Per Stirpes

The 30-Second Summary

What is Per Stirpes? A Plain English Definition

Imagine you've spent a lifetime carefully planting and tending to an orchard. Your plan is to leave one major section of the orchard to each of your three children. But what if, tragically, one of your children passes away before you do, leaving behind children of their own (your grandchildren)? Who gets that section of the orchard now? This is precisely the question that “Per Stirpes” answers for your financial assets. In the simplest terms, Per Stirpes is an instruction that says, “If one of my direct heirs is no longer living when I pass away, their intended share should go directly to their children.” The term is Latin for “by the roots” or “by the branch,” which is the perfect analogy. You are instructing your estate to be divided by the main branches of your family tree. Each child represents a primary branch, and their share will flow down that branch, even if they are no longer there to receive it themselves. The most common alternative is called “Per Capita,” which means “by the head.” In a Per Capita distribution, your assets are divided equally among only the surviving named beneficiaries. If one of your children has passed away, their share is simply re-absorbed and split among the surviving children. Their own kids—your grandchildren—would get nothing. Think of it this way:

For a value investor who thinks in terms of decades and generations, understanding this distinction isn't just a legal formality; it's the final and most critical step in stewarding the wealth you've so patiently built.

“Someone's sitting in the shade today because someone planted a tree a long time ago.” - Warren Buffett
A wise estate plan, using tools like Per Stirpes, ensures that the shade from the tree you planted will cover not just your children, but your grandchildren and beyond.

Why It Matters to a Value Investor

At first glance, a legal inheritance term might seem out of place in an investment dictionary. But for a true value investor, it's one of the most important concepts of all. Value investing isn't just about picking good stocks; it's a philosophy of building and preserving wealth over the very long term. Your estate plan is the mechanism that determines whether that wealth survives you. Here’s why Per Stirpes is a critical concept for a value investor:

Choosing Per Stirpes is an act of foresight, discipline, and stewardship—the very same character traits that define a successful value investor.

How to Apply It in Practice

This isn't a financial ratio to calculate, but a crucial method to apply across your financial life. Implementing it is surprisingly simple, but requires diligence.

The Method

  1. Step 1: Audit Your Accounts. Make a list of every single account that has a beneficiary designation. This includes:
    • Retirement Accounts: Traditional & Roth IRAs, 401(k)s, 403(b)s.
    • Brokerage Accounts: Specifically those with a Transfer on Death (TOD) registration.
    • Life Insurance Policies.
    • Annuities.
    • Bank Accounts: With a Payable on Death (POD) designation.
  2. Step 2: Locate the Beneficiary Form. For each account, you will need to review the current beneficiary designation form. You can usually find this online in your account portal or by calling the financial institution.
  3. Step 3: Make the Designation. On the form, you don't just write your child's name. You add the key phrase. For example, if you have two children, Jane Doe and John Doe, you would write:
    • Primary Beneficiary 1: Jane Doe, Per Stirpes
    • Primary Beneficiary 2: John Doe, Per Stirpes
    • Many modern forms now have a simple checkbox for Per Stirpes or Per Capita next to each beneficiary's name, making it even easier.
  4. Step 4: Acknowledge the “Superpower” of Beneficiary Forms. This is a critical point that many investors miss: Beneficiary designations on these accounts override your will. You could have a beautifully written will that details your wishes, but if your 20-year-old 401(k) form says something different, the 401(k) form wins. Ensure your will and your beneficiary designations are all telling the same story.

Interpreting the Choice: Per Stirpes vs. Per Capita

The best way to understand the impact of your choice is with a direct comparison.

Scenario Per Stirpes Distribution Per Capita Distribution (The Default)
You have a $3M portfolio and name your 3 children (Alice, Bob, Carol) as beneficiaries. Bob tragically passes away before you. Bob has two children of his own. Your estate is first divided into three equal “branches” ($1M each). Your estate is divided equally only among the surviving named beneficiaries.
Result: Alice gets her $1M share. Carol gets her $1M share. Bob's $1M share flows down his “branch” to his two children, who each receive $500,000. Result:
Alice and Carol are the only two survivors. They each receive $1.5M. Bob's two children receive $0.00.
Investor's Intent: Aligns with the goal of providing for all branches of the family equally. Often leads to the unintentional and heartbreaking disinheritance of grandchildren.

This table clearly illustrates that failing to specify Per Stirpes can have dramatic and often undesirable consequences.

A Practical Example

Let's consider Eleanor, a disciplined value investor who is now 80 years old. Over 50 years, by diligently investing in wonderful companies at fair prices and letting them compound, she has built a $2 million IRA. Eleanor has two children: Mark and Susan.

Years ago, Eleanor filled out her IRA beneficiary form, simply naming “Mark” and “Susan” as 50/50 beneficiaries. Scenario A: The “Per Capita” Default Last year, Mark sadly passed away from an illness. This year, Eleanor passes away. Because her beneficiary form did not specify “Per Stirpes,” the financial institution follows the default “Per Capita” rules.

This was not Eleanor's wish. She loved Peter dearly and would have been horrified to know her life's savings bypassed him completely. Scenario B: The “Per Stirpes” Solution Now, let's imagine Eleanor, being the prudent planner she is, had read about Per Stirpes. Years ago, she updated her beneficiary form to read:

When Eleanor passes away, the distribution plays out very differently:

By adding two simple words, Eleanor ensured her intentions were honored, her legacy was protected, and all branches of her family were treated as she wished.
