Family law expert for divorce asset calculator

Hi, I need to work alongside an experienced family solicitor to give me the raw information I need to create:

- A high-level list of assets/items that are considered when adding up a couple's assets for division after divorce
- A basic plus/minus way of totalling these up in order to get a rough total asset pot
- A list of the factors/caveats that need to accompany this (e.g. if inheritance is treated differently, or personal debts are treated differently, of if the marriage is short, etc)
- Anything else I should be considering re adding up assets

There are some similar calculators online, so we can use these as a basis, I just want to be sure that this calculator isnt missing anything obvious or has obvious errors.

Thanks

Andy
