o chão caiu para o Autor
"... a Requerida confessou que já fez uso de entorpecentes e drogas ilícitas, inclusive comercializando-as quando era menor [de] idade juntamente com seu ex-namorado, momento em que o CHÃO CAIU PARA O AUTOR."
As per Google Translate:
o chão caiu: the floor fell
I found just one example with "the floor fell":
"He was on the very same pace last year and then the floor fell for him after Christmas."
What do you guys think of "the earth cracked under the Plaintiff's feet"? (I think the idea here is to show how shocked he was by the revelation.)

his world fell apart
900,000 hits on google, and that's only with the pronoun "his".
| Thank you. I think your translation fits the bill. Nothing wrong with "plaintiff". According to M. M. de Castro, that's the term to be used in civil procedures. See my note on the DB. |

Discussion
Suggestion, in that case : leading to/causing/which was a landslide for the plaintiff/petitioner
http://www.aecainlaw.com/blog/petitioner-vs-respondent-in-di...
You will see "plaintiff" used, but "petitioner" is more common and more appropriate. Likewise, we normally say "respondent" rather than "defendant".
autor. 1 – (processo civil) plaintiff; claimant.
