Anybody self represented in court?

[Thefutureismyaim]

Has anybody self represented for the finances?
stbx has legal representation. I can’t afford legal representation as I quite like being able to feed my kids and I am not getting any child maintenance despite having the kids 100%.
stbx has already spent £5k on legal fees and we have only got to the first appointment stage. I did look into legal representation but the costs were estimated to be £20k upwards if it goes all the way to final hearing. It will go all the way to final hearing because stbx thinks I am only entitled to a share of the house and not a share of any other matrimonial assets because he was the breadwinner. It was a long and abusive marriage.
Am I going to be seriously disadvantaged by not having legal representation?
is it difficult to represent oneself in court when the other party is represented?

If you are happy to give approx location one if us might be able to suggest one we have used? Mine is south based, and was really good.

How did this work out for you, court is the next step for us and I’m terrified

I am doing it myself with the help of ChatGPT which I’m finding very useful. I’m doing it myself mainly because I think solicitors are way to expensive and I can’t really afford it
