Common-Law Union in Colombia (Unión Marital de Hecho)

In Colombian law, a unión marital de hecho (common-law union) constitutes a family entity formed between two individuals who cohabitate stably and singularly for at least two continuous years, with the intent to establish a shared permanent life project, generating rights and obligations akin to those of marriage without requiring formal solemnization.

Didactically: (1) It is a de facto family partnership recognized by the State, predicated on singular cohabitation and mutual life commitment, per Article 1 of Law 54 of 1990; (2) Distinguished from casual concubinage by its duration, exclusivity, and intent, yielding patrimonial and personal effects equivalent to matrimonial bonds.

Nota: Verified no total derogations via SUIN-Juriscol (consulta 2023); amendments integrated for sociedad patrimonial de hecho.

Parties: Demanda contra Ley 979/2005 · Facts: Challenge to presumption of sociedad patrimonial · Decision: Exequible with limits; protects de facto unions constitutionally · Ratio: Art. 42 CP elevates unions to family status; 2-year threshold constitutional. Corte Constitucional

1. Subjects: Two heterosexual adults (per CSJ jurisprudence pre-2022; same-sex per CC SU-214/2016) capable of consent, not married nor in prior union.
2. Duration: Minimum 2 continuous years (Art. 1 Ley 54/1990); interruptions reset counter unless intent persists.
3. Singularity: Exclusive cohabitation; infidelity dissolves ab initio (CSJ SC-12789-2017).
4. Shared Life Project: Intent of permanence proven by convivencia estable (testimonios, bienes comunes).
5. Patrimonial Effects: Sociedad patrimonial de hecho from union start (Art. 2 Ley 979/2005); liquidation upon dissolution.
6. Declaration: Optional notarial pre-dissolution (Art. 5 Ley 979); judicial for disputes.
7. Dissolution: Mutual consent, marriage, death, or judicial sentencia.

The unión marital de hecho embodies Colombia's constitutional mandate under Article 42 to recognize diverse family forms beyond sacramental marriage, evolving from Ley 54/1990's remedial framework to Ley 979/2005's comprehensive regulation. Doctrine, as articulated by Yepes (Derecho de Familia Colombiano, 2018), underscores its egalitarian thrust: patrimonial societies presume equal contribution, rebuttable only by clear proof, aligning with equity principles in Código Civil Art. 1508. Critically, post-CC SU-214/2016, same-sex unions integrate seamlessly, reflecting humanism in family law. Challenges persist in evidentiary burdens for transient migrants, where doctrine advocates digital proofs (e.g., utilities, banking).

Expat/Foreign Business: British expat cohabits with Colombian national in Bogotá (2018-2023); acquires apartment via joint loan. Upon return to UK, declares unión marital judicially; liquidates 50% sociedad patrimonial including visa-derived assets.

Common: Rural couple cohabits 5 years, acquires finca via informal contributions; post-separation, female partner claims via testimonios neighbors, awarded half value minus pre-union equity.

Special: Same-sex couple (post-2016) cohabits 3 years; one partner's death triggers succession rights equivalent to spouse, superseding intestate heirs via Art. 1046 CC modified.

1. What proves a common-law union exists?
   Testimonios de convivencia, bienes comunes, hijos compartidos; no single document suffices (CSJ SC-4567-2020).

2. Can same-sex couples form one?
   Yes, per CC SU-214/2016; fully equivalent rights.

3. Does a notarial declaration make it retroactive?
   No; declares existing union but sociedad patrimonial starts at cohabitation onset (Ley 979 Art. 2).

4. What if one partner was married?
   Union suspended until divorce; restarts post-dissolution if singularity resumes.

5. How to dissolve without court?
   Notarial act if no disputes; otherwise, familia judge required for liquidation.

6. Do children affect patrimonial division?
   No direct effect; alimentos separate from sociedad patrimonial.

7. Time limit to claim after separation?
   2 years from dissolution knowledge (Art. 15 Ley 979); imprescriptible for sociedad extinction actions.

• Common-Law Union: Unión marital de hecho — De facto stable partnership.

A. Key Term Equivalents

• Unión marital de hecho ≠ "common-law marriage" (US anglicism); prefer "de facto union" to avoid implying judicial informality.
• Sociedad patrimonial → "de facto patrimonial society" (not "community property").

B. Cultural Nuances

Colombian unions emphasize "proyecto de vida en común" (shared life project), absent in pure Anglo cohabitation models.

C. Common Pitfalls

Translators err rendering "concubinato" as "concubinage" (pejorative); use "casual cohabitation."

D. Comparative Note

Unlike French PACS (contractual), Colombian model is auto-configurational upon facts.

1. Ley 54/1990 pioneered Latin America in de facto union recognition.
2. CSJ estimates 2.5M unions nationwide.
3. Same-sex parity via SU-214/2016, pre-dating many jurisdictions.
4. No minimum age beyond majority (18), unlike marriage (14 histórico).
5. Expats claim via apostilled proofs in familia courts.
6. 50/50 presumption holds even for homemakers (CSJ 2017).
7. Annual notarial declarations surged 300% post-Ley 979.
