The answers provided on that page were never decisive for me because the Ley de Alquileres posted on all of the agency sites had said exactly the opposite, that the rents had to paid in "moneda de curso legal." The laws posted from the civil code by Attorney in BA are general, and could be applied to nearly any contract signed. But given the Ley de Alquileres tackles the subject directly, I always regarded its line about paying in the legal tender as having supremacy.
After reading St. John's post, I noticed that commas and periods were misplaced, which changed the meaning of the copy of the law he posted. So, I decided to go look for it on a government site, which I probably should done in the first place.
As it turns out, the second paragraph--the paragraph that talks about payment being only in the moneda de curso legal--was
stricken down by the Ministry of Economy in 1993 after reviewing a law passed in 1991.
Original law here.
According to
Resolution 144/93, which specifically mentions rentals, landlords can use any currency they wish to use. The most important part: "Artículo 1º — Interprétase que la Ley 23.928 ha derogado el segundo párrafo del artículo 1º de la Ley 23.091, pudiendo las partes contratantes determinar la moneda de pago de los alquileres o arrendamientos que acuerden." (In other words, the second paragraph of the original law no longer applies, and now the parties signing the contract may use whichever currency of payment that they choose.)
My bad for not using official government sites to research this topic better. I think it is safe to say that it is not a general rule, St. John. It seems that it is, in fact, legal to require payment in dollars.
