Hypothetical question

Has anyone dealt with something like this? I'm not sure what my options are.

client won't pay for completed work. I've been dealing with this for about 6 months now and the situation isn't improving.

The contract was signed 19 months ago. I have a copy of the original agreement. The total amount in dispute is approximately $77,000.

What's the typical outcome in situations like this?

Illustrative response

Not a lawyer, but I have direct experience with this.

The #1 mistake I see here is having everything documented. I'd recommend keeping a detailed timeline instead.
