Steve or someone else will correct me if necessary but it seems that :
- all the fees involved before the escritura are paid by the seller (what you did it seems).
- the impuesto al sellado is divided 50/50
- the honorarios paid to the escribano usually are paid by the buyer, unless otherwise stated before. This percentage usually turns around 1.5 to 2%. I've noticed some sources stating 3% while some others say 2% should be the maximum.
- all the fees involved after the escritura are to be paid by the buyer

My personal experience (just for two rentals) with escribanos has been poor :
- First time, renting a house in provincia, the escribano did not charge the sellados (they are mandatory outside of capital). No big deal since it's risky for the owner and the escribano asked for a low amount.
- Second time, 6 months ago, again renting a house in the provincia, the owners wanted to do everything in the most legal way again. I said fine. The escribano asked for a 3% commission on the totality of the contract. I thought it was a bit excessive so I asked the owners if that included the sellados (0.5% of the contract if I recall). They said yes.
The day we went to sign, the owner asked again the escribano about the sellados, and the escribano answered "nobody pays the sellados" (the fine is quite heavy, and if I, as the one renting was to stop paying the rent, and if we were to go to Court, the owners would need to pay a heavy fine). We gave anyway the 3%, the escribano gave to each of us a kind of invoice titled "factura provisoria" with just a signature. This escribano is a crook, very friendly & charming -like all the crooks-.
Morality : beware and call the collegio de escribanos
