This is being run by the courts service, as you can see from the actual web address you get to when you access the www.smallclaims.ie web address.
I’ve never submitted a small claim, so I don’t know how good the site is. I went part way through the process online and found it fairly intuitive.
One thing I did notice though was that there wasn’t much blurb to let people know (apart from the €2000 limit) under what circumstances they may lodge a small claim. There isn’t either really a clear description of what the process is when lodging a small claim if you haven’t done this before. These may be detailed within the application process, but I would have thought it’d be handier up front.
