CG53471 - Debts which are not debts on a security: original creditor
TCGA92/S251 (1)
A debt which is not a debt on a security (and not treated as a debt on a security, see CG53442) will not give rise to any chargeable gain when it is disposed of by the original creditor.
The same treatment applies to a disposal by the personal representative, or legatee, of the original creditor.
