Taking someone to trial involves risk. If you lose, you can be responsible for the other side's costs (and even their attorney fees in some situations). Your lawyer should have explained these risks to you. Often, the other side is more interested in making sure you don't appeal than really going after you for costs. You should discuss this with your lawyer, who should tell you your options.
Too much left unsaid. You have to rely upon the advice of your counsel. That is what they are paid to do.
Please be advised that answering your questions does not establish an attorney-client relationship with myself or my firm. We would be more than happy to set up a free consultation if you call us at 407-228-3838 and specifically mention AVVO or email me at firstname.lastname@example.org and put AVVO in the subject line.
