An extrajudicial settlement of estate was created between siblings. Knowing that one of them is adopted, they gave a portion to that sibling anyway.
Everything was already transferred to respective names.
After a year, they found out that the adopted one, didn't undergo the process of legal adoption.
Being aware again, the other siblings did nothing, and for them the ESE is still enforced and it didn't matter because they've always treated that one as real sibling.
Questions, dear fellows:
1. Is the ESE valid?
2. Will there be any consequences in the future?
Thank you for your replies.
