A grievance is not a request. And a court can only grant a request.
The pattern
Pages of what has gone wrong, and at the end, nothing precise about what should happen instead.
It's completely understandable. When you've gone unheard for a long time, being heard is the thing you want. But being heard isn't something anyone can order.
Be precise
What arrangement, in what terms, starting when, and why that one is better for the children than what's happening now?
Be proportionate
A specific, well-justified, moderate request is far more persuasive, and far easier to grant, than a sweeping one. Overreach invites refusal on everything.
Try this
Before you write anything else, write the single sentence that says what you want.
Then read your evidence against it, and cut whatever doesn't support that sentence.
It's a brutal edit, and it makes the document much stronger. Everything left in it is now pulling in the same direction, and a reader can see exactly what you're asking them to decide.
What a court can order, and how a request should be framed, varies by jurisdiction. Your lawyer can tell you what's realistic where you live.
General information, not legal advice. Court process differs between countries and regions; check anything that matters to your case with a qualified lawyer where you live.
Chapter 22 of the workbook sets out a structure for your written statement that ends with a precise, proportionate request, and Chapter 14 covers the overreach that weakens it.
