ILLUSTRATIVE CASE · FICTITIOUS DATA · DOES NOT DESCRIBE A REAL CUSTOMER

01

Context

A company was about to enter into a high-value contract.

02

The decision that was at stake

Confirm that the signatory validly binds the counterparty.

03

Reviewed evidence

  • Complete power of attorney and instrument details.
  • Economic limit applicable to individual action.
  • Express rule of joint signature above the limit.
  • Contract value greater than the expected threshold.

04

Find

Power required joint action above an economic limit that the contract exceeded.

05

Prudent analysis

The company existed and the agent was real, but the form of exercise did not cover the proposed individual signature.

The finding was separated from any unproven inferences and was evaluated only against the decision presented.

06

Proportional alternatives

  • Obtain the joint signature required by the power of attorney.
  • Request a new sufficient power of attorney or corporate resolution.
  • Ratify the act through the competent body before executing.

Action considered: Request the second signature or sufficient corporate ratification.

Case lesson

What changes a well-contextualized investigation?

The fact that the person is a representative does not mean whether he or she can celebrate that specific act. Type of power, limits, validity and form of exercise must be read.

Practical application

What to check and what to ask

Control questions

  • What decision should this review inform?
  • What evidence confirms the data?
  • What limits should be expressed?

Frequent errors

  • Search without a defined purpose.
  • Confusing a coincidence with a confirmed fact.
  • Ignore date, source or status of the result.

Scope and limits
