1. Must apply for PPS number if she doesn't have one.
2. Inheritance tax (if applicable) is paid at Irish rate (I had an overseas beneficiary who spent weeks insisting to me he didn't have to pay tax...yawn.. )
3. Executor should make sure that tax is paid (if applicable) before handing over bequest (or withholding assets to value of tax), as exec can be held liable if tax not paid by due date.
