Right of representation and per stirpes are closely related inheritance distribution methods, and in many families they produce the exact same result, but they are not always identical. The difference shows up when every heir in the children’s generation has died before the person who left the estate. Strict per stirpes still divides the estate at the children’s level and sends each branch’s share down to that branch’s descendants. Right of representation moves the starting point of the division down to the first generation that still has living members, so grandchildren in that situation share equally rather than inheriting by branch.
How Per Stirpes Divides an Estate
Per stirpes is Latin for “by the branch.” The estate is divided at the level of the deceased person’s children, and each child’s branch gets an equal share. That split happens whether or not any of the children are still alive. If a child has died but left descendants, that child’s share flows down to those descendants instead of being redistributed among surviving siblings.
Picture permanent lanes carved at the first generation. A parent with three children creates three lanes, each carrying one-third of the estate. A living child takes their third outright. A deceased child’s third drops down to their own children, who split it equally among themselves. The branch controls the math, not the number of living people inside it.
This approach is sometimes called “strict per stirpes” or the English method. It can produce noticeably unequal results among grandchildren. If one deceased child left a single heir and another deceased child left four, the solo grandchild receives a full one-third while each of the four cousins receives only one-twelfth.
How Right of Representation Divides an Estate
Right of representation, also called “modern per stirpes” or “modified per stirpes,” shifts where the division begins. Instead of always starting at the children’s level, this method looks for the first generation that still has at least one living person and starts the split there.
When at least one child is still alive, right of representation and strict per stirpes produce the identical result. The estate divides at the children’s level, living children take their shares, and the shares of deceased children drop down to their own descendants.
The two methods diverge only when the entire children’s generation is gone. Strict per stirpes still divides at that empty level, locking in the branch structure. Right of representation skips the empty generation and divides at the grandchildren’s level, treating each surviving grandchild as a primary beneficiary and giving each an equal slice. The branching structure stops controlling the math.
A Worked Example
Consider a $900,000 estate left by Alex, who had three children: Blake, Casey, and Drew. Casey died leaving one child (Evan). Drew died leaving three children (Faye, Grace, and Henry). Blake is still alive.
Because Blake survives, both methods produce the same outcome:
- Blake receives $300,000 (one-third).
- Evan receives $300,000, inheriting Casey’s full one-third.
- Faye, Grace, and Henry each receive $100,000, splitting Drew’s one-third three ways.
Evan ends up with three times what each of Drew’s children receives, even though they are all grandchildren. That is branch logic at work.
Now change one fact. Blake has also died before Alex, leaving no children. The estate still totals $900,000, but every child is gone and only the four grandchildren survive.
Under strict per stirpes, the division still happens at the children’s level:
- Blake’s branch holds a $300,000 share with no one in it to take, which is redistributed according to the state’s rules or passes to Blake’s own heirs if any exist.
- Evan takes Casey’s $300,000.
- Faye, Grace, and Henry each take $100,000 from Drew’s share.
Under right of representation, the empty children’s level is skipped entirely and the estate divides at the grandchildren’s generation:
- Evan, Faye, Grace, and Henry each receive $225,000.
The equal split feels more intuitive to most people, which is why a majority of states have moved toward representation as their default rule when someone dies without a will.
A Third Option: Per Capita at Each Generation
A third method sits alongside these two and shows up often enough in estate documents that it is worth knowing. Per capita at each generation, favored by the Uniform Probate Code and adopted by a growing number of states, starts the same way as right of representation by finding the first generation with at least one living member. Living members at that level each take a share. The difference is what happens to the shares of deceased members at that level: those shares are pooled and redistributed equally among everyone in the next generation down, rather than staying inside each deceased person’s branch.
The result is that every person in the same generation receives the same dollar amount. In the Alex example where all three children have died, per capita at each generation would also give each of the four grandchildren $225,000. The two methods diverge in more complex family trees where multiple generations contain deceased heirs and shares cascade further down. Per capita at each generation keeps recombining and splitting at every level. Right of representation lets each branch’s share travel independently once it starts moving.
Why the Terms Get Confused
Estate planning conversations about these methods go sideways because the same words mean different things in different states and documents. Some jurisdictions use “per stirpes” and “by right of representation” as synonyms. Others draw a sharp line between them. A will that says “to my descendants, per stirpes” might trigger the strict English method in one state and the modern representation method in another, depending on how the local probate code defines the term.
If someone dies without a will, state intestacy law decides which method applies. Most states now use some form of representation rather than strict per stirpes, but the specific flavor varies. Some use per capita with representation, some follow the per capita at each generation approach from the Uniform Probate Code, and a few still default to strict per stirpes. The intestacy rule also fills gaps in wills that name a beneficiary but say nothing about what happens if that person dies first. Many states have anti-lapse statutes that pass the share to the deceased beneficiary’s descendants by representation, but the details vary enough that relying on those safety nets is risky.
Writing It So Your Intent Survives
The safest approach is to never rely on a Latin phrase alone. Spell out in plain English what should happen if a beneficiary dies before you, naming the method and describing the intended result. A clause along the lines of “to my descendants, per stirpes, meaning that if any child of mine predeceases me, that child’s share shall pass equally to his or her then-living children” removes almost all ambiguity. It also protects against a later move to a state that reads the Latin differently than the state where you signed the document.
The choice itself should match how you think about fairness in your family. If you want each child’s branch to receive an equal share regardless of how many grandchildren are in it, strict per stirpes matches that instinct. If you want every grandchild to receive the same amount when they are the ones actually taking the money, per capita at each generation is the closer fit. Right of representation lands between the two.
One more place to apply the same care: beneficiary designations on retirement accounts and life insurance policies. Most custodians let you add “per stirpes” after a named beneficiary. If your daughter is the primary beneficiary of your IRA with a per stirpes designation and she dies before you, her share passes to her children automatically rather than falling back into your estate or to a contingent beneficiary. These forms operate outside probate and outside your will. If the will says one thing and the beneficiary form says another, the form wins. A mismatch between the two is one of the most expensive estate planning mistakes families discover only after it is too late to fix.
