Invoicing you the $1,800.00 by the condominium association for alleged broken glass on the pool patio is completely different than proving liability and damages against you in small claims court.What you need to do is establish a written record in the event of a small claims court action by your association's complex for the $1,800.00 charge. To do so, you need to first write the association a letter denying any liability for the claims against you for the broken glass, ask for all documents supporting the claims and invoices for the $1,800.00 charge to be provided by a set date.Keep a copy of your letter for future reference and see what the response is. In the interim make a list of all witnesses who could support your position. If the association wants the $1,800.00 from you will require filing a lawsuit. In the meantime, you need not do anything else after you send that letter I suggest.Good luck.
