Cohabitation (unión convivencial)

Living together has legal effects too. We explain your rights and obligations, and how to protect yourself.

Many couples choose to live together without marrying. Argentina’s Civil and Commercial Code recognizes these relationships as registered cohabitation (uniones convivenciales) and gives them certain legal effects, different from those of marriage.

Knowing them in good time avoids surprises: for example, what happens to the family home, how household expenses are shared or what becomes of property if you separate. Couples can set out several of these matters in a cohabitation agreement.

Our team explains clearly how it works, helps you register your relationship or draft the agreement, and supports you if the relationship ends and there are issues still to resolve.

How can we help?

  • Registering your cohabitation.
  • Drafting a cohabitation agreement.
  • Protecting the family home.
  • Resolving what happens when the relationship ends: the home, property and economic compensation.
  • Care and support of shared children.

Frequently asked questions

Is it the same as being married?

No. A unión convivencial has certain legal effects of its own, but they differ from those of marriage — for example, regarding property and inheritance.

Why register the relationship?

Registration makes it easier to prove that you live together and allows you to protect the family home against third parties.

What is a cohabitation agreement?

It is a written agreement in which the couple sets out matters such as contributions to household expenses or how property will be divided if the relationship ends.
