Retrospective property valuation for Capital gains tax calculation.

Alberto47

I was added to my parents property deeds as a joint proprietor in April 1999. So a third share. My Dad passed awary November 2025 having been pre deceased by my Mum 10 years earlier. I am now about to sell the property. Will my gains calculation run from the 1999 date when i went onto the deeds or the 2025 date when Dad passed away leaving me as the only survivor and as the sole owner.

Hopefully someone will have something more concrete but I'd imagine you have to do three calculations based on a third of the value each.

First question is who inherited your Mum’s share? Was it your Dad or you?

do you fully understand any claim you may have to private residence relief?
you have not confirmed whether mother's share (*) passed to father upon her death so until he died you owned only 1/3?

your gain is not revalued when your ownership share changes, rather it breaks down into the individual gains relating to each respective ownership share. This seems to comprise
a) gain on original 1/3 share from April 1999 to date of sale
and
b) gain on the 2/3 (*) acquired at date of inheritance from father to date of sale

Who inherits your Dad (and your Mum)’s shares depends what is in their wills, depending on how the property was owned ie tenants in common or joint tenants.

Did you ever live in the home as your principal residence since being a part owner?

Thanks for the responses I will answer in one. Not necessarily in answered order.

Both wills mirrored each other dealt with by my solicitor at the same time as dad hadn't done anything with them. Only Benificiary in the end me.

1. Never lived in the property since added to deeds.
2. Property held in a declaration of trust. Mum, Dad and me Since 1999.
3. Dad again hadn't done anything with the deeds so mum was still on them. Both were removed using deceased joint proprietor removal forms.
4. all documentation carried out when presented to solicitor following dads death In November 2025.

just deciding which retrospective valuation to get as it is time to sell the property.

A deceleration of trust indicates you held the property as tenants in common. Did your mother make a will and if she did who did she leave her share to?

You certainly have a CG liability on the share you were originally gifted. If your mother left you a share of her share in her will you will also have a CGT liability on that share based on the value at the time of her death.

If there was no will or she left it to your father alone then it is likely that your father owed 2/3rd at the time of his death so there should be no CGT liability on that unless it sells for considerliby more than the propate value.

For IHT purposes beneficial rather than legal ownership is what matters so the whole house is going to fall into his estate.

Thanks for the answers

My solicitor has already dealt with the wills and deeds (including IHT.)

I now have a face to face accountants appointment To assist with my CGT liability

please confirm that the mirror will means mum left all to dad and dad left all to mum but the last to die left the lot to their child (you)
if that is correct then as I said
a) gain on original 1/3 share from April 1999 to date of sale
and
b) gain on the 2/3 acquired at date of inheritance from father to date of sale

Pretty much as I see it

Thank you.
