# Successor Custodian
**Domain:** Continuity Governance / Succession / Custody
**Doc Type:** Canonical Institutional Role
**Maturity:** Proposed
## Definition
A **successor custodian** is an institution authorized and capable of assuming defined continuity duties from a retiring, failed or displaced custodian without acquiring ownership of the subject.
## Qualification
Qualification requires compatible infrastructure, audited preservation and security controls, financial capacity, recognized jurisdiction, transferable credentials, service-level capability, conflict safeguards and acceptance of the existing continuity instrument. A technically capable buyer is not automatically a lawful successor.
The successor receives custody, provenance, keys, service obligations, unresolved claims and duty records through [[wiki/Orderly Transfer|Orderly Transfer]]. It should not receive undisclosed authority to modify, merge, activate or represent the subject. Those powers remain separately governed.
The transfer must also carry the operative [[wiki/Continuity Election|Continuity Election]], its version and supersession history, and evidence connecting it to the protected state. The successor accepts existing limits; acquisition of the provider or archive is not a new consent event.
## Succession Design
Successors should be identified and tested before failure. [[wiki/Multisovereign Custody|Multisovereign Custody]] and [[wiki/Jurisdictional Redundancy|Jurisdictional Redundancy]] reduce correlated failure. If no prequalified successor is available, a [[wiki/Hosting Provider of Last Resort|Hosting Provider of Last Resort]] supplies temporary continuity.
## Key Insight
**Succession transfers duties and protected state, not title to the person whose existence those duties support.**
