If you paid cash for the apartment (ie no Irish mortgage), and it was a second hand apartment in County Dublin ( or any other county after oct 05) you may only have had to sign the contracts which the solicitor could have posted to you in England, the solicitor may have signed these on your behalf but this would be quite unusual particularly if the solicitor did not know you personally. Although it is usual for purchasers to sign the transfer deed this is not always necessary depending on the transaction and registration can take place without it being signed by the purchaser.
