Spanish Court Affirms Agent’s Right to Compensation for Client Retention Post-Contract
The Audiencia Provincial de Madrid ruled in 2026 that an agency contract’s termination does not automatically forfeit an agent’s right to compensation for clients retained by the principal, according to a legal analysis of the case. The decision, which upheld a lower court’s ruling, underscores the importance of proving “ventas sustanciales” under Spain’s Ley de Contrato de Agencia (LCA), Article 28.
What Triggered the Legal Dispute?

Diberco 2013, S.L., an agent, claimed Iberdrola Clientes S.A.U. and Iberdrola Servicios Energéticos S.A.U. owed it compensation for clients acquired during its agency relationship. The contracts, which ended in 2018, required the agent to promote electricity and gas services. Diberco argued that the clients it recruited continued to generate revenue for Iberdrola, despite high sector-wide churn rates.
How Did the Court Evaluate Client Retention?
Iberdrola appealed, citing a “high switching rate” of clients and the company’s brand prestige as reasons to deny compensation. However, the Audiencia Provincial rejected these arguments, stating that the LCA’s Article 28 does not exempt principals from paying indemnification if clients remain with the company post-termination. The court emphasized that the contracts already accounted for “early exits” by limiting commissions for cancellations within 2–3 months, which adjusted the agent’s remuneration.
Why Does This Ruling Matter for Agency Contracts?
The case clarifies that an agent’s right to compensation hinges on demonstrating that clients retained after the contract ends contribute to the principal’s future revenue. The court noted that Iberdrola’s brand recognition, while advantageous, does not negate the agent’s entitlement if the contract’s terms and performance are met.
What Are the Implications for Businesses and Agents?
The decision reinforces that agency agreements must explicitly address client retention and compensation structures. For agents, it highlights the need to document client retention metrics and contractual terms. For principals, it underscores the importance of negotiating indemnification clauses that reflect sector-specific risks, such as high churn rates.
How Can Parties Navigate Similar Disputes?
Legal experts recommend that agents retain detailed records of client acquisition and retention, while principals should review contract terms to ensure they align with industry standards. The Audiencia Provincial’s ruling also suggests that courts will prioritize contractual obligations over general market conditions when assessing indemnification claims.
What’s Next for Agency Law in Spain?
The case adds to a body of jurisprudence clarifying the scope of Article 28. The ruling may prompt businesses to revisit agency agreements to mitigate future conflicts.
