This is an unfortunate situation. You and your contractor should have agreed on a form of dispute resolution before construction began. The agreed upon dispute resolution system should also be included in your contract. Dispute Resolution most often utilizes arbitration or mediation to solve differences that may arise during or after your project. If possible, arbitration or mediation is a cost effective and efficient alternative to the legal system.
Work to resolve this issue as effectively as possible. Putting this off could lead to what is called, "
A Mechanics Lien" against the property.
Understanding your frustration, Possibly try "
meeting in the middle".
Good-Luck.
