Tax Liability On Inheritance From UK

I have tried to search for posts on this, but have been unable to find an answer.
I have inherited a house and a substantial amount of money from a cousin in UK. Would anybody know:
1. To whom am I liable for tax - Uk Revenue or Irish Revenue?
2. Will the solicitors ( in UK ) handling the estate pay the tax if due to UK Rev. before I get the money, or will I have to see to it myself?
3. Have I to inform the Rev. here if it is due to be paid in Ireland?
4. Is there anyway I can reduce the amount of tax to be paid? I believe it is 40%.
5. Can anyone suggest who I get to look after this for me - a solicitor, an accountant, or a tax consultant?

This may help:

The solicitor should be able to do the whole thing without any need for an accountant.

You will be liable for tax in both the uk and ireland. In the uk the tax is on the estate at 40% over the threshold, the solicitors handling the estate will take it off the top before you get the money. You will also have to pay tax here if you are tax resident here. The tax here is at 20% on amounts over the threshold. One tax can be set off against the other according to tax treaty rules but this is not straightforward. You will need a tax consultant as most solicitors and accountants would not be familiar enough with the tax treaty between the two countries. Most large accountancy firms have dedicated tax departments who should be able to help you.
