Extra money from deferring your State Pension
If you decided to defer your State Pension and built up an extra amount, your spouse or civil partner may either claim the extra State Pension or get a lump sum. If you deferred for less than 12 months your spouse or civil partner can only get extra State Pension, not a lump sum. If you deferred for 12 months or more they can choose to get extra State Pension or a lump sum payment. Provided they haven’t remarried or formed a new civil partnership since your death they can get this when they reach State Pension age.
