaining Letters Testamentary requires filing the will with the court and petitioning for its admission to probate. If the will is uncontested and properly executed, the process is relatively straightforward.

Obtaining Letters of Administration when there is no will requires the court to determine who is entitled to appointment as administrator. If multiple potential administrators are competing for the role – for example, if two siblings both seek appointment – the court may need to hold additional hearings to resolve the dispute, which adds time to the process.

Property Sale Authority: Practical Implications

For the purpose of selling estate real property, the practical authority granted by Letters Testamentary and Letters of Administration is equivalent. Both authorize the holder to:

• Engage a real estate agent and list the property
• Accept and negotiate offers
• Sign a purchase and sale agreement
• Authorize inspections and appraisals
• Execute a deed transferring title to the buyer
• Receive sale proceeds into the estate

However, in both cases, the executor or administrator must comply with any additional requirements imposed by state law. In supervised administration states, court confirmation of the sale may be required regardless of whether the authority came from Letters Testamentary or Letters of Administration. In independent administration states, the holder of either type of letters can generally proceed without court involvement in each specific transaction.

When Each Document Is Issued and How Long It Takes

Letters Testamentary Timeline

The petition for Letters Testamentary is typically filed within the first weeks after the death. The court reviews the petition and the will, schedules a hearing (if required), and issues the Letters once the will has been admitted to probate and the executor formally appointed. In uncontested cases, this can happen within two to six weeks of filing, though some courts with heavy dockets take longer.

Letters of Administration Timeline

Letters of Administration often take somewhat longer to obtain, for a few reasons. There is no will to guide the process, so the court must determine heirship and the appropriate administrator. If potential administrators disagree about who should be appointed, additional hearings are necessary. In straightforward situations – a surviving spouse with no competing applicants, for instance – the timeline can be similar to obtaining Letters Testamentary. In contested situations, it can take several months. See also: how long does it take to get probate approval to sell property.

Administrator With Will Annexed

One variant worth noting is the Administrator With Will Annexed, known as an Administrator CTA (from the Latin cum testamento annexo). This type of appointment arises when a will exists and has been admitted to probate, but the executor named in the will cannot serve. In this case, the court appoints an administrator to carry out the will’s provisions, issuing a document that combines elements of both types of letters.

For property sales, this administrator has the same authority as a regular executor – they are bound by the will’s terms and the court’s oversight requirements. Their authority derives from the court’s appointment, not from the will directly, but the effect on their ability to sell property is the same.

Executor vs Administrator: Roles and Responsibilities

Beyond the formal document differences, the roles of executor and administrator carry the same core responsibilities:

• Both owe fiduciary duties to the estate’s beneficiaries
• Both must act in the estate’s best interests, not their own
• Both must account to the court for their administration of the estate
• Both must pay estate debts and taxes before distributing assets
• Both are subject to removal by the court if they breach their duties

The primary practical difference is that an executor acts according to the testator’s expressed wishes (as set out in the will), while an administrator distributes the estate according to the state’s intestacy laws, regardless of what the deceased might have preferred. For property sales, both must achieve fair market value and comply with applicable probate court requirements.

What Buyers and Title Companies Need to Know

From a buyer’s perspective, whether a property sale is authorized by Letters Testamentary or Letters of Administration makes little practical difference. Both documents provide the same foundation for a valid title transfer. What matters is:

• That the letters are current – most title companies require letters issued within 60 to 90 days
• That the person named in the letters is the person signing the deed
• That any required court confirmation of the sale has been obtained
• That all notice and procedural requirements under state law have been followed

Title companies are experienced in reviewing probate documentation and will specify exactly what they need. Working with a probate-experienced title officer and attorney significantly reduces the risk of procedural errors that could delay or derail the closing.

Conclusion

A Grant of Probate (Letters Testamentary) and Letters of Administration both authorize the person managing an estate to sell real property, but they arise in different circumstances. Letters Testamentary are issued when a valid will exists and the named executor is appointed; Letters of Administration are issued when there is no valid will or when the executor cannot serve.

For practical purposes – including listing the property, accepting offers, and closing the sale – both documents confer equivalent authority, subject to the state’s requirements for court oversight. The key variable is not which document applies but whether additional court approval of the sale is required in the relevant state, and how efficiently the authorized person manages the process from listing to closing.
