Outright gifts
To qualify for exemption under , an outright gift has to be to a party to the marriage or civil partnership (). If one or more of the donees is not a party to the marriage or civil partnership, you must apportion the property comprised in the gift between the exempt and non-exempt donees. This applies whether the donees take distinct interests or separate gifts.
Other dispositions
These qualify for exemption only if all the beneficiaries fall within the categories in . The subsection does not permit an apportionment between exempt and non-exempt beneficiaries.
You can regard the disposition as an outright gift unless it creates a settlement. If property is settled by the gift it is an 'other disposition' and falls within . See the separate instructions where the disposition concerned is the termination of an interest in possession in settled property ().
It may be possible to treat a settlement as comprising more than one disposition, for example where different shares of the trust property are settled on different trusts. However, if the taxpayer proposes sub-dividing the separate distinct set of trusts into further separate dispositions, refer to Technical.
