If you have a Retirement Income Stream, you can choose to nominate a reversionary beneficiary who will receive your regular pension payments after your death.
If your beneficiary is older than 67 and receives your super or Income Stream as a lump sum on your death, they may not be able to re-deposit the money into the super system.
By nominating them as your reversionary beneficiary, they will continue to receive an ongoing pension, rather than having to worry about what to do with a lump sum of money, especially at such a stressful time.
