If you keep house, and put it in all three names, there will be no stamp duty but, depending on the value ( it is market value) you may have an Inheritance Tax liability. ( Capital Acquisitions Tax)
If you do a Deed of Family Arrangement and e.g. only put house in on or two names ( one/two sell/gift to other/s) you may have stamp duty and CAT liabilities.
If you decide to sell house, the estate may have a Capital Gains Tax liability on any difference between date of death value and sale value.
Three separate taxes are at play. Your solicitor should be able to guide you towards tax advice.
As a practising solicitor, I will advise generally on tax issues but generally advise clients to seek specific advices themselves.
