You have four jobs?
It is 50% for everything that is in joint names - 100% for everything else!
It is generally about what extra you did - but if you brought more capital than your ex did then you can say so!
You are seeking the sale of the matrimonial home and an unequal division in your favour
You can do that - it will do no harm!
Yes that is a good action plan
No it is the Form E you need not an E1
If you are sending it to your ex direct then only send two to the court - on for them to keep and one for them to seal and return.
Do not use the word Compensatory
Just make sure that you work it into your contribution to the family
You are most welcome
