preavisos

Preaviso, also known as notice period in English, is a legal requirement in many employment and contractual agreements that obligates one party to give advance notice before terminating a contract or changing its terms. The term is derived from the Spanish prefix pre- meaning before, and aviso meaning notice. A preaviso typically specifies a minimum duration, such as two weeks or one month, that an employee must inform an employer or a customer must inform a provider before the contract ends. This requirement is designed to protect both parties by allowing time to arrange a replacement, complete pending work, or negotiate new terms.

In labor law, preaviso is often mandatory in the event of dismissal, resignation, or lay‑off, and the length can vary depending on the employee’s tenure and the jurisdiction. Some jurisdictions also require a financial compensation equivalent to a certain number of days’ wages if the notice period is not observed. Employers may likewise be subject to preaviso obligations when terminating contracts with suppliers, tenants, or contractors. For instance, real‑estate leases often contain a 90‑day preaviso clause allowing tenants to vacate the premises with two months of notice. In service agreements, a 30‑day preaviso may be stipulated for cancellation of subscription services.

The enforceability of preaviso clauses depends on local regulations. In many civil law countries the preaviso is considered a fundamental fairness principle and courts interpret it strictly. In common‑law countries, the clause may be subject to contractual freedom, but certain statutory minimums still apply. Violating a preaviso can result in damages, reinstatement claims, or claims for liquidated damages. Thus, both employers and employees should carefully review preaviso obligations and negotiate clear terms to avoid disputes.
