Aegon will launch an online trust analyser tool this month to help advisers identify which of their client's mortgage and family protection policies should be placed under trust.
The tool will analyse the client's situation, showing the advantages and disadvantages of a trust for their individual circumstances.
The provider warned that a range of problems and delays can arise when claiming on a life insurance policy which has not been written in trust.
And with as few as 6% of protection policies placed under trust, it highlighted that many families may be unaware they are leaving themselves vulnerable to these obstacles.
"If a policy hasn't been written under trust, payment to the intended beneficiaries may be delayed, payment may not go to the intended beneficiaries, unnecessary inheritance tax may be payable and the policy proceeds may not be protected from creditors," the provider said.
"We believe many more protection policies should be written in trust and we're launching this tool to help advisers ensure their clients are properly protected."
