Date I got share of the property

I inherited a property from 2 parents, the first Probate for half the property was in 2022 and the second probate for second parent when the remainder of the property was inherited was 2023. Can you tell me which probate date I need to enter on the capital gains tax self assessment form. I spoke to someone at hmrc and they said the first date but my brother has spoken to a tax consultant who said the second date. You cannot enter 2 dates. Can someone please confirm which date we need to enter for the date I got my share of the property

Hi Gill Fuller,
It will be the first date that you use as this is when you fist acquired the property (or the share of the property).
Thank you.
