Capacity errors create confusion over who acted, by what authority, for whose benefit, and with what consequence. They commonly arise when personal and representative roles are mixed, signatures omit title or capacity, authority is assumed but not documented, institutional actions lack approval records, fiduciary property is treated as personal property, or communications fail to identify the represented interest. A capacity error may not always invalidate an action, but it can create uncertainty, dispute, liability exposure, or administrative correction requirements. Correcting capacity requires records, not slogans.

Capacity errors occur when an action, signature, decision, communication, or record fails to identify the proper actor, authority source, represented interest, or role being exercised.

No record should be accepted as administratively complete unless it identifies:

1. actor (who took the action);
2. capacity (in what role the actor acted);
3. authority source (what granted the power to act);
4. represented interest (for whose benefit the action was taken);
5. action taken (what was done);
6. date (when the action occurred); and
7. signature or attribution method (verifiable evidence of the actor's identity).

If any of these elements is missing, the record is at risk of capacity error.

Capacity error doctrine identifies the defects that undermine accountable administration. Key elements include:

• Capacity Error: A defect in which the record does not clearly identify the actor's role, authority source, or represented interest. Capacity errors may be formal (missing capacity designation) or substantive (acting without actual authority).
• Unclear Authority: When the record does not cite the source of authority for an action, it may be impossible to determine whether the action was authorized.
• Unauthorized Acts: Actions taken without authority are generally voidable. The actor may be personally liable; the represented party may not be bound.
• Signature Defects: Signatures lacking capacity designation ("John Doe" instead of "John Doe, Trustee") create ambiguity about whether the signer acted personally or in a representative capacity.
• Personal Liability Risk: When a fiduciary acts without proper capacity identification, they may be treated as acting personally, exposing personal assets to liability.
• Fiduciary Record Confusion: Commingling fiduciary and personal records makes it impossible to trace which assets belong to the fiduciary estate and which are personal.
• Institutional Attribution Failure: When an officer acts without identifying the office, the action may be attributed to the individual rather than the institution.
• Commingling of Roles: Using the same signature block, email account, or communication channel for both personal and institutional business creates confusion.
• Corrective Documentation: Some capacity errors may be corrected through clarifying records: ratification, ratification instruments, clarifying memoranda, or corrected signature pages.
• Ratification Where Applicable: A principal may ratify an unauthorized act if the act was within the principal's power and the principal has full knowledge. Ratification must be documented.
• Limits of Correction: Correction may be impossible where third parties have relied on the defective record, or where the error cannot be cured without rewriting history.

• General agency principles concerning authority and attribution – An agent's authority is defined by the principal's manifestations; actions outside authority may be unauthorized.
• Restatement (Third) of Agency – An agent who acts without actual authority may be personally liable to third parties. Unauthorized acts do not bind the principal.
• Restatement (Third) of Trusts – A trustee must act within the scope of trust authority; unauthorized acts may result in surcharge or removal.
• Uniform Trust Code § 801 – A trustee has a duty to administer the trust, which includes acting within the scope of authority.
• Uniform Trust Code § 802 – The duty of loyalty restricts actions that benefit the trustee personally; capacity confusion may trigger loyalty review.
• Uniform Trust Code § 810 – A trustee has a duty to keep trust property separate and identifiable. Commingling is a capacity error with serious consequences.
• Uniform Trust Code § 813 – A trustee has a duty to inform and report, which requires clear identification of the capacity in which information is provided.

These authorities reflect broadly recognized agency, fiduciary, trust, and governance principles. Specific consequences depend on jurisdiction, governing documents, facts, transaction type, reliance by third parties, and available correction procedures.

• Trust Administration: Trustee signatures should identify trustee capacity ("John Doe, Trustee"). Trust property should be separated from personal property; commingling is a serious capacity error. Trust records should identify the trust relationship and distinguish trust assets from personal assets.
• Institutional Governance: Officer action requires authority documented in resolutions or bylaws. Resolutions should identify role and approval. Institutional correspondence should identify office capacity.
• Administrative Process: Notices must identify sender capacity (e.g., "Office of the Fiduciary"). Records must show authority. Review requires proper attribution linking actions to authorized actors.

• Capacity statement (clear identification of role).
• Authority document (appointment, resolution, delegation).
• Governing instrument (trust, bylaws, articles).
• Signature block (with capacity designation).
• Role assignment (who holds what authority).
• Resolution or approval (documentation of authorization).
• Communication record (emails, letters with capacity).
• Transaction record (signatures, dates, capacity).
• Correction memorandum (documented correction of capacity error).
• Ratification record where applicable (principal's ratification of unauthorized act).
• Final review record (confirmation that capacity error has been corrected).

Core rule: If capacity is not recorded, it may be treated as personal. Documentation is the evidence of representative or institutional capacity.

• Signing without title or capacity designation.
• Acting before authority is granted and documented.
• Using personal accounts for fiduciary activity (commingling).
• Unclear email signatures that do not identify role.
• Failing to distinguish trust from trustee – the trust is the entity; the trustee is the officeholder.
• Assuming verbal authority is enough – undocumented authority is difficult to prove.
• No approval record – acting without documented approval.
• No correction record – failing to document correction of capacity errors.
• Relying on intent instead of documentation – intent cannot substitute for record attribution.

KLI teaches capacity errors because administrative confusion begins where capacity is unclear. Authority must be identified before consequence can be properly assigned. Record integrity preserves accountability. Organizations that document capacity consistently reduce confusion, protect against personal liability, preserve institutional records, and maintain accountability. Capacity errors are not merely formal defects; they are governance failures that undermine the ability to trace actions to authorized actors. Proper capacity identification is a governance requirement, not a bureaucratic preference.
