For capital gains tax purposes a beneficiary normally becomes
absolutely entitled to assets as against the trustees on attaining
age 18 or earlier marrying. However it could be earlier if the
trustees exercise their statutory power of advancement (Section 32
Trustee Act 1925. There is a definition of
‘advancement’ in the glossary.)
If the trustees retain the assets subsequently it will be in
a bare capacity (TSEM1030).
There is advice on ‘absolute entitlement’ for
capital gains tax purposes at CG37000 onwards.
