Automatic summary, not yet reviewed
- The law creates the professional company: a company whose purpose is to jointly practice an activity that requires an official university degree and membership of a professional association. It can use any corporate form allowed by law.
- Its corporate purpose must be exclusively professional, though it may hold shares in other professional companies. It may also practice several professions, unless they are incompatible by law.
- At least three quarters of the capital, voting rights, assets and partners must be professional partners, and so must three quarters of the directors. If this is breached and not fixed within three months, the company is dissolved.
- The company must be registered in the Mercantile Registry and in the Registry of Professional Companies of the relevant professional association. Changes to partners, directors or the company agreement must also be registered.
- The company is liable with all its assets, but the professionals who acted, whether partners or not, are also jointly liable for debts arising from professional acts. This also applies to groups working together without forming a company.
- Existing companies covered by the law must adapt and register in the Mercantile Registry within one year. If they fail to do so within eighteen months, they are automatically dissolved.
Who it affects
- Licensed professionals who want to work together through a company: They must form professional companies and meet the rules on partners, registration and liability.
- Clients and users of professional services: They have more parties liable: the company and also the professionals who performed the work.
- Professional associations (colegios profesionales): They must create Registries of Professional Companies and can exercise their powers over these companies.
- Existing companies already practicing professions jointly: They must adapt to the law and register within set deadlines or be dissolved.
