In England and Wales (I don’t know about Scotland or Northern Ireland), Inheritance is NOT automatically a marital asset and is usually excluded from the marital pot during divorce unless:
- It has been combined with the marital pot / mixed into the family finances e.g. used as a deposit on the family home etc.
- There is not enough money in the family pot to go around and provide for everyone’s NEEDS (not wants) adequately without* *it being included i.e. someone will be left homeless / on the street without it
From the information you’ve given, it seems the inheritance has been kept separate to the family finances and there is enough money in the marital pot to house you adequately (with no dependents you only need a 1 bed) so since neither option applies to you, you need to forget about the inheritance as you’re not entitled to it.
With regard to his pension, you absolutely are entitled to a share of it so if you really want to keep the house, you could use it as leverage to negotiate a bigger share of the house by saying he can have more of the pension etc.
The first step is get the house valued (average of 3 valuations) and both your pensions valued as well; even though yours is small, it will still have to be included. Once you know what you’re working with in terms of figures, you can go from there BUT keep in mind that a* pension £ is worth less *than an equity / cash £ therefore it won’t be a straight forward £ to £ trade off between the two.
Beyond that, other factors that can influence a settlement include earnings, ages, savings, debts, other assets (such as cars or significant jewellery), health etc.
As always, definitely get legal advice though.
