The World Health Organization’s declaration of a global pandemic and in addition, the state of alarm in Spain (Royal Decree 463/2020, of 14 March) along with the continued enactment of abundant, urgent and extraordinary regulations has prompted us to carry out the following actions:

We have reinforced our legal teams specializing in the following areas:

  • Employment and Social Security Law: employment issues; Collective Dismissal Proceedings (Expedientes de Regulación de Empleo) (ERE, ERTE); suspension of employment relations, change in working hours, schedules and telecommuting; contributions, deferrals and unemployment benefits.
  • Contract law, in broad terms and, in particular, regarding the suspension and amendment of clauses and contracts, interruptions, delays, changes in circumstances, cases of force majeure, etc., in civil and commercial agreements, whether national or international.
  • Financial law and refinancing: Debt and credit negotiation, compliance with ratios, defaults, extraordinary circumstances, entitlement to public aid.
  • Tax law, in relation to deferrals, suspended deadlines for tax payments, and amendments in local and regional taxes.
  • Bankruptcy law, voluntary and mandatory insolvency proceedings, pre-insolvency proceedings, involving natural persons, freelance workers, entrepreneurs and companies.
  • Procedural and administrative law, in all matters related to the suspension of deadlines and regulatory amendments in civil, criminal and commercial procedures in all jurisdictions; administrative proceedings and arbitration (national and international), mediation and disputes.


In the interests of our team and to everyone’s benefit, we have limited on-site presence to meetings or interviews that cannot be postponed, where all officially recommended protection and physical separation measures will be adopted.

For telecommuting the entire team has the necessary tools and experience, and cybersecurity measures in place, to allow us to continue providing a smooth and uninterrupted service, with the utmost protection.

All of us at Mavens remain at your total disposal, trusting that this exceptional and temporary situation will be overcome quickly and in the best way possible for our health and interests.


Here are words of encouragement from mavens, everything will be fine.

Main working areas

Business and Entrepreneurship Law

At the Commercial Department we handle the needs of our enterprise clients, providing advice on a broad range of issues, covering both day-to-day business (advice in contractual matters and ordinary corporate activity) and exceptional transactions (sale and purchase of companies and/or undertakings, mergers, spin-offs, segregations, contributions of a branch of activity, etc.). We also advise and assist company shareholders in their mutual relations and with other investee companies, helping them establish devices governing both their co-existence and the terms of their possible exit.

Our professionals have a broad vision of tax law with solid knowledge in taxation (local, regional, international, financial, indirect) and accounting, but also with knowledge in other areas of law (commercial, civil, procedural), which makes our professionals have a joint vision of the situations raised by our clients, a fact that places the Mavens Tax Department as a benchmark in the 360º advice provided to their clients.
