In reply to woolsack:
It is possible to pay by Bank Xfer but HMRC suck even more at handling bank payments than they do with cheques as we found out when we got a bunch bounced back to us during a couple week trial period and had to repay them by cheque.
These get sent to our clients every now and again as well, usually it's HMRC having cashed a cheque but not actually ticking that the payment has been received on their side. We just write telling them when the cheque was presented and we don't hear back (assuming they contact the client and tell them it's been paid and to ignore earlier letters).
> c) The solicitor will almost certainly have proof of postage, which is worth quite a lot where HMRC are concerned (I speak from experience here).
We don't keep or get proof of postage. We're sending them a cheque and if they haven't cashed it within a couple weeks we usually reissue the cheque. Most solicitors write to HMRC via the DX system so we don't get PoP.
> d) The solicitor has (AFAIAA, it's certainly the case for share transfers) to send a piece of paper off which comes back with actual real stamps on it, hence the name "stamp duty". It makes sense to attach the cheque to the paper form.
This doesn't make sense. We do the entire thing online except the payment, and for that all we do is write SDLT submission reference on the back of a cheque and chuck it in the post, doesn't need a covering letter. We don't get anything back from them in the post.
