Please tell me who has a child (15 years old) independently crossed the border of Thailand, what documents are required? A foreign passport - is it clear that an agreement from one parent is enough?

Passport, birth certificate, notarized permission from both parents. So it was 2 years ago, they didn't ask anything else. I also took my Russian passport with me.

How can a minor cross borders himself?
