How are savings, shares, and other financial assets shared on divorce?

The starting point for any division of assets is 50:50, as set out in section 25 of the Matrimonial Causes Act 1973. Broadly speaking, matrimonial assets are those built up during the course of the marriage up to the date of separation, and are treated differently to non-matrimonial  or pre-martial assets. These are considered to be assets either previously owned before the relationship began or acquired by one party, such as an inheritance or gift.
