The margin note reads "1.a verba extrahida em 14 de Junho de 1823 [signed] (modern spelling without abreviations: Primeira verba extraida em 14 de junho de 1823)
Google translate offers this as "first sum extracted on June 14, 1823" but I suspect "verba" is actually a more flexible word. In this case it probably just means a legal certificate was made of this record on this date. There are many reasons a certificate might be needed such as inheritance, getting married, getting a passport, for examples. There are probably many other reasons.
I hope this helps.
