TR1 consideration property sale

Do I put the actual purchase price on the TR1 Land registry Form when selling to family member - purchase price is less than mortgage valuation but purchase price has remained same. Solicitor is using box 3 on panel 8 to show a part gift equity -/ purchase price whereas I thought purchase price box 1 should be used then declare CGT under the 60 days ruling.

Hi
You need to contact the land registry office for that.
Thankyou.
