Yes you are going to be sued. You will have to defend it or you will get a judgement against your name. This will mean she will be able to recover money and it will hurt your credit rating.
But, just because she is starting an action doesn't mean she will win, or even that she has a case to be heard.
You had best seek legal advice.
OK, BUT......This is totally baseless. She contacted me on the 5th December, it is now the 10th December. I've stated many times that I will be refunding her payment if Australia Post does not deliver.
So, how can you start a judgement against someone when there is no money owing AND you've got proof (all the damn messages) that the item has either been refunded OR delivered (paypal records, and/or Australia Post tracking number.
The document I received is a joke. Like Corey said, it is an online document that you pay for without having to go to the Court, or the Sheriff, or even supply evidence of a judgement.
