For your next steps (and focussing on your needs) here's some info to consider - may be helpful.
Financial Aspect
To know what a fair split of assets is and to reach a financial settlement divorcing parties need to know what the assets of the marriage are, and what each asset is worth.
Look at a Form E. A long document in which each party sets out their assets, income, and financial needs. You can see in it the assets that are taken into consideration upon divorce and financial settlement, for example property (the former marital home), pensions, stocks and shares etc. It also lists the documents needed that show the value of assets for example CETVs (cash equivalent transfer values of pensions - which can be requested from pension providers).
To find out what some assets are worth an independent expert can be used. Property can be valued by an expert - estate agents, pensions by CETV and / or a pension on divorce expert (PODE) report and so on. It is important to decide what needs a valuation by an independent expert and factor in the costs of these. Pensions can be very valuable – equivalent or more than the value of the former martial home in some cases. Divorcing parties might hold different types of pensions (not like-for-like, so difficult to compare without an expert). Circumstances might be complex for example an age difference or pensions in payment. One party may have stayed at home to look after children.

The income, earning capacity, property, and other financial resource which each of the parties to the marriage has or is likely to have in the foreseeable future is taken into account. As I understand it, first consideration is given to the welfare (while a minor) of any child of the family who has not yet attained the age of eighteen.
The needs of each divorcing party are taken into account and as I understand it 50 / 50 is the starting point – so unequal shares based on circumstances and needs is possible, for example 60 / 40.
Full and frank financial disclosure is required and usually provided when Form E is exchanged. If after Form E there is missing information / evidence Questionnaires may be exchanged to retrieve it and if still missing after that Deficiencies are exchanged. A solicitor’s letter can be sent to retrieve financial information evidence. A Court Order can also be applied for to gain financial information / evidence / valuations that is missing / essential.
