Limitation period reduction for estate duty narrows survivorship look-back to one year; new exemptions for pensions and gifts. Amendments shorten multiple two-year look-back periods to one year across provisions governing dispositions, settlements, trusts and property passing on death, add provisos excluding houses taken by close relatives from being deemed to pass on donor or settlor's death solely due to the donor's residence unless a right of residence is reserved or secured, insert an exemption for certain pensions and annuities payable to widows or dependants from specified approved funds or schemes, and add a clause treating gifts to close relatives beyond five years before death with conditions tied to gift-tax chargeability.
