Thank you for your question
My name is Clare
I shall do my best to help you but I need some further information first
Please confirm that you are not married to each other
What was the agreement made at the time of the purchase?
So what does she think shoudl happen with the rest of the equity?
Are there any children involved?
Has the sale actually completed?
has she asked for a specific figure?
So you are arguing over £3000
You do realise that a court applictaion will take many months to process?
I am sorry but if you take the matter to court you have a chance of her actually receiving a larger amount rather than a smaller amount since there is no Declaration of Trust which means that on the face of it the division of the equity should be a straight 50/50 split.
You will of course be fighting for the arrangement whereby you are each repaid the amount that you originally paid with the balance split between you
There is nothing to be lost by writing a letter - it is to be hoped that it will work.
If not then you can apply for an Order setting out how the proceeds will be divided between you using the Trusts of Land and Appointment of Trustees Act

Please ask if you need further details
That is a possible outcome - provided you prove that it was the agreement that you made between you at the time
