Answer
In a divorce, the court will always try to split assets including pensions in the fairest way possible. So pensions are split dependent on the circumstances of the couple. The court will try to achieve an equal division where possible but a 50/50 split may not be fair when you consider all the factors.
When deciding how a pension should be split, the court takes into account all the points listed in the Matrimonial Causes Act 1973. This includes the needs of any children, the financial responsibilities and expectations of each party, future earning potential, the length of the marriage, how much each person contributed to the marriage and the other assets they have.
After this, the court may find that a 60/40 or 70/30 split is more suitable based on the situation for instance.
