Legal Definitions - post diem

Post diem is a Latin term that translates to "after the day." In legal contexts, it refers to an action, event, or obligation that occurs subsequent to a specific date or deadline by which it was originally required or expected to happen. Essentially, it signifies that something was done late or past its due date.

• Example 1: Contractual Performance

  Imagine a software development company that signed a contract to deliver a fully functional application to a client by March 15th. Due to unexpected technical challenges, they were unable to complete and deliver the application until March 25th.

  In this scenario, the delivery of the application on March 25th is considered post diem because it occurred after the contractual deadline of March 15th. This late delivery could potentially lead to breach of contract claims or penalties as outlined in their agreement.

• Example 2: Regulatory Filing

  Consider a corporation that is legally mandated to file its quarterly environmental compliance report with a government agency by the 30th of April. However, their legal department submits the report on May 5th.

  The submission of the report on May 5th is post diem because it happened after the official regulatory deadline of April 30th. This delay could result in fines or other enforcement actions by the government agency.

• Example 3: Exercising an Option

  A tenant has a lease agreement that includes an option to renew for another year, provided they notify the landlord in writing by June 1st. The tenant sends their renewal notice on June 5th.

  The tenant's notification on June 5th is post diem because it was sent after the specified deadline of June 1st. As a result, the landlord might argue that the option to renew was not validly exercised, and the lease could expire as originally planned.
