J.R. Hale, a subcontractor, sued Union Pacific Railroad and general contractor K.B. Alexander for unpaid work on subballast materials. The defendants claimed Hale had released its claims and that Hale's own estimation mistake caused the loss. The New Mexico Court of Appeals reversed the dismissal of Hale's contract claim, finding the release documents were too ambiguous to determine whether they covered the disputed subballast work. The case was sent back to trial for a jury to decide what the release actually covered.
Don't sign broad releases without clear language stating exactly what work and claims are being released—ambiguous releases may not protect you or the contractor
Keep detailed documentation of all work performed, change orders, and scope changes; vague estimates can hurt your case if disputes arise
Even if you sign a release, you may still have legal claims if the release language doesn't clearly cover the specific work in dispute
