When couples divorce, pensions are often one of the most misunderstood aspects of the assets available for division. Unlike cash sitting in a bank account or a property that can easily be valued, pensions tend to be financially complex, and that make them difficult to compare directly against other assets.
One method of dealing with pensions on divorce is pension offsetting. This is often viewed as the most straightforward solution because it avoids the need for future financial ties between former spouses. However, calculating pension offsetting fairly is rarely straightforward.
What is pension offsetting?
Pension offsetting happens when the value of one spouse’s pension is balanced against another asset, so that instead of splitting the pension itself, the other spouse receives a greater share of non-pension assets.
For example, one party might keep their pension intact while the other receives a larger share of the equity in the family home, savings, investments, or another valuable asset. This option is often chosen because it allows both parties to move forward financially independent of each other. Unlike a pension sharing order, which transfers part of the pension into the other spouse’s name, offsetting avoids ongoing involvement with pension administrators and can feel cleaner emotionally and practically.
It is especially attractive where one party wants to retain pension certainty for retirement while the other prioritises securing housing for children after separation.
What assets are commonly used to offset a pension?
The most often-used asset used to offset pension value is the family home. A common scenario involves one spouse retaining their pension while the other receives a larger share of the equity in the property. This is particularly common where children will remain living with one parent and housing stability is a priority.
Savings and cash deposits are also frequently used because they are easy to value and immediately accessible. Investment portfolios, including ISAs and shares, may also be used. However, these are slightly more complicated because market values fluctuate and there may be tax implications when sold.
Business interests can sometimes be offset against pension value, particularly where one spouse owns a company or partnership share. That said, this can be difficult because business valuations are rarely precise and often depend on assumptions about future performance.
Less typical assets may include overseas property, trust interests, inheritance expectations, or valuable personal possessions such as artwork or collections. These are generally more difficult to value objectively and often require specialist involvement.
Why is valuing a pension so complicated?
Offsetting appears to rely on simple maths — compare the pension’s value with another asset and divide fairly. However, in reality, valuation is where the greatest difficulty lies. Pensions are usually valued using the Cash Equivalent Transfer Value (CETV). This is the figure provided by the pension provider and represents the theoretical cash value of transferring the pension elsewhere.
The problem is that CETV does not always reflect the true benefit of the pension, especially for defined benefit (final salary) schemes.
A CETV may significantly undervalue or overvalue what the pension is actually worth in retirement. For example, a final salary pension offering guaranteed inflation-linked income for life could have a relatively modest CETV compared to its real long-term benefit.
By contrast, defined contribution pensions are generally easier to assess because the fund value broadly reflects the available retirement pot.
A further complication is that pension value is not directly comparable to cash or property equity. A £300,000 pension is not the same as £300,000 in a bank account. Pension funds are usually inaccessible until retirement age, may carry tax implications on withdrawal, and provide future rather than immediate benefits. This means offsetting calculations often require applying discounts or adjustments to reflect these matters.
How age and timing affect the calculation
The ages of both spouses can significantly affect pension offsetting calculations. If both parties are approaching retirement, the pension’s immediate relevance is greater and precise valuation becomes more important. But where retirement is decades away, future uncertainties around investment performance, inflation, and legislative changes can complicate assumptions.
The length of the marriage is another important factor. If much of the pension was accumulated during the marriage, it is usually more likely to be treated as a matrimonial asset available for sharing. But if substantial pension rights were built up before the relationship began, arguments may arise about whether part of the pension should be excluded from division as non-matrimonial property.
Courts consider fairness rather than rigid formulas, and the presence of children can also affect offsetting decisions. Housing needs often take priority over pension equality, particularly where one parent will provide the children’s primary home.
Final salary pensions: The most difficult cases
Final salary pensions often create the greatest difficulty in offsetting cases. Unlike defined contribution schemes, these pensions promise a set income for life, usually linked to salary and years of service. Many also include valuable benefits such as survivor pensions and inflation protection.
The CETV for these schemes can be misleadingly low compared to the income security they provide. This creates a risk of unfair offsetting if one spouse keeps a highly valuable final salary pension while the other receives property equity based only on the CETV.
A pensions expert can calculate the true comparative value of the pension, estimate what equivalent defined contribution fund would be required to replicate the same retirement income, and advise whether any adjustment is necessary. This evidence can substantially alter settlement negotiations.
For example, a pension with a CETV of £400,000 might actually provide benefits equivalent to a much larger retirement fund. Without expert input, offsetting could significantly disadvantage one spouse.
Can one party insist on pension sharing instead?
A spouse cannot simply demand pension sharing because they dislike offsetting. The court’s role is to determine overall fairness, and it has discretion to choose the most appropriate method.
Possible outcomes include:
- Pension offsetting
- Pension sharing orders
- Pension attachment orders (less common)
- A combination of methods
The court will examine the wider financial picture, including housing needs, income disparity, retirement provisions, and practicality.
If offsetting would leave one spouse inadequately provided for in retirement, a judge may favour pension sharing even if the other spouse would prefer to keep the pension untouched.
