Are you interested in setting up a TRUST FUND for your beneficiaries?
Trust funds can contain money market funds, other liquid investments and can be used when alive for asset protection.
They are also great at distribution of funds like life insurance proceeds to beneficiaries when one passes on. 
For example, if you do not want the family to receive full sum assured, say 20 Million at a go, you can have it distributed as Ksh 100,000 per month according to your wishes.
