Your decision to pay them the €120 is your call at the end of the day. But if I was in your position I'd still be taking that legal case- the way to win it is all there in black and white in the link I posted- to repeat - there is no legal basis in Ireland for a person to enter into a contract with the use of a sign. The only way a contract can be entered into is verbally or by signature and that point is perfectly clear under Irish law but as yet no one has challenged the clampers on it, once they do then their days are numbered,
And if your solititor charges €200 an hour then I'd advise to find a different one- there are 4,000 unemployed solicitors in Ireland, many of whom would be glad to do it on a no win no fee (especially as the legislation all points towards a winning case). If you had him on a no win no fee then your financial risk is zero. The management company wouldn't be party to the action, only the champers who were the offenders in the first place.
