if you refer to courts.ie then you will find in the small claims section avery clear and comprehensive answers to most of these questions. Briefly to each question (where you have a question mark)
-No, you do not assume correctly. No "official" (small claims registrar )makes any judgement - He/she tries through reading various correspondence between parties and ,sometimes, a meeting with both to reach an agreement. Failing agreement the matter then goes to open court -district court.
(Some registrars can take several months passing claims,responses, counter-reponses etc to and fro -and then deciding to hold a meeting to discuss matters.)
If the matter does go to court...
- Yes there is a risk of claimant paying costs if claimant's case is regarded as having no merit.
-Yes claimant can claim costs.
(However, few small claims do go to court and the costs are usually minor -but every case is different. Prior to court there are no costs)
- Yes, courts can -and often do- decide that there is partial blame on side of claimant if even claimant "wins".Obviously this may mean reduction in amount of claim.
- Yes, any district court decision can be appealed. Then you are heading for big expenditure.
I don't know answer to last question as regards records and whether district court decisions are a basis for case law.I'd imagine not.
From first contact with your local small claims court it can take two years before final court judgement,especially in Dublin.
My advice - go down to the small claims people and chat to someone. (-after reading websites such as courts.ie, citizens advice etc. Forms can be downloaded.)
