Memoir, Life Story or Autofiction: Which Pact With the Reader?
Memoir promises the reader that everything happened as told and can be checked; autofiction tells your life under the label of a novel and allows itself to invent wherever memory or meaning demand it; the life story sits between the two, faithful to the facts but free in form. Three pacts, three different promises to the reader, and the choice is made before the first page, not after. The word "autofiction" was coined by Serge Doubrovsky for his book Fils in 1977; since then it has named a grey zone this article tries to make workable.
The three pacts in one sentence each
The pact is what the cover and the first pages promise. A reader forgives a novel what they will not forgive a memoir.
| Pact | Promise | What the reader expects |
|---|---|---|
| Memoir | "Everything I tell happened, the way I tell it." | Facts, dates, real names |
| Life story | "Everything happened; I chose, tightened, sometimes renamed." | True facts, free form |
| Autofiction | "This is a novel; I am in it, and I won't say where the truth ends." | A reading experience, not testimony |
What each pact allows you to do
A concrete question: two summers have merged in your memory, the one when your father left and the one, two years later, when your grandmother died. Can you make them a single summer in the book?
| Freedom | Memoir | Life story | Autofiction |
|---|---|---|---|
| Change a relative's name | No, or with a note | Yes | Yes |
| Merge two summers into one | No | No (but you can set them side by side) | Yes |
| Invent dialogue you don't remember | No: you write that you don't recall | Rebuild the spirit, not the words | Yes |
| Change the ending | No | No | Yes |
The life story is the most common pact among people writing for their family: the full method is in how to write a memoir that reads like a novel. Autofiction is the pact of those who want a book before a testimony.
The same memory under three pacts
An invented scene: the narrator, aged ten, watches her father load a suitcase into the car.
Memoir:
On July 12, 1984, my father put a blue suitcase in the trunk of the Renault. My mother was at work. I don't remember what he said to me. I know he came back ten days later.
Life story:
One July morning my father loaded the blue suitcase into the trunk. He said something like "I'll be back soon," and he did come back, but later than he had promised.
Autofiction:
Lise's father loaded the blue suitcase, then turned around and said: "Tell your mother she started it." Lise told her mother nothing. She told nobody for eleven years.
All three are legitimate. Only the third invents a line and an eleven-year silence. It is also the strongest, and that is the trap: autofiction makes life more readable than it was. That is not a fault, provided the book announces itself as a novel.
Examples on both sides of the Atlantic
In English, Mary Karr's The Liars' Club holds the memoir pact, and Sheila Heti subtitles How Should a Person Be? "a novel from life," which is exactly a declaration of pact. In French, Annie Ernaux writes in The Years a collective autobiography without "I," where every detail can be checked, and Édouard Louis, in The End of Eddy, keeps the facts and reframes them as a novel. The work on language these books share is discussed in writing literary fiction.
What the pact changes for other people
The pact also protects the people you write about. "My brother" in a memoir commits your brother; "Lise's brother" in autofiction leaves him a way out, without guaranteeing it. The legal and ethical landmarks are detailed in writing about real people. Moving a street or renaming a village is a pact decision too, as explained in real places as fiction.
In the Sagoræ workshop, the pact fits on one line at the top of the outline, and Théo rereads it with you when a scene slides from one pact to another: he asks the question, he does not decide, and he writes nothing.
Decision grid
- Do you want the reader to be able to verify every fact? Yes: memoir.
- Are you willing to rename relatives without saying so? Yes: life story or autofiction.
- Do you need to merge, move or invent scenes for the book to hold together? Yes: autofiction.
- Is the book first of all a testimony (for the family, for the record)? Yes: memoir or life story.
Yes to questions 1 and 4: memoir. Yes to questions 2 and 3: autofiction. Everything else is a life story, the most flexible pact for a first book.
Frequently asked questions
What is the difference between memoir and autofiction? Memoir promises that everything is true and checkable. Autofiction presents itself as a novel in which the author appears, and allows itself to invent without saying where.
Can you change names in a memoir? You can, but you must tell the reader (an author's note is enough). Without that signal, you are already writing a life story.
Do you have to choose the pact before writing? Yes. It decides what you are allowed to do in every scene, and switching pacts midway forces you to rewrite a large part of the book.
If you want a workshop where your pact stays written at the top of your outline and the coaches ask questions without ever writing in your place, Sagoræ offers a free trial, no card required.
