Inherited a share in a property on 2 separate dates and selling to 2 different buyers

A client inherited a quarter share in a property in 2010 and a further quarter in 2015. If our client sells her 2 quarter shares to 2 different buyers, would we need to report the gain separately to HMRC - submit 2 reports?

Hi Rhys C,
As long as both disposals take place on the same date, then they can be combined into one single Capital Gains Tax calculation and the gain declared together.
If the disposals take place on different dates, then they need to be declared separately.
Thank you.
