Allowable deductions for Capital Gains Tax

Compulsory share is an institution of inheritance law in Poland which aims to protect testator’s closest family members against being completely deprived of their share in the inheritance. I was named by the deceased in their last will and testament as testamentary successor and consequently I have paid out monetary entitlement to the children of the testator, would that be considered allowable deduction for Capital Gains Tax on sale of a foreign property?

Hi,
No as the expenditure must have been incurred wholly and exclusively for the purposes of the acquisition or disposal.
See guidance at CG15250 - Expenditure: incidental costs of acquisition and disposal
Thank you.
