During a relationship we purchase a car for approx $10k, the car was not working at all and had a whole bunch wrong with it that I fixed, sourced parts for and made it road worthy (for the most part)

In 2020, my gf and I were talking about doing up and old car, she wanted an old Porsche and I said that was a difficult and expensive journey how about we look at some easier first projects and suggested a couple of small utes.

We decided on 1 and for favourability we had her do the engagement to see if the buyer was more inclined to sell to her, it worked. The price was fine for what we were looking to do - we went and collected it with a car trailer

During chats around this, I would buy my half through fixing it and parts and during the next 6 months I did that, leaving only that the brakes needed to be bleed before it being completely road worthy

I broke up with her in June last year (I thought she was okay and simply said let me know when you want to sell me the car if you aren’t going to drive it) and she took that very personally and complained to the police. That is all now sorted. Part of that complaint was that I contacted her when she put it up on gumtree. She ignored my request to collect on the situation.

Now I’m trying to go through civil to get my half back as clearly it doubled in price in that 6 months due to my efforts alone. A Vic lawyer said I have a case but I’m in NSW.

The NCAT website doesn’t really describe the best way forward for my situation to claime back that difference, could you let me know where I stand and any advice on moving the situation forward?

Cheers

(On the mobile hopefully it’s not messed up!)
