Anyone can take someone to the county court if they have a claim from them. You each get to have their say, and a judge decides who is right. This is a good system and surprisingly cheap.
I sometimes think we are however missing something though.
You cannot take court action as a defendant. You cannot force someone in to court as the claimant.
Why would you want to do this? Well, to decide an undecided matter and to remove uncertainty and risk. If someone could take you to court and does not then you have that hanging over you, possibly for 6 years, and it causes stress and uncertainty. If someone is chasing a debt you think you don't owe then getting it settled once and for all is good.
In such cases it would be really good if you could take someone to court as a defendant. To pay the court fees to get them to make their case, or to forfeit any future right to take the case against you. To force their hand. To get a decision now, win or lose, and to know where you stand.
The other thing that is missing is a way to pay for a court decision - sort of like suing yourself - you pay for the courts time to decide something that could happen. i.e. you have a business plan that involves something you are unsure of - pay for the courts time to be devils advocate and decide a case. County courts do not decide legal president as such but would be a good reference for a real case later. It would allow you to understand how the court would consider something and act accordingly.
Just an idea.
