situación de dependencia o de comunidad

00:16 Feb 27, 2021 

I knew that comunidad could not have been referring to comunidad de bienes. Comunidad de intereses makes sense. I am seeing some law articles on community of interest, such the "Community of Interest": Clarity or Confusion? by Joseph J. Fittante Jr. published by the ABA., which notes historic lawsuits in several states in the US addressing the definition. From the looks of it, it is rather confusing with different states' stances and statutes treating that term differently. I am not sure of a better solution than keeping community of interest in my translation. I thought of rendering all 3 of the elements as "economic dependence, community-of-interest or conflict-of-interest situations" but Adrian does point out West's entry of dependencia synonoymous to personal. So I think I am going with "Has never been employed by or had any community-of-interest or conflict-of-interest situations with any of the parties (...)."

A community of interest refers to a group of people with a common set of concerns that may be affected by legislation. Examples of communities of interest include ethnic, racial, and economic groups. Some states require that the preservation of communities of interest be taken in account when drawing electoral districts in an effort to enable these communities to elect representatives whose platforms or policy proposals align with their interests.[

But my doubt still persists: Is "community of interests" the right translation for "comunidad de intereses" as this is to be understood in the Spanish legal system?

“Comunidad” refers here to “comunidad de intereses”, likewise ”contraposición” being the full expression “comunidad de intereses y contraposición de intereses”, abridged “comunidad y contraposición de intereses”.
This query has to do with a statement of non-existence of grounds for challenge of experts (the so-called “declaración de tachas” in Spanish law, Seth mentions this in his text already). Such statements are made by experts in order to rule out any possible grounds for their challenge in civil proceedings. Seth, your text reflects exactly how article 343 of the Spanish Civil Procedure Act 1/2000 reads. The official translation provided by the Ministerio de Justicia reads "situation of dependency or community or conflict of interests".
My only doubt here concerns the rendering of "comunidad de intereses" into US Engish. I am not sure if "community of interests" is appropriate in the US legal system. Anyway, Adrian has suggested something that seems reasonable to me.
