Actually, that's not true. A contract is a contract, even if its verbal. The question becomes how much is the fight worth to you? Do you have witnesses willing to miss work to come to court to testify? Do you have funds to pay a witness fee if you subpoena witnesses to court? Depositions? The court reporter fee? The attorney fees? The court costs? A process server fee?
And remember - just because you subpoena someone to court doesn't mean you can force them to tell the truth once they're on the stand.
I say this from 20 years experience working for two different attorneys.
I also say this from watching my daughter sell her first horse, the mother of our filly Oops, to a girl who wanted a horse to ride while pregnant that was an easy keeper, sweet horse rather than her own barrel horses.
Nope was sold for 400.00 because my daughter knew her, the agreement was if she wanted to sell her later, we'd buy her back.
Nope was listed on Craigslist in less than 24 hours as a broke-broke kids horse, great for play days and trails, and that she loved her horse, she had had her for years, and just didn't have time for her anymore.
She refused to sell her back to us at a reasonable price, she was seeking a 'kids broke horse' dollar amount out of her: 2500.00
I even offered to pay what she paid, plus a weeks worth of feed and come get her myself.
She flat refused, she made a big deal out of it on a facebook site for local horse owners, her mother called us crack heads, literally called us crackheads... and the insanity only ended when I publicly stated that her daughter intentionally deceived us, it was a lesson learned, and I would not engage anyone in further discussion... Mom and daughter then cloned my daughter's account and proceeded to attack themselves and then reported my daughter. FB quickly figured it out, they were both reprimanded, and only THEN did they figure out my husband had been the probation officer for the girl's dad and mom's husband. (HAD our daughter talked to my husband/her dad about it and told him who these people were, he'd have warned her off them, but she didn't. She did this all on her own.)
Only then did they figure out they'd shot themselves in the foot because they did it all in public and on a forum packed with people we're friends with and do business with. No one wants to do business with them now and they never did get that horse sold.
My advice to my daughter was: If you care one bit about a horse in the future or think you may want the horse back later, do not sell it, and certainly don't sell it to just anyone that has a hard luck story.
