Can a contractor sue me if I sue them?

While not always the case, be prepared for the contractor to file a counter claim if you ultimately decide to sue them.  We see this most often in cases of alleged deficiencies.  The homeowner sues for the costs to fix and/or finish the job and the contractor counter sues for the amount left owing on the contract.  It is then left to the judge to determine who is owed how much and why.  Only after such a determination can the claim or counterclaim be properly disposed of.
