Who should pay, or not pay, who in this letter written in business Japanese?


In my JLPT textbook, I have a short letter in business Japanese, which is
where I'm definitely weakest.

The letter is from `山口商事` to `森山工業`, and here it is as it appears in the book.
Sorry for all my markings. I hope it's readable:

Here is what I think is the relevant part of the letter:

>
> 当社は、上記上田物産株式会社に対し、金100万円の債権を所有しておりますが、同社はその後倒産し、貴社に対しても売掛金の支払いを催促した様子は見られません。
>
> つきましては、上記債務を当社にお支払いいただきたく、ご通知いたします。

The question about the letter is `この文書は何を要求しているか。` And the given answer is,
`山口商事が森山工業に100万円支払うこと`. My understanding from that answer is that the topic of
the letter is the Yamaguchi company paying a million yen to the Moriyama
construction company.

What I can't figure out, though, is if the Yamaguchi company intends to pay
that money. The part where it says `売掛金の支払いを催促した様子は見られません` makes me think that
they're saying they don't think they have to pay. They "can't see any
indication of their obligation to pay", or something like that.

However, the `上記債務を当社にお支払いいただきたく、ご通知いたします` part makes me think that maybe they
do intend to pay. Actually, it's very confusing to me, because I thought
`いただく` meant to receive, so do they expect to _receive_ payment of some kind?

Where am I getting tangled up in all this formal business language, and can
anyone help me untangle it?




I'm not really sure where the question is, so I'll just explain what I see in
the letter.

Moriyama is writing to Yamaguchi. So Yamaguchi is the 貴社.

Yamaguchi owed Ueda the 100万円 and didn't pay for over 6 months. Ueda went out
of business. Moriyama is now the owner of the debt post bankruptcy. The いただく
phrase is indicating that Moriyama should receive the money.

The letter is written by KAWAKAMI Tarou from the [総務]{そうむ} group at Moriyama
stating the above fact (i.e. requesting payment).
