The IDD field built its long-term planning architecture around a word that named the wrong moment. "Succession" describes a transfer of title. What families of children with disabilities actually live through is a transfer of judgment, knowledge, attention, and relationship — and that transfer cannot happen at a moment. It has to happen slowly, while the parent is still there to hand it over.
The parent was not the planner. The parent was the plan.
If that sentence is true — and the field's instruments confirm it every time they treat the parent's continued presence as the unstated default — then a second sentence follows, and the second sentence is the one this essay was written to argue. If the parent was the plan, then the moment of her departure was never going to be the moment the plan transferred. The plan was thirty years of her attention. Nothing transfers in a moment that took thirty years to build.
This is what the field got wrong when it named the work. We called it succession planning. We borrowed the word from trusts and estates, from corporate governance, from the law of fiduciary office, where succession is exactly the right word — there is a title, there is a holder, the title passes to the next holder upon a triggering event, and the law's job is to specify the trigger and the next holder cleanly. The instruments we used were drawn from that body of law. The vocabulary came along with the instruments. We did not stop to ask whether the vocabulary fit what we were actually doing.
It did not fit. It still does not.
Consider what a successor trustee provision actually says. It says: upon the trustee's death, resignation, or incapacity, the named successor shall serve as trustee. The provision is event-shaped. It specifies a triggering event and a transfer of office. It assumes that the office can be discharged by the successor on the day after the triggering event in roughly the same way it was discharged on the day before. For a financial trustee managing a portfolio against an investment policy statement, this assumption is approximately true. The successor reads the policy, reviews the holdings, consults the advisors, signs the forms. The office transfers.
For a parent serving as trustee of a special needs trust for a nonverbal adult son, the assumption is so far from true that calling it an assumption flatters it. The successor trustee inherits the legal authority to write checks from the trust. The successor trustee does not inherit the parent's twenty-year understanding of which weeks her son sleeps badly because of seasonal change rather than a medication problem, which therapist's manner he tolerated for six months in 2019 before they had to change, which provider's intake form will trigger a meltdown if it is filled out in his presence, which brand of underwear he will accept and which he will not. The legal authority transfers in a moment. The judgment that makes the authority useful does not transfer at all. It was never written down. It lived in one person.
The same is true of every "successor" role the field has built. The successor conservator inherits the court's grant of authority over the conservatee's person, and inherits nothing of the parent's accumulated read on her son's actual capacities — the ones he showed at home with the lights low and the routine intact, not the ones he showed in the cold room with the evaluator he had never met. The successor agent under a power of attorney inherits the document. The successor caregiver inherits the schedule. The successor decision-maker inherits the title. None of them inherits the thing the parent was actually doing.
What the parent was actually doing was running a continuous interpretive operation, calibrated daily, on a person whose communication required calibration. The operation does not have a discrete output that can be handed across at a transfer point. The output is the operation. The operation cannot be transferred. It can only be reproduced, slowly, by another person doing the same operation alongside the parent until the operation lives in two heads, and then in three, and then continues running when the parent's head is no longer there.
That is not succession. That is something else, and the field needs a different word for it.
The field has been looking for the wrong kind of solution because it has been using the wrong kind of word. A succession problem looks like a documentation problem: write down what the successor needs to know, train the successor on the documentation, name the successor with sufficient specificity in the operative instrument, and the transfer will work. The letter of intent is the field's clearest expression of this theory. It is a document the parent writes — sometimes for years, sometimes in a final feverish push when a diagnosis arrives — that tries to compress into prose the entire interpretive operation she has been running. The forty-three-page letter of intent on the desk in my office on the Wednesday afternoon was the best version of this instrument I have ever seen. It was still inadequate to its purpose, and the mother who wrote it knew.
She knew because she had tried to use it. She had given a draft to her sister, who would be the successor caregiver, three years before. The sister had read it, asked thoughtful questions, taken notes. Six months later, when the mother went into the hospital for a knee replacement and the sister stayed at the house for ten days, the document had been useless in the way that mattered most. The sister had it in front of her and could not use it. The information was there. The judgment about which piece of information applied to which moment was not. The judgment had never been in the document. It had been in the mother, applying the information to the moment.
A succession-shaped solution cannot fix this, because the problem is not that the documentation is incomplete. The problem is that the documentation is the wrong instrument for what needs to be transferred. You cannot write down a calibration. You can only do a calibration, in the presence of someone learning to do it with you, for long enough that the calibration becomes theirs.
This is the move the field has not made. It has produced better and better documentation — more thorough letters of intent, more detailed care plans, more sophisticated person-centered planning frameworks — without ever questioning whether documentation was the right form for the work. The field's instruments improved. The field's frame did not. The frame told us we were doing succession planning, and succession planning is improved by better documentation, so we improved the documentation. Decades of effort went into making a wrong instrument more precise.
What the field should have been doing, for the entire time it was perfecting its documentation, was something different in kind. It should have been treating the transfer of the parent's interpretive operation as a multi-year process that begins long before any triggering event and runs continuously until the parent is no longer the operator. It should have been calling this what it is: a transition, not a succession. A transition has duration. It has phases. It has a period during which two people are running the operation together, and a period during which the new person is running it under the old person's supervision, and a period during which the old person is consulted only on hard cases, and a period during which the old person is gone. None of those periods can be skipped. None of them can be compressed past a certain point. None of them is a moment. All of them are the work.
This is why the publication uses the phrase Transition Planning, Not Succession Planning. The phrase is not a stylistic preference. It is the field's foundational conceptual error, named in five words. The instruments the field built — successor trustee, successor conservator, successor caregiver, successor decision-maker — were not wrong to specify the eventual holder of authority. They were wrong to behave as though specifying the holder was the work. The work was the multi-year operation that puts the holder in a position to actually hold the thing. The instruments were the last step of the work. The field treated them as though they were the work itself.
The cost of this category error has been borne, predictably, by parents. They were told that if they got the documents right, the plan would work. They got the documents right. The plan did not work, because the plan was never the documents. The plan was the parent. When the parent was no longer there, the documents did what documents do: they specified the next holder of the title. The next holder of the title did not know what the title was actually for. The interpretive operation stopped. The adult child, in the worst cases, ended up worse off than the parent had spent her entire life trying to prevent. In the better cases, a sibling or a friend or a paid coordinator slowly and painfully reconstructed something approximate over a period of months or years, during which the adult child was the one absorbing the cost of the reconstruction.
This is not a failure of the documents. It is a failure of the frame that put the documents at the center.
It is worth being precise about what is and is not being claimed here. The legal instruments are necessary. A special needs trust without a competent successor trustee provision is not a special needs trust; it is a future crisis. A conservatorship without a successor conservator is not a conservatorship; it is a future court proceeding under emergency conditions. The instruments do what they do, and what they do is necessary, and the field is right to build them carefully.
The claim is that the instruments are not sufficient, and that the field has spent fifty years acting as though they were. The succession-shaped instruments specify who holds the office. The transition-shaped work — the work the field has not had a name for — produces a person capable of holding the office in a way that serves the adult child. The first work without the second produces a title without a holder.
The field has been producing titles without holders for as long as it has been a field, and it has been calling the titles plans.
The vocabulary made this hard to see. "Successor trustee" sounds like a person who will hold a position. It is a person who will hold a position. The trouble is that the position, as held by the parent, was never just the position. It was the position plus the operation. The vocabulary names the position and is silent about the operation. The silence is what the field needs to break.
The mother on the Wednesday afternoon did not know any of this in these words. She knew it in the form she had access to, which was the form of her own exhaustion and her own foreknowledge of her sister's coming exhaustion and her own grief, already beginning, for the operation she had run for twenty years and was now going to have to stop running before her son was ready and before her sister was ready and before anyone was ready, because the operation was tied to a body and the body was sixty-eight years old and tired.
She did not need the field to give her a better letter of intent. She had a letter of intent that was, by any measure the field had been using, excellent. What she needed was for the field to have spent the previous fifteen years helping her run a transition rather than helping her draft a succession. She needed her sister to have been in the operation for a decade, not reading about it for an afternoon. She needed the paid providers to have been integrated into the interpretive work rather than serving it from outside. She needed the conservatorship process, when it came, to have been informed by years of shared observation rather than by a single hearing in a cold room. She needed the trust to have had a co-trustee for the last ten years, not a successor trustee for the next ten. She needed, in short, a framework that had treated her departure as a process to be lived through rather than an event to be planned for.
The field did not give her that. The field gave her the documents. The documents were the best the field knew how to build inside a frame that called the work succession. The frame was wrong. The documents were inside the frame. She was inside the documents. Her son was inside her.
That is the structure the publication exists to name. The instruments stay. The frame has to change. The word at the center of the frame — succession — has to be replaced with the word that describes what was actually needed all along.
The replacement is not cosmetic. Changing the word changes what counts as the work, which changes what counts as competence in doing the work, which changes who the field trains and how, which changes what the parent across the desk is told when she asks what to do. Under the succession frame, she is told to get the documents right. Under the transition frame, she is told that the documents are necessary and that the documents are roughly the last ten percent of what she actually needs to be doing, and that the other ninety percent — the slow induction of other people into the interpretive operation she has been running alone — should have started years ago and needs to start now.
That is a harder thing to tell her. It is also the true thing. The field has owed her the true thing for a very long time.
