Additional costs - Land Registry and Assenting

In order to sell the house of our late parents, my siblings and I have had to get the property registered with Land Registry (it had never been registered previously) and also to have the house "assented" to us. Are both of these necessary expenditures considered as "additional costs" which can be taken into account when reporting Capital Gains Tax? If so, do they fall into the additional costs in the Sale/Disposal Details section(?) or in the Purchase/Acquisition Details section? Thank you.

Hi,
Please have a look at the guidance at CG15250 - Expenditure: incidental costs of acquisition and disposal for guidance on those costs that are allowable expenditures.
Thank you.
