Never, because it's not under her custody. It's in a government archive.

She and I both have lost personal ID cards many times though. I have lost passports, and I even lost a document called "Family book" that the Spanish government issues, where info on your birth, your marriage, children and death are registered (but not the original documents, which are in a centralized archive, as I said). Quite big.

I had to ask the government to re-issue all of those, including this last one, which was quite painful, but they just did it because they kept the originals.

Ditto for my mom's house ownership papers.
