Solicitor fee for calculating Capital Gains

I read from the threads that the solicitor fee for buying and selling the property could be deducted when calculating the capital gains. My flat was bought 7 years ago, could I still deduct the solicitor fee for buying the flat which was 7 years ago? Is there any limitation on the year applicable? Please note that I have never treated /deducted the said buying solicitor fee as expense when calculating/submitting the rental property income return during these years. Do I need to produce the said 7 years ago solicitor fee receipt to support my claim for deducting the capital gains when I sell the flat, please?

Hi,
Yes you can claim the fee from 7 years ago.  If your capital gains submission gets selected for an enquiry then our compliance team might ask for evidence of costs.  
You would then negotiate and liaise with them.
Thank you.
