State Pension is normally claimed by the individual and is based mainly on their National Insurance record, so it cannot usually be transferred to another family member. If they cannot manage their claim, you may be able to act as an appointee, subject to approval by the Department for Work and Pensions (DWP). If the person has died, their State Pension normally stops, although a spouse or civil partner may be able to inherit certain payments or claim bereavement support, depending on the circumstances. Check the official GOV.UK guidance or contact the Pension Service for the relevant rules.
