Nomination of an Insurance Policy is governed by Section 39 of the Insurance Act, 1938. Considering the section does not have an explicit restriction, the policyholder may nominate his siblings under an insurance policy. However insurers may have different practices so to ensure the principle of insurable interest is complied.
Considering your situation, you can make a partial withdrawal from your Ulip policy to the extent of the amount you are eligible for. This will not only help you manage your expenses but also continue your policy with all the benefits. While this withdrawal will not be taxed, I will recommend that you refer to your policy document for any applicable charges.
