CGT on profit from sale of non-owned property

Several years ago I invested money in a residential property without going on the deeds (more than 4 owners/investors). We had a trust document and now the property has sold I have received my original investment plus % of capital gain. Do I fill in the usual property sale CGT form (within 60 days) or declare it on self-assessment (by Jan 2026) under income from property or sale of asset/cap gain? I had a financial interest but never legally owned the property so questions in the CGT property form don't seem to apply. But is it simplest to just fill it in and pay as if I bought and sold?

Would really appreciate any help with this.

Hi flowertax,
If you have a trust document showing that you are a beneficial owner of the property then yes you will need to declare this as a resdiential property sale and report/pay within 60 days.
Thank you.
