Clean Break, Short Marriage and Pre-Marriage Asset

Take the following situation. Husband brings to marriage house and savings and pension. Wife brings nothing. No kids.
According to the calculator, for every year of the marriage she is gaining 10% of this wealth for the pot, and the husband is losing out. After a certain time period, she appears to be given more than 50% of this pot. Can this be right? I can understand that this may be the case if the couple have kids, but why would she be entitled to a greater share, having brought nothing to the marriage ?

Any ideas ?

Forget the calculator.

Its usually 50/50 and a Clean Break when there are no children.

Exceptions are where there was violence in the marriage and disabilities of the parties involved.

The calculator is good at crunching numbers but doesn't take account of individual circumstances.

In a short, childless marriage (normally less than 5 years) it is unlikely that a 50/50 division of assets will be ordered particularly if one spouse brought substantially more assets to the marriage. Normally assets acquired prior to the marriage will be retained, or returned to the spouse who originally had them, and assets accrued during the marriage will be divided 50/50 when the parties divorce.
