Hi P Du,
UK Capital Gains Tax rules allow for the transfer of assets between husband and wife and civil partners to be free of Capital Gains Tax.
You inherited your 1/3 of the property when parent 2 died.
For capital gains purposes, you would obtain the market value of the property at the time you inherited it and using the exchange rate at that time, convert the value to pounds sterling.
You can then work out 1/3, to get your inherited value.
Using the official exchange rate in use at the time of disposal, convert the disposal value and disposal costs into pounds sterling and work out 1/3, to get the disposal value and costs.
Subtract the inherited value and disposal costs from the disposal value to work out the gain.
As long as all of the figures are in pounds sterling, you can use the calculator at to work out the gain.
Tax when you sell your home
The gain should be reported in a Self Assessment Tax Return.
There are 3 official exchange rates at:

You can choose which of them to use.
Thank you.
