Contrato Social Inclusão de Sócio Template for Brasil

When your company needs to bring in a new partner, the Contrato Social Inclusão de Sócio is the essential legal document that formalizes this business relationship in Brasil. This partnership inclusion agreement legally establishes the new partner's rights, obligations, and ownership stake while updating your company's corporate structure according to Brazilian commercial law.

When do you need this document?

You'll need this contract whenever your existing business partnership decides to expand by adding a new member to the ownership structure. Common situations include bringing in an investor who wants equity participation, adding a key employee as a partner, incorporating a family member into the family business, or merging with another entrepreneur who will contribute capital or expertise. The document is also required when converting from a sole proprietorship to a partnership, or when restructuring ownership percentages among existing and new partners.

Key legal considerations

The contract must clearly define each partner's capital contribution, whether in cash, assets, or services, and specify the exact ownership percentage each partner will hold. You need to establish voting rights, profit distribution mechanisms, and management responsibilities for the new partner. Consider including clauses about partner withdrawal procedures, dispute resolution mechanisms, and restrictions on share transfers to third parties. The agreement should also address the new partner's liability for existing company debts and obligations, as well as their role in future business decisions and daily operations.

Legal requirements in Brasil

Under Lei nº 10.406/2002 (Código Civil), all partnership modifications must be properly documented and registered with the local Junta Comercial.

You must detail the updated share capital distribution and ensure compliance with Instrução Normativa DREI nº 81/2020 for proper commercial registry filing. The document needs notarization and must be submitted to the Junta Comercial within 30 days of signing. For smaller companies, additional requirements under Lei Complementar nº 123/2006 may apply, particularly regarding simplified procedures for micro and small enterprises.
