I understand when I die, my son will get a tax allowance of £325 going up to £500 as he will inherit my home. When my partner died, the solicitors doubled up on the tax allowance for probate as his previously deceased wife left under the £325 allowance. My ex-husband died recently and I wonder whether my son could use the £325 allowance from my ex husband's estate which was not needed. I seem to be getting different answers from different solicitors so thank you for any help. I don't see why I should again be taxed on money I have already paid tax on. Thank you.
