Does Thai immigration require a Chanote for processing a child's education visa?

In processing a child's education visa in Thailand, it's unclear if the Chanote is always required, as some individuals report being able to use a rental contract instead. However, several commenters shared experiences where they had to present a Chanote along with the owner's ID for their own Non-O visa extensions, indicating that while it may not be universally mandated, it could be part of the checklist provided by immigration.
