SDSINC is correct, you can't push .ES as we know a "push" to be, I bought a .es name last mo, asked sedo if I could gain control of it at another registrar, I was told to open an acct at NIC.es, and was I in for a rough ride ! nic.es has a form which needs to be submitted electronically (looks like a will), sedo said to fax it to them after I completed my part and they'd have to do the submission, I was also told to produce a copy of my passport page (or driver's lic if you're in the US) there are IDs the form asks for but if you don't live in Spain you can't have that, the NIC.ES site is complicated, I actually needed Sedo to give me a link to open an acct (could not find it and I'm Spanish!)
And if you had wanted to have left control of the name w/the same registrar it was the same thing, so why not do a whole transfer? then the NIC.ES form kept rejecting my email add !? 3 times. I then opted to have NIC.ES have control the name, not a new or the current registrar, then it worked ?! I have a real problem giving an auction site and even NIC.ES all info disclosed in a passport/driver's lic, FOR THE EQUIVALENT OF A PUSH ?! the info was sent to NIC.ES electronically, that made me real uncomfortable, I knew you couldn't have privacy w/a .ES name but now if even my email add changes there's a "process" for that w/NIC.ES, so considering .DE, .co.uk, .NL are all ahead of .ES (.es does have > 1 M already) it is way too demanding as a process, I'll tread carefully w/.ES in aftermarket, hand-regging a .ES name is much simpler
