CGT: inherited partial property and recently sold in Hong Kong

Hi I moved to the UK in 2022 and my late mother's flat in Hong Kong was sold in March 2024 and the transaction completed in April 2024. Please find below my questions: 1. My mother was a non-UK resident. The flat that was sold had been her main residence, in which I had lived for over 20 years before I got married. The sale of the property was shared by my siblings and me equally. Is there capital gain tax or any other kind of tax that I need to report to? 2. If CGT applies in my case, which financial year does it fall to? We received a deposit in March 2024 at the time when a temporary property sale contract was signed. The entire property sale transaction was completed in mid April 2024. 3. If CGT applies in my case, how is it valued to calculate the CGT? Thank you.
