TSEM9750 - Ownership and income tax: implied trust: constructive trust - evidence
If taxpayers wish to argue constructive trust, you should ask for a full and detailed account of those facts together with all the relevant evidence, as if the claimant were presenting the claim to a court of law. Unless the case is sufficiently strong that you think it would be upheld by the courts, you should reject the claim.
While you may reject a ‘constructive trust’ claim, do not accept a ‘constructive trust’ claim in the income tax context without consulting Trusts Technical.
