Mr Burgess said where SMSF clients do have children in their fund, its important they’re aware that once these children turn 18 they will need to appoint an enduring power of attorney.

"While it probably won’t be at the top of their to do list, [we need] to get that person’s enduring power of attorney or indeed their entire estate planning arrangements sorted out,” explained Mr Burgess.

“Once a child has turned 18 and maybe they have an event, the parents are no longer able to act. The parents, probably quite rightly, because it's been the right answer for 18 years in a row, have assumed that they continue to have authority and they don't need any extra documentation to create that authority. It's simply not the case, though.”

Mr Burgess explained that the moment an individual turns 18, assuming that they are otherwise capable, they must takes steps to appoint who they want as their legal authority and the only way to do that is through an enduring power of attorney.

“It may not be the most amazing birthday gift to be receiving as an 18 year old but if they’re the member of an SMSF, you’ve got a material risk I’d say as the adviser if you're not effectively mandating that that documentation gets put in place basically immediately,” he warned.

“There’s an increasing number of horror stories relating to this issue. One example from the not-too-distant past was where an 18-year-old went to the running of the bulls in Spain and got knocked over and spent months in a hospital there because of a stoush between the Australian embassy and the Spanish embassy people about whether there was any legal authority to the parents because an enduring power of attorney had not been appointed.”
