There isn't enough information to answer your question and without details
of the value of any assets (including pensions) held solely and jointly,
respective incomes, duration of the relationship (marriage+cohabitation
before), ages, numbers of any children, their ages and the average number
of nights they spend with each parent it is only possible to generalise.
The value of any UK and foreign and UK assets held in joint or
sole names are relevant and need to be disclosed. Property abroad can be
offset against assets in the UK.
When a relationship was short
and childless it is common for each party to take what they brought to the
marriage and share any increase in values during the marriage. However,
there is a checklist of factors in s25 Matrimonial Causes Act 1973 that
must be taken into account and the duration of the relationship is only one
factor.
If the needs of both parties, in particular
for children and
housing, can be met from the other assets then inheritances might be
allotted back to the person they were intended for. Alternatively an
inheritance might justify the person who inherited having a larger share of
the matrimonial pot.
If needs can't be met inheritances are
likely to considered a matrimonial asset for sharing.
