My father is a contractor, and was agreed to do a job on a nearby house to build a ramp. He has a contract with the person who hired him; however he still hasn’t been paid the full amount both parties agreed on ($20,000). What type of lawyer can I search for and is there any advice on how to proceed? I assumed construction lawyer (hence why I’m on your website), but if I’m misunderstanding — kindly advise me on where I should be looking instead. Please let me know, thank you.
