How does a pension sharing order split a SIPP or a DB pension?
A pension sharing order takes a stated percentage of a pension's transfer value and creates a separate pension for the other party in their own name. It is the cleanest of the three routes because it produces a clean break — neither party depends on the other afterwards.
- The mechanism: a percentage of the cash equivalent transfer value, becoming a pension credit.
- The alternatives: offsetting against other assets, or an attachment order paying part of the income.
- The valuation: the transfer value, which for a defined benefit scheme understates the benefit's worth.
- The timing: the order takes effect from the decree absolute, and implementation takes months.
01 The three routes
A pension sharing order transfers a percentage of one party's pension to the other, who receives it as a pension in their own name — a pension credit — either in the same scheme or transferred elsewhere. It produces a clean break.
Offsetting keeps the pension intact and compensates the other party with a larger share of other assets, usually the house. It is common because it is simple, and it trades a guaranteed inflation-linked income for illiquid property, which is rarely an equal trade.
An attachment order directs part of the pension income to the other party when it comes into payment. It creates a continuing dependency, ends on the death of the member, and is now rarely used.
02 Why the transfer value understates a DB pension
Pension sharing works on the cash equivalent transfer value, and for a defined benefit scheme that figure is the scheme's price for buying out the promise rather than a measure of the benefit's worth to the member. It moves with gilt yields and takes no account of the guarantees being given up.
The consequence is that a 50% share of a CETV does not produce 50% of the income. The receiving party has a pot to invest, bearing investment and longevity risk, while the member keeps an index-linked guaranteed income with a survivor's element.
Where the pension is a significant asset, an actuarial report addressing equality of income rather than equality of capital is the answer, and courts frequently order one. The transfer value question is the same one that arises outside divorce, with more at stake.
Shows: the pension credit produced by a percentage share, and the income it would need to produce to match the benefit given up. Ignores: charges, the receiving party's investment returns, and the guarantees attached to a defined benefit pension.
On the defaults above, the worked example shows £210,000. To match £8,000 a year of index-linked income, the credit would have to produce 3.8% sustainably, before inflation increases.

03 What to check on either side
The member should check whether the scheme charges for implementing a sharing order, whether internal or external transfer is offered, and what the order does to any protection or guaranteed annuity rate attached to the pension.
The receiving party should establish where the pension credit will be held, what it will be invested in, and what charges apply. A credit landing in a default fund nobody chose is a common and avoidable outcome.
Both should check the State Pension, because divorce affects National Insurance records indirectly through changes in employment and Child Benefit claims — and the State Pension itself cannot be shared under the new system.
Source: Getting a divorce
The trap in a divorce settlement is treating a defined benefit pension as though its transfer value is what it is worth. It is not — it is the scheme's buyout price, it moves with gilt yields, and it takes no account of the guarantee or the survivor's pension. A fifty per cent share of the CETV does not give fifty per cent of the income, because one party ends up with a promise and the other with a pot to manage. Where the pension is a serious asset, ask for an actuarial report on equality of income rather than equality of capital.
FAQ
What is a pension sharing order?
An order transferring a stated percentage of one party's pension transfer value to the other, who receives it as a pension in their own name. It produces a clean break, unlike an attachment order.
Is a 50% share an equal split?
Of the capital, yes; of the income, usually not. The transfer value is the scheme's buyout price for a defined benefit promise, and the receiving party ends up bearing investment and longevity risk the member does not.
Can the State Pension be shared?
Not under the new State Pension. Each party's entitlement rests on their own National Insurance record, which is one reason divorce settlements should look at those records as well as at private pensions.
