Thanks for confirming average cost would apply to disposal. So in the circumstances of W re-acquiring 50% interest in house from H's estate so W then had entire interest and therafter gifting 50% to children as PET there would be a deemed capital gain calculated on W's average base cost not on H's probate value and your original answer a) saying otherwise (i.e deemed gain based only on probate value at death) needs to be corrected in these circumstances.

Thanks for confirming that there is no such a restriction in UK - so in the hypothetical circumstances of H having been diagnosed with cancer and having been given a few months to live: if W had gifted her 50% interest in second home to H; H in his (revised if necessary) will devised his 100% interest in second home to her; she gifts 50% interest after his death to children as PET; then the result given in your original answer a) would be correct. Yes? [and that also would have removed extra wrinkle of related property IHTA 1984 s161 creating possible difference in valuation of circa 10% on H's 50% interest for IHT and CGT as he would have owned entire house on his death not just a 50% interest ]
