Questionaire/Statement of issues difference

Hello! I am representing myself against an ex partner. We were not married but have an 8yo child together and she is looking to get more money, a bigger house from me etc. We have our 1st appointment soon. What is the difference between the Questionnaire and Statement of Issues that I should fill out? All help much appreciated!
Also, her solicitor will only exchange Form G, H etc after I have sent my mine (tomorrow)....is this usual?..I feel that it is unfair because I am self representing (I would rather court costs saved go to my child).
Thank you

Is this a Children Act case??
The process and proofs needed may not be the same as those for financial settlement on divorce.
I imagine though that the question of need and the means you both have to meet them will be important.

The questionnaire is designed to make sure there is full disclosure of finances and that needs have been appropriately stated. It is aimed at ensuring the judge has all the relevant evidence available to them.

The statement of issues is a list of things you don't agree on that you need the court to help you with. This may be anything from the value of a property (an order can be madde for a joint valuation) to the parties' incomes and earning capacities, their strict housing needs and whether/when they can be independent of any support the court may think is appropriate. The objective is to try to narrow the issues by agreement if possible and leave as few as possible for the judge to consider.
