In the UK, both partners in a couple can receive the State Pension based on their individual National Insurance contributions. If one partner has a higher National Insurance record, they may receive a larger pension. It's also possible for couples to apply for a 'couple's rate' if one partner is receiving a pension and the other is under State Pension age. Make sure to check your individual entitlements and consider visiting the official gov.uk page for specific details and calculations tailored to your situation.
