If you did this on your own, the cost is only going to be a few hundred pounds.
Assuming that Facebook do not oppose the application (which they are unlikely to do)and they simply want the order to formalise it, a solicitor will probably do this for you for a fee of between 500 and £1500.
You will need to serve papers outside the UK jurisdiction (Dublin) and that in itself is quite specialised.
Although there is no legal reason why you cannot do this yourself, it is not really a do-it-yourself job because of the technicalities of the different jurisdiction. If it was in the UK, it would be straightforward but the cross-border element adds a degree of complication to the court application.
Can I clarify anything for you?
