My aunt died abroad and in her will left a percentage to my father who had passed away before she died. In the will she states that in the event of him dying his share was to pas directly to his children. My mother is still alive and does not want any claim on this. There are a number of people inheriting in this will, However it has been said that this would go to her automatically. Q1. Is this correct? Q2. If she disclaims does this go to her children or back into the will for everyone else mentioned in the will Q3. If it does go to my mother is she classed as CAT B or C . The reason I ask this is there is no mention of her in the will just my dad who would have been in CAT B and then us in CAT B. Q4. If I contact the relevant dept in Revenue and they give me answers to the above should I get this in writing as it may contradict what a solicitor might say. Any advice or who would be the best person to speak to on this. Many thanks.
