In Oregon, there are no bounty hunters-specific laws.  In State v. Epps, 36 Ore. App. 519, 529 (Or. Ct. App. 1978), the Oregon supreme court abolished the broad common law rights of bounty hunters and bond agents and applied the Uniform Criminal Extradition Act to bounty hunters seeking to take defendants over state lines.

In Oregon, the defendant must not be released from custody unless the defendant files with the clerk of the court in which the magistrate is presiding a release agreement duly executed by the defendant containing the conditions ordered by the releasing magistrate or deposits security in the amount specified by the magistrate[i].

Pursuant to ORS § 131.885, when a person charged with or convicted of any felony within this state breaks prison, escapes, absconds, or flees or hides from justice, the county court or county governing body of the county in which the crime was committed, if the court or governing body deems it necessary, can offer a reward for information leading to the apprehension of such person by the appropriate police authority.  The term bounty hunter is defined as “a private person who is in the business of apprehending persons who have forfeited security or broken the terms of a security release, fled from justice or escaped from confinement[ii].”
