More than one in 10 divorcees (11%) have either delayed or forgotten to remove their ex-partner from their wills and financial products, according to a new report.

A similar number (10%) of divorcees have forgotten to remove their former spouse as the beneficiary of their life insurance policy.

The failure means that in the event of a claim their ex could receive the payout.

Only 7% of divorcees have discussed life insurance beneficiaries as part of their separation, according to the research from L&G.

Only 27% had cancelled a joint life insurance policy they had when they were married.

These errors are leaving many divorcees vulnerable to financial errors which could have long-term consequences. However, only 7% of people will consult a financial adviser as part of their divorce, according to the research.

James Shattock, managing director of UK protection at L&G, said that without taking financial advice divorce can be more costly than it needs to be.

He said: “Divorce is always difficult but, without advice, it can be a costly too. It’s really important for anyone going through a separation to be fully aware of the financial implications of divorce and to ensure they review other important elements, like their wills and financial products like life insurance, to ensure beneficiary information is updated.

“Advisers can play a key role in supporting clients during a separation, helping them to put a plan in place for the costs associated with a divorce, any shared debts and, potentially, making sure a Clean Break Order is in place.”

Once separated, most divorcees did not prioritise protection insurance with only 4% of people taking out a critical illness policy and just 3% taking out income protection.
