Do I need a lawyer to appeal my Westfield property taxes?
No attorney is required to file at the County Board of Taxation. Many Westfield homeowners successfully appeal on their own using Form A-1 and comparable sales data. PropGap's Evidence Packet ($49) provides the data in the format the Union County Board evaluates. For $149, our Filing Packet includes a pre-filled Form A-1 and a written Chapter 123 argument. Note: for properties with an assessed value above $750,000, consulting a tax attorney or licensed tax agent is worth considering — higher-value cases often involve more complex negotiations and appeals to NJ Tax Court.
