Your State Pension will be based on the old rules if you reached your State Pension age before 6 April 2016.
You’ll have reached State Pension age if you were born before 6 April 1953.
There are two parts to the old State Pension – the basic State Pension and the additional State Pension. They work slightly differently, and you could have built up an entitlement under both the basic State Pension and the additional State Pension or just the basic State Pension.
Your basic State Pension can’t be shared if your marriage or civil partnership ends.
However, divorced couples can use their former spouse or civil partner’s National Insurance contributions to increase their basic State Pension. This won’t reduce the amount of State Pension the other person gets.
If you have an additional State Pension, the court could order that this is shared between you if your marriage or civil partnership ends.
You do lose these rights if you remarry or enter into another civil partnership before you reach your State Pension age.
