Partnership and business formation laws in Portugal.

Default partnership rules in Portugal

In a Portuguese sociedade em nome coletivo (general partnership), profits are distributed proportionally to each partner's capital contribution by default (CSC Art. 22). Partners are jointly and severally liable for partnership debts, but only after the partnership's own assets are exhausted (benefício de excussão). The partnership must be registered in the Conservatória do Registo Comercial. A partnership agreement (contrato de sociedade) can modify the default profit split.

In Portugal, profits are split proportionally to capital contributions by default. This means a partner who invested 80% of the capital would receive 80% of the profits. While this may seem more intuitive than the equal-split default in some countries, it still fails to account for non-cash contributions like time, expertise, and relationships. A written partnership agreement should address all types of contributions.

Sociedade por Quotas (Lda) in Portugal

The Lda (Sociedade por Quotas) is the standard entity for Portuguese startups. Since 2011, the minimum capital is just €1 per quota holder. Through the Empresa na Hora program, a company can be formed the same day at a one-stop shop for €220. Standard formation costs €220–€360. Quota transfers require a written agreement and registration but not notarization. The articles of association (pacto social) govern the company. A shareholders' agreement (acordo parassocial) is recommended for multi-founder companies.

Without a shareholders' agreement, the relationship between founders is governed by the country's default rules, which rarely account for the realities of a startup — where contributions change over time and early effort often goes uncompensated. An operating agreement or shareholders' agreement is essential. Use our equity calculator to determine a fair split based on actual contributions.

What happens when a partner leaves in Portugal

In a sociedade em nome coletivo, a partner can withdraw with adequate notice as provided in the partnership agreement. For Lda companies, quota transfers do not require notarization but must be in writing and registered. Existing quota holders have pre-emption rights by default. Minority quota holders representing at least 10% of capital can request judicial dissolution or a special audit.

A written agreement should address departure terms specifically, including how the buyout value is calculated, the payment timeline, vesting schedules, and any non-compete provisions. Understanding the concept of dead equity is important for managing these situations. Learn more about how dead equity affects businesses.

Marriage and business equity in Portugal

Portugal uses comunhão de adquiridos (community of acquisitions) as the default matrimonial regime. Assets acquired during the marriage are community property and divided equally on divorce. Pre-marital assets, inheritances, and gifts remain separate. Business interests acquired during the marriage are community property. A pre-nuptial agreement (convenção antenupcial) can switch to separação de bens (separate property). The agreement must be registered to be effective.
