Can an Estate Reinvest Funds During Administration? (w/Examples) + FAQs

Yes, an executor can reinvest estate funds, but this power is strictly controlled and is not a license to gamble with a beneficiary’s inheritance. The primary problem an executor faces is a direct conflict between two legal duties: the duty to protect the estate’s assets and the duty to make those assets productive. This conflict is governed by a legal standard known as the Uniform Prudent Investor Act (UPIA), which requires a sophisticated, portfolio-based investment strategy that is often beyond the skills of a non-professional executor. A single misstep under this rule can make an executor personally liable to repay any investment losses from their own pocket.

With the average estate administration lasting 12 to 18 months, there is very little time for a portfolio to recover from market downturns, making risky investments especially dangerous. This guide breaks down the rules in simple terms so you can perform your duties correctly and protect yourself from liability.

The Key Players: Who’s Who in Estate Administration

An estate is managed by several key people and entities. The Executor is the person named in the will to manage the estate. If there is no will, the court appoints someone called an Administrator to do the same job. Both are considered the “personal representative” of the estate.

The Beneficiaries (or Heirs) are the people or organizations who will inherit the assets from the estate. The executor works for them. The entire process is overseen by the Probate Court, which is a state court that handles wills, estates, and trusts.

The executor has a special legal responsibility called a fiduciary duty. This is the highest standard of care under the law. It means the executor must always act in the best interests of the beneficiaries, with complete loyalty and honesty.

The Executor’s Core Conflict: Guarding the Money vs. Growing the Money

An executor’s job involves two main duties that often seem to contradict each other. The first and most important duty is to preserve and protect the estate’s assets. This means the executor must find all the assets, secure them, and prevent them from being lost, damaged, or stolen.

Practical steps include opening a dedicated, interest-bearing bank account for the estate, insuring property like homes and cars, and taking control of financial accounts. An executor must never mix their personal money with the estate’s money, an illegal act known as commingling.

The second duty is to make the estate’s assets productive. An executor cannot let a large amount of cash sit in a non-interest-bearing checking account for a year while probate is ongoing. This duty is the legal basis for investing estate funds.

This creates the central conflict: how do you grow money without risking it? The answer is that an executor’s primary goal is capital preservation, not growth. Your job is to prevent the estate’s value from shrinking, not to act like a day-trader trying to make a profit. The short timeline of estate administration makes aggressive, long-term investment strategies unsuitable and dangerous.

The Modern Rulebook: Understanding the Prudent Investor Rule

For over a century, executors followed the “Prudent Man Rule,” which judged each investment on its own. This old rule encouraged being overly cautious, as a single “risky” stock could lead to liability, even if it was part of a balanced plan. Today, nearly every state has replaced it with the Uniform Prudent Investor Act (UPIA), a modern and more flexible standard.

The UPIA is based on a few simple but powerful ideas from modern portfolio theory.

First, it uses a total portfolio approach. This means an investment is judged not in isolation, but on how it fits into the estate’s overall investment strategy. A single investment might seem risky, but it could be considered prudent if it helps diversify the entire portfolio.

Second, the executor has a duty to diversify the estate’s investments. Holding a large portion of the estate in a single stock or property is extremely risky and often a breach of this duty. The will can sometimes override this rule, but without specific instructions, diversification is mandatory.

Most importantly, the Prudent Investor Rule is a test of conduct, not performance. You are judged on the quality of your decision-making process, not the final outcome. A well-researched, conservative investment that loses money in a surprise market crash may not lead to liability. However, a reckless gamble that happens to make money could still be considered a breach of your duty.

The Power Hierarchy: Who Gives You Permission to Invest?

An executor’s authority to invest comes from three sources, which are ranked in order of importance.

1. The Will or Trust Document

The will is the most powerful source of authority. A well-drafted will can give an executor broad powers to invest in a wide range of assets. It can also restrict an executor, for example, by ordering them to hold a specific family business or piece of real estate. The executor must follow the will’s instructions.

2. State Law

If the will is silent about investing, the executor’s powers are determined by state law. These laws act as the default rules. While most states follow the Prudent Investor Rule, the specific details can vary.

| State | Default Investment Power | Key Restriction | |—|—| | California | An executor can invest surplus funds as they deem “advisable.” | The law explicitly prohibits “speculative investments.” Caution is the primary focus. | | New York | The law explicitly grants fiduciaries the power “to invest and reinvest property of the estate.” | Investments are governed by New York’s Prudent Investor Act, which requires diversification and a suitable strategy. | | Florida | Governed by the Prudent Investor Rule, allowing investment in any property type as long as the process is prudent. | There is an explicit statutory duty to diversify unless special circumstances make it unwise. | | Texas | The Prudent Investor Rule is the default standard, which can be altered by the will. | Decisions must be evaluated in the context of the total portfolio, with a focus on reasonable care, skill, and caution. |

3. The Probate Court

The final layer of authority is the court itself. Even if an executor has the power to act independently, they can always petition the court for approval of a significant or unusual investment. Getting a court order provides a powerful shield against future lawsuits from beneficiaries, as it proves the action was approved by a judge.

Your Game Plan: Crafting a Safe Investment Strategy for an Estate

An executor’s investment plan must be tailored to the unique, short-term nature of an estate. It is fundamentally different from planning for retirement or other long-term goals.

The Short-Term Mindset: An Estate is a Temporary Holding Pen

The probate process typically lasts between 12 and 18 months. This short window means there is no time to recover from market losses. Therefore, any investment strategy must prioritize protecting the principal value of the assets over chasing high returns.

Cash is King: The Critical Need for Liquidity

An estate has bills that need to be paid now. These include funeral costs, attorney’s fees, court fees, debts of the person who died, and taxes. Liquidity refers to having enough cash or easily sold assets to cover these expenses.

Without enough liquidity, an executor might be forced into a “fire sale,” selling valuable assets like real estate or a business at a deep discount just to raise cash quickly. This harms the beneficiaries and can expose the executor to personal liability. A prudent executor always maintains a healthy cash reserve.

Choosing Your Path: Conservative is the Only Safe Road

Because of the short time horizon and the need for liquidity, a conservative investment strategy is the only appropriate choice for most estates.

A conservative strategy focuses on capital preservation. The goal is to avoid losing money. Suitable investments are low-risk and can be sold quickly, such as:

High-yield savings accounts
Money market funds
Short-term government bonds
Certificates of Deposit (CDs)

An aggressive strategy, which focuses on growth, is almost always inappropriate and imprudent for an executor. Taking risks with estate funds is a direct violation of the duty to preserve assets. The only potential exception is if the estate assets are designated to fund a long-term trust, but this requires expert legal and financial advice.

The Tax Secret Every Executor Must Know: The “Step-Up in Basis”

One of the most powerful tools available to an executor is a tax rule called the step-up in cost basis. Understanding this rule is critical for managing inherited stocks, real estate, and other assets that have grown in value.

The “cost basis” is the original price paid for an asset. When you sell an asset for more than its basis, the profit is a “capital gain,” and you owe taxes on it.

However, when a person dies, the cost basis of their assets is “stepped up” to the fair market value on the date of their death. This means the old cost basis is erased and replaced with a new, higher one.

The consequence of this is enormous: if an executor sells an inherited stock or property shortly after the owner’s death, there is often little or no capital gain to tax. This tax break removes the main financial reason for holding onto appreciated assets. It perfectly aligns the executor’s duty to reduce risk (by selling volatile stocks) with the most tax-efficient path (selling creates no tax bill).

Real-World Scenarios: Learning from Executor Mistakes

Theory is one thing, but seeing how these rules play out in real life is the best way to learn. Here are three common scenarios that executors face.

Scenario 1: The Volatile Tech Stock

An estate’s main asset is $500,000 worth of a single, volatile tech stock. One beneficiary begs the executor to hold it, believing it will go up. The executor hesitates to sell, and three months later, the stock crashes, losing $200,000 in value.

Executor’s Choice	Painful Outcome
Held a concentrated, risky stock position, violating the duty to diversify.	The executor is personally liable for the $200,000 loss. A prudent executor would have sold the stock immediately, taking advantage of the step-up in basis to avoid taxes and risk.
Listened to a beneficiary’s speculative advice instead of following fiduciary duties.	The other beneficiaries can sue the executor for the loss. Beneficiary wishes do not override the executor’s legal duties.

Scenario 2: The Family Business

An executor inherits a small, operating business. The will is silent on what to do with it. The executor decides to keep running the business for a year to try to increase its sale price, but a key employee quits and sales decline.

Management Decision	Financial Result
Continued to operate a complex asset without expertise, exposing the estate to business risk.	The business loses value, and the executor may be liable. The prudent action is to get a professional valuation and sell or wind down the business promptly.
Failed to act decisively to preserve the asset’s value at the time of death.	Beneficiaries are harmed by the decline in value. An executor’s job is to liquidate and distribute, not to become a long-term business manager.

Scenario 3: The Real Estate “Flip”

An estate includes a house that needs repairs. The executor decides to use $50,000 of the estate’s cash to renovate the kitchen and bathrooms, believing it will increase the sale price by $100,000.

Investment Action	Legal Consequence
Used liquid estate funds for a speculative real estate investment.	This is generally considered an improper use of estate funds. Such a major, non-essential expense requires beneficiary consent or a court order.
Tied up cash needed for taxes and other expenses in an illiquid asset.	If the estate runs short on cash, the executor may be personally liable for failing to plan for liquidity needs. The renovation may not return the expected value.

Mistakes to Avoid: The Executor’s Minefield

Serving as an executor is filled with potential traps. Here are some of the most common and costly mistakes to avoid.

Acting Like a Day-Trader: Your job is to protect, not to play the market. Using estate funds for speculative investments is a direct breach of your duty.
Failure to Liquidate Risky Assets: Holding onto a concentrated stock position or other volatile assets is one of the easiest ways to get sued. The prudent move is almost always to sell and move the funds into a safe, interest-bearing account.
Self-Dealing: You cannot use your position for personal benefit. This includes investing estate funds in your own business, buying estate assets for yourself at a discount, or hiring your own company to perform services for the estate.
Ignoring the Need for Liquidity: Always make sure you have enough cash on hand to pay all the estate’s bills. Do not invest money that might be needed for taxes or debts in the near future.
Poor Record-Keeping: Document every single financial decision. A written investment plan and detailed records of all transactions are your best defense if your actions are ever questioned.

Do’s and Don’ts for Investing Estate Funds

Do’s	Don’ts
✅ Do open a separate, insured, interest-bearing bank account for the estate immediately.	❌ Don’t mix any estate funds with your own personal money for any reason.
✅ Do create a simple, written Investment Policy Statement outlining a conservative strategy.	❌ Don’t make any investments without a clear, documented plan that justifies your decisions.
✅ Do consult with professionals, like an estate attorney and a financial advisor.	❌ Don’t rely on your own investing experience, as the rules for fiduciaries are different.
✅ Do prioritize liquidity and capital preservation above all other goals.	❌ Don’t invest in anything speculative, volatile, or illiquid, like private businesses or new real estate.
✅ Do take advantage of the “step-up in basis” to sell appreciated assets with minimal tax.	❌ Don’t hold onto a concentrated or risky stock portfolio out of fear of taxes or hope for a rebound.

Pros and Cons of Reinvesting Estate Funds

Pros of Reinvesting	Cons of Reinvesting
Fulfills the legal duty to make estate assets productive and not let them sit idle.	Creates a significant risk of personal liability for the executor if investments lose money.
A modest, safe return can help offset inflation and the ongoing costs of administration.	The short 12-18 month time horizon is unsuitable for most types of growth investments.
Can generate a small, steady income stream to help pay for estate expenses.	Can lead to disputes with beneficiaries who may disagree with the investment choices.
Demonstrates active and diligent management of the estate’s assets.	Requires a level of financial expertise that many non-professional executors do not possess.
May be required by the terms of the will or state law.	The primary goal is preservation, and even “safe” investments carry some level of risk.

The Process: How to Handle an Inherited Brokerage Account

When you take over an estate that includes a brokerage account, you must follow a specific process to gain control and manage the assets.

Notify the Brokerage Firm: The first step is to inform the financial institution of the account holder’s death.
Gather Required Documents: The firm will require legal paperwork to prove you have authority to act. This always includes an original death certificate and a court document called Letters Testamentary, which is the official order appointing you as executor.
Open a New Estate Account: The assets cannot stay in the deceased person’s name. You will need to open a new brokerage account titled in the name of the estate (e.g., “Estate of Jane Doe, John Smith, Executor”).
Transfer the Assets: The firm will move the stocks, bonds, and other securities from the old account into the new estate account.
Implement Your Investment Plan: Once you have control, you must act. This is the point where you, ideally with a financial advisor, sell the risky assets and reinvest the proceeds according to your conservative investment policy.

Your Support Team: You Don’t Have to Do It Alone

Being an executor does not mean you have to be an expert in law, finance, and taxes. In fact, the Prudent Investor Rule encourages seeking professional help. The costs for these experts are paid by the estate, not by you personally.

Estate Attorney: This is your most important partner. They provide legal guidance, help you interpret the will, handle court filings, and ensure you are following all state laws.
Financial Advisor: A financial advisor helps you create the written investment policy, analyze the existing portfolio, and execute the trades needed to align the estate’s assets with your conservative strategy.
Accountant (CPA): A CPA is crucial for handling all tax matters, including the decedent’s final income tax return and any estate or inheritance tax returns that may be required.

When Beneficiaries Disagree With Your Decisions

Disputes with beneficiaries are a common source of stress for executors. One beneficiary might want you to hold a risky stock, while another wants you to sell everything and hold cash.

In these situations, your duty is to remain neutral and act in the best interest of the entire estate, not just one beneficiary. The landmark court case Karo v. Wachovia Bank, N.A. provides a key lesson: getting written, informed consent from all beneficiaries before making a controversial decision is a powerful defense. If the beneficiaries agree to a specific investment plan, have them sign a document confirming their consent.

If beneficiaries cannot agree, do not take sides. Your safest options are to stick to an ultra-conservative plan or, as a last resort, petition the court for instructions. This lets a judge make the final call, which protects you from liability.

Frequently Asked Questions (FAQs)

Can I just leave the money in the deceased’s bank account? No. You must open a new, separate, interest-bearing estate account. This prevents illegal commingling of funds and fulfills your duty to properly manage and make assets productive for the estate.

Am I personally liable if an investment I make loses money? Yes, you can be. If you acted imprudently, took speculative risks, or failed to follow a proper process, you may have to repay the loss from your own pocket.

Do I have to sell all the inherited stocks? No, but you must have a prudent, documented reason for holding them. Failing to sell a risky or highly concentrated stock position is a common and dangerous mistake that can lead to personal liability.

Can I use estate funds to invest in a new piece of real estate? No. This is almost always considered too speculative and illiquid for an estate. It would likely require specific permission in the will or a court order, both of which are extremely rare.

What if a beneficiary pressures me to make a risky investment? No. Your legal duty is to the will and the law, not to a single beneficiary’s demands. You must resist pressure to speculate and should document their request and your prudent refusal in writing.
