Bail bondsmen\bounty hunters can do pretty much whatever the want. They don’t have to abide to any rules to recover their fudgitive.
Bondmen are running a service. If they don’t get paid, they will hunt down the person that broke that contract. Because of this contract, assuming you signed it too, you may be contacted to help find the person who skipped out on them. They (probably) won’t physically harm you, but they could get you on aiding a felon if you don’t co-operate. It’s all in the contract.
Yes, you should read the paperwork you signed when “co-signing”. You know have a “contractual arrangement” with the bail bondsman and as such there will not be limits on when, where or how they can contact you.
absolutely.
