Financial Settlements
Does adultery affect a divorce financial settlement? (2026)
Adultery stopped being a ground for divorce in England and Wales on 6 April 2022, and it has almost no effect on how money is divided. The court divides assets by reference to needs, sharing and the section 25 factors, not by apportioning blame for why the marriage ended. Conduct is only taken into account under section 25(2)(g) of the Matrimonial Causes Act 1973 where it would be inequitable to disregard it, a high bar met by serious physical harm, reckless dissipation of assets and non-disclosure rather than by infidelity. The one route where an affair touches the numbers is money: significant sums spent on a new partner can sometimes be added back notionally to the spender's share, and a new partner who contributes to household costs affects a spousal maintenance needs assessment. Child maintenance is unaffected entirely, because the Child Maintenance Service applies a formula to gross weekly income with no conduct element.
