CCJ - how do i find out who from?

Allkid

I got informed that i had a CCJ that was filed back in 2019 against me. 
I was unaware of this, i've not taken out any loans but can guess where it came from. although it was paid off.

what i want to know is, the name of company that the CCJ issues by, has it been marked paid.

i am confused with who would be the best website to check up with, Equifax, Experian, Clearscore, check my file?
i do not want to subscribe to theses sites, and not sure if the free one will give me the information i want.
any suggestion?
thanks

Contact the court who issued the CCJ, you will need to provide the court claim reference number.

Credit reports are free from:
Credit karma

Clearscore
MSE credit club

There's 3 main CRAs, a smaller 4th one which is little used. Financial services don't always report to all 3 (or 4) CRAs, however the CCJ should be on all of them.
