A person can claim MEA on a contribution made towards somebody else's expenditure that qualifies for MEA if:
Treat the person making the contribution as if the contribution
were expenditure on an asset similar to the one towards which the
contribution was made and that asset were in use for the purposes
of the contributor's trade at all material times. This means that
the contribution can qualify for MEA.
If the contributor's trade is transferred WDAs after the
transfer are made to the person to whom the trade is transferred.
If part of the trade is transferred make WDAs to the transferee to
the extent that they are attributable to the part transferred.
