Get an attorney that represents you and not your Irish wife.
It's pretty clear, to me at least, that they are not on your side.
Ask the OCI for a list of private attorneys in Ireland that have handled Hague cases.
If they refuse to provide you with such a list (they wouldn't give one to me but I know they've given them to other parents in these forums) you may try getting such a list from the British Central Authority who routinely deals with Ireland.
You can also ask the NCMEC for a similar list of attorneys. They told me they weren't allowed to give me one either (though I believe, in their case, they are following the rules that State gives them) but I also know of another LBP (mother) who got one of my attorneys contact details in a list from the NCMEC.
Even if you decide not to hire a private attorney many some are willing to provide a free consultation where you can get some good advice from people who know the local laws and, hopefully, know how the Convention works in their country. Also, almost any good attorney is willing to work out a payment plan. Oftentimes it is the crap attorneys who want their payment in full up front.
There are always some attorneys willing to handle these cases pro-bono, but most of them only work for mothers. Actually, now that I think about it, I can't think of any father getting an attorney to take his case pro-bono.. ever, but there's a first time for everything and many of us are out there breaking new ground and blazing new trails in trying to bring our children home.
Some important questions you should be able to answer:
Where did your solicitor come from? Does she work for the Central Authority, or is she just some public defender assigned to the local family court that has been assigned your case? Has she ever handled a Hague case? Who appointed her?
Have you tried contacting the Irish Central Authority directly yourself? If not, you should, and discuss with them the concerns and problems you are having with your representation and see what they suggest. Perhaps they can assign someone different.
