## Basis
- [Law No. 10.406/2002 (Planalto, in Portuguese)](https://www.planalto.gov.br/ccivil_03/leis/2002/l10406.htm): Article 178 establishes that the decay period for requesting the annulment of a legal transaction is four years, counted according to items I, II, and III.

## How it applies
The general decay rule for the annulment of a legal transaction applies based on the defect or condition of the agent. The calculation of the four-year period begins on the day the duress ceases, the day the transaction was performed (for error, fraud, creditor fraud, state of danger, or injury), or the day the incapacity ceases (for acts by incapacitated persons).

## Limits
- The card covers exclusively the general rule and the hypotheses expressed in Article 178 of the Civil Code.
- Other specific periods provided by legislation for different annulments are not addressed.
- Subsequent changes must be verified in the official Planalto source.
