Reader question: Names of your parents when buying a condo?

Dear Egbert,

If you are officially registered in Thailand (eg Yellow House Book) your lineage will always be registered. The same applies if you buy a condo.

It's in the law. So my father and mother are also registered in my yellow house book. Officially translated with first names and surnames. You can have this done by having your birth certificate translated and legalised.

A fun fact:
My mother had 5 first names (when her grandparents were called, which was common in Limburg).
And yes, of course they couldn't put that in the house book. So they chose to shorten the names themselves, so that her last name can no longer be found.

Anyway, I am officially registered in Thailand. However, that does not add anything extra. (also no residence permit)

When buying my condo in Bangkok, they also had to have my parents' names.
No extract or anything
Probably old usage here and in case of confusion they can always verify the buyer like this?

Hahaha they are here just like aunt ES, who is your father, who is your mother?

It doesn't occur to them that they can't do much with that data.
Recently I wanted to have a wound treated in a local hospital after my first name and last name came the question who is? I turned around and went to another hospital.

Even worse, another hospital billed me for 4 days of admission, I never even went to that hospital. In the end I only shared that person's first name, they just started combing the neighborhood for a farang named John.
Totally unnecessary that they need the names of my long deceased parents.
