A single-owner business entity with its own legal personality under Colombian law. Our corporate lawyers advise on whether the E.U. structure is right for your situation in Medellín.
Contact UsEmpresa Unipersonal (E.U.)
The Empresa Unipersonal (E.U.) is a business entity created under Law 222 of 1995 that allows a single individual or legal entity to establish a company with its own separate legal personality in Colombia. Unlike operating as a persona natural (sole proprietorship without a separate entity), the E.U. creates a distinct legal person — meaning the company has its own NIT, can hold assets, enter contracts, and assume obligations independently from its owner. The owner's liability is generally limited to the capital allocated to the enterprise, providing a degree of asset protection. However, this protection is not absolute: Colombian courts have applied the doctrine of piercing the corporate veil (desestimación de la personalidad jurídica) to E.U. structures in cases involving fraud, commingling of assets, or undercapitalization, which can expose the owner's personal assets to company liabilities.
Since the introduction of the SAS in 2008, the practical relevance of the Empresa Unipersonal has diminished significantly. The SAS offers the same single-owner capability with substantially greater flexibility in governance, capital structure, and operations — and with stronger liability protections under Law 1258. As a result, new E.U. registrations have dropped dramatically, and many existing E.U. entities have converted to SAS structures. The E.U. requires a private founding document registered with the Cámara de Comercio, specifying the owner, business purpose, capital allocation, duration (which may be definite or indefinite per Article 72 of Law 222 of 1995), and the name of the business manager. The Código de Comercio and Law 222 impose specific rules on the E.U. that are less flexible than those governing the SAS.
At Legal Diligence Medellín, we generally recommend the SAS over the E.U. for new single-owner businesses due to its superior flexibility and protections. However, there may be specific circumstances — such as existing E.U. entities requiring ongoing legal support, or particular regulatory contexts — where understanding the E.U. structure remains relevant. Our corporate lawyers can evaluate your situation and advise on the optimal structure. If you currently operate an E.U. and are considering conversion to a SAS, we handle the entire transition process. Schedule a consultation to discuss your options.
Key Requirements
Single Owner (Natural or Legal Person)
The E.U. is formed by a single owner, who may be an individual or a legal entity. If the owner is a company, it cannot already be an E.U. itself.
Founding Document
A private document must be registered with the Cámara de Comercio specifying the owner, business purpose, capital, and duration (which may be definite or indefinite).
Allocated Capital
The owner must allocate specific capital to the enterprise, separating it from personal assets. This allocated capital defines the limit of liability.
Specific Business Purpose
The E.U. must define its business activities with specificity in the founding document. Broad or indeterminate purpose clauses are not permitted.
Benefits
-
Separate Legal Personality — The E.U. has its own legal identity, separate from the owner, allowing it to hold assets, contract, and litigate independently.
-
Single-Owner Structure — No need for additional shareholders or partners — one person can form and control the entire entity.
-
Limited Liability (with Caveats) — Owner liability is generally limited to allocated capital, though courts may pierce the veil in cases of fraud or undercapitalization.
-
Private Document Formation — Incorporation is done via private document rather than public deed, reducing notarial costs compared to SA or Ltda structures.

In almost all cases, the SAS is the better choice for a single-owner business in Colombia. The SAS offers the same single-shareholder capability with greater governance flexibility, broader permitted business purposes, more robust liability protection under Law 1258, and wider acceptance in the Colombian business community. The E.U. was the only single-owner option before 2008, but the SAS has largely superseded it. Our lawyers can confirm whether a SAS is the right structure for your specific situation during a consultation.
Yes, and this is a common transition. The conversion process involves drafting new bylaws under the SAS framework, completing the necessary registrations with the Cámara de Comercio, and ensuring continuity of the entity's contracts, tax obligations, and legal relationships. The specific steps and timeline depend on your E.U.'s current situation, including outstanding obligations, assets, and contracts. Our corporate team handles these conversions regularly and can guide you through the entire process.
The death of the owner of an E.U. has specific legal consequences under Colombian law, including potential dissolution of the entity unless the heirs take action to continue operations or convert the entity within the timeframes established by law. This contrasts with the SAS, where shares are simply transferred through succession. The succession and continuity implications are important considerations when choosing between entity types — something our lawyers can discuss in detail during your consultation.
In principle, the owner's liability is limited to the capital allocated to the E.U. However, Colombian jurisprudence has established that this veil can be pierced when there is evidence of fraud, commingling of personal and business assets, use of the entity to evade legal obligations, or gross undercapitalization. The practical strength of this liability protection depends significantly on how the E.U. is managed and capitalized. Our lawyers can advise on best practices and whether a different structure might offer stronger protection for your situation.
