Chosen addresses, plural, addresses of BOTH parties, usually

1- Élection de domicile / Elected domicile

"Élection de domicile. Choix d'un lieu où une partie sera réputée domiciliée pour l'exécution d'un contrat. (...) " (Cornu, Vocabulaire juridique).

Compare with:

"Elected domicile: A contractually agreed domicile between parties for purposes of the contract." (Black's Law Dictionary).

Both of the above definitions indicate that an elected domicile is deemed to exist as between the parties in the context of the contract. And domicile is a substantive concept which, in my view, may have more serious consequences than the mere fact that one has an "address for service" in the jurisdiction. I readily acknowledge that "address for service" is the boiler-plate clause in common law contracts, in which "election of domicile" clauses are rare at best. However, I believe we are dealing here with slightly differing legal customs, whose specificities should not be discounted too quickly. At least in so far as the Black's Law Dictionary defines "elected domicile", I would prefer it as a closer equivalent of "élection de domicile".

(Interestingly, the ECHR, in its decisions on cases originating from Italy, systematically translates "domicilio eletto" in English by "elected domicile", maybe out of recognition of the specificity of the civil law notion of "election of domicile" - e.g., search exact phrase: "elected domicile" at http://www.bailii.org/form/search_cases.html).

2- Élection de for / choice of forum

"Choice of forum" seems to be the most common expression.

That being said, other possibilities would be:

(a) "forum selection":

- "forum-selection clause. A contractual provision in which the parties establish the place (such as the country, state or type of court) for specified litigation between them." (Black's Law Dictionary);

- "A forum selection clause in a contract with a Conflict of Laws element allows the parties to agree that any litigation resulting from that contract will be initiated in a specific forum." (http://en.wikipedia.org/wiki/Forum_selection_clause).

(b) Choice of court:
In line with the recent Convention du 30 juin 2005 sur les contrats d'élection de for / Convention of 30 June 2005 on Choice of Court Agreements, of the Hague Conference on Private International Law (http://www.hcch.net/index_en.php?act=conventions.text&cid=98...
