er (before a signature)

Why not post question in the French/French forum?

I wonder if this might provide a clue:

"Signature collective/procuration collective à deux: la personne autorisée à signer ou le fondé de procuration ne peut effectuer les actes juridiques précités qu'avec un associé ou une autre personne autorisés à signer.
D'autres types de signatures, notamment celles de simples mandataires commerciaux (e.r.), ne peuvent pas être inscrites."

Might it possibly stand for "en représentation"?

Thanks for the suggestions, but I checked "er" in this context in the German and no one had any idea what it meant.

Like erstellt/erarbeitet, meaning written.
I'm not sure if this is the same in French, but in German, pp often means on behalf of the company rather than on behalf of someone who is absent. So "er" could be the person who wrote the letter, and "pp" the authorised signatory.
Or this could all be totally wrong.

Just a thought, it might be some German abbreviation — there are loads of words in German that start with 'er-', so it might be the start of a word, rather than the letters E and R (as is the case with 'pp')
