Capital Gains Tax on property when I'm both Transferor and Transferee

My parents and I owned a residential property together. They have recently transferred their share of the property to me. According to the transfer documents (TR1 form) I appear not just as the Transferee but also as a Transferor. Does that mean I also have to report capital gains on the percentage of the property I'm transferring to myself, or given that I haven't stopped owning it that's not needed? Thanks.

Hi,
Your parent's may have a capital gain liability, as they have disposed of their share of the property. You can see guidance here:
HS283 Private Residence Relief (2024)
There is also a Capital Gains Tax calculator here:
Tax when you sell property  
You have acquired 100% of the property in two parts. If you dispose of the property, you would need to obtain the value of the property on acquiring your first share and again when you acquired the remainder. This will allow you to calculate your acquition cost.
Thank you.
