Bound to maintain

“Children are bound to maintain their parents.”

That is not a proverb. It is Section 1563 of the Thai Civil and Commercial Code, and it says what it says. One sentence, no conditions, no means test, no expiry.

Most Thais have never read it and every single one of us knows it.

Because the statute isn’t the mechanism. กตัญญู — katanyu — is the mechanism, and it does the enforcement work that no court in this country has ever seriously been asked to do.

What it actually costs

Here is the part nobody puts a number on, and it turns out somebody has.

Around 60% of older Thais receive financial support from an adult child. Among those who do, the median is ฿22,250 a year.

That’s ฿1,854 a month.

Set the state old age allowance next to it — article 38, ฿600 a month at the lowest band.

฿2,454 a month. About ฿80 a day.

That is what a Thai old age runs on: the median transfer from a child, plus the state allowance, together, for everything. Against a ฿50 plate of street food from article 13, it is roughly a plate and a half a day and nothing else.

And note the split. Roughly three-quarters of that income is a moral obligation. One quarter is public policy.

The bit that should worry everybody

There’s a finding in the research that reads, at first, like good news.

Since the old age allowance became universal, studies report children declining in importance as a primary income source and the allowance rising.

Read that again with the numbers attached.

The allowance is ฿600 a month. The median child transfer is ฿1,854. For the allowance to overtake children as somebody’s main income, the child’s transfer has to have fallen below ฿600 a month.

So this isn’t the state stepping up. It’s the family stepping back, past a bar set almost at the floor — and being recorded, in the aggregate, as an improvement.

I’d want a demographer to push back on me here, and the effect is partly about regularity rather than size: ฿600 arriving reliably on a date beats a larger sum arriving when a child can manage it. But the direction is real and the direction is the problem.

Why the arithmetic is about to break

Katanyu is stated as an obligation on a child. The need, however, is attached to a parent. That difference is fine when there are four children and catastrophic when there is one.

Thailand’s 60-plus population is now above 21% — more than 14 million people. The worker-to-older-person ratio has fallen from above four to around three. Projections put the over-60s at a quarter to 28% within the next decade.

And article 09’s fertility rate is 1.18.

So the obligation stays constant per child, while the number of children available to share it collapses. A duty that four siblings once split is arriving intact on one person. The norm hasn’t weakened at all. It’s simply being asked to do four times the work with the same materials.

That’s what a cultural safety net looks like when the demography moves underneath it. Nobody stops believing in it. It just stops adding up.

Where it lives: next door

Over 70% of older Thais live with, or immediately next to, a child.

That’s the delivery infrastructure. Katanyu is not primarily a bank transfer — it’s a granddaughter in the same house, a meal cooked, a hospital trip driven, a house shared. The money is the visible portion of a much larger transfer that never shows up in any statistic.

Which is exactly why article 65 matters here. Primacy separates the family geographically, and katanyu doesn’t relocate. The obligation survives the move to Bangkok; the co-residence doesn’t. What’s left is the money — the thinnest and most measurable part of a duty that used to be delivered mostly in person.

Article 37’s remittance economy is what katanyu looks like once you take the shared house away from it.

The uncomfortable part

I’m going to say the thing that’s difficult to say as a Thai person, because it’s true.

Katanyu is a genuine good. I’m not going to pretend otherwise. A society where the elderly are not warehoused, where the obligation runs both ways across a lifetime, where nobody has to ask — that is better than a great many alternatives and I would not trade it.

And it has also been load-bearing policy for eighty years.

A country whose families reliably absorb old age is a country that can defer building a pension. Not through any decision anyone made — nobody sat down and chose ฿600 a month as adequate. It’s ฿600 because it never had to be more. The family was already doing it, so the gap never presented itself as a gap.

This is article 61’s argument again, one layer deeper. There, private companies filled in where the state didn’t build. Here it’s private families, and the filling-in is so old and so total that it has never once been described as infrastructure.

Article 57 said the parallel economy grew in the gaps the formal system left. Katanyu is the oldest of those gaps and the largest, and it is the only one held together by nothing but shame and love.

What foreigners get wrong

Because I know who’s searching this.

It is not a transaction and treating it as one will end badly. The money is an expression of the thing, not the thing. Partners who negotiate the amount as if it were a subscription have misunderstood what is being asked, and everybody in the family will notice.

It is not a scam. The single most common accusation in expat forums is that a Thai partner sending money home is being exploited. Sometimes families do behave badly, as families everywhere do. But the default case is a legal duty, a universal norm and a woman doing exactly what her brothers are also doing.

The amounts are usually smaller than you fear. The median is ฿1,854 a month. That is the middle of the actual distribution, not the number in the forum post.

And you cannot opt your partner out of it. Section 1563 doesn’t have a clause about marrying a foreigner.

Common misconceptions

“It’s just tradition.” It is also statute — Section 1563 of the Civil and Commercial Code.

“Thai families always support their elderly.” About 60% of older people receive support from a child. Which means around 40% don’t.

“The state pension covers the basics.” ฿600 a month is roughly ฿20 a day against a ฿50 plate of food. It covers approximately nothing.

“Modern Thais have abandoned it.” The norm is intact. The demography isn’t. Those look identical from the outside and they are not the same problem.

“Sending money home means the family is greedy.” The median is ฿1,854 a month, it is a legal obligation, and every sibling is doing it.
