There's not much point leaving in the original Portuguese, unless it is a postal address, as an obscure foreign address may leave close relatives - who don't know any Portuguese - angry and frustrated. It is, again, presumptuous to expect them to, even if Bloco may be obvious - as a non-chocolate product - to readers of Romacne languages.

PS 1. I reserve the right to correct and edit the asker's question: e.g. the descriptive section of the judge's ruling is commonly called the 'operative part of the Decree' /
court ruling granting socio-affective parenthood to relatives = 'court decree granting next-of-kin the day-to-day physical and emotionally close care & control and/or decision-making custody'.

2. A plausible reference has been given, besides which postcodes are often and counter-intuitively reversed to prefix the place name e.g. Praça Marquês de Pombal, *1250-096 Lisboa* might well be misinterpreted by British postal sorting clerks as an LGBT+ building prefixed by a street address and/or postcode.
