What we do

Arias SLP is a firm with only one area of practice: dispute resolution


We act as counsel and as arbitrators.

Our team has wide experience in commercial and investment arbitration.

The majority of our cases have an international element: the nationality of the disputing parties, the applicable law or the venue of the proceedings.

In some cases we are the only law firm to assist our clients and in others we act as co-counsel with other firms.


We advise on commercial disputes and insolvency proceedings before all Spanish courts.

We have expertise in litigation regarding tort, energy and natural resources, regulated sectors, banking and finance, leases, construction, agency, distribution, insurance, real estate, corporate litigation, competition, internet and new technologies, retail, telecommunications, transport and logistics.

We also help our clients to set up a multijurisdictional litigation team when needed.
