MWPA is the Married Women Property Act of 1874 that entails that if a married man, including a divorcee or a widower, buys life insurance with the MWP addendum, the insurance benefits upon maturity or death are the sole property of the nominated beneficiaries (wife, or of his wife and children) and no one else. Even the policyholder does not have any right over these benefits.
The entire sum is treated as separate fund from the policyholder's estate and hence, these benefits cannot be used for repayment of debt or loan or form part of joint family property, in case of the untimely death of the policyholder.
