Involuntary transfers are not subject to the federal anti assignment statutes.  The subrogation of an insurer to an insured’s claim against the United States as a result of paying an insured’s claim is an involuntary transfer and therefore does not violate the federal anti assignment statutes.  The subrogation of a surety upon payment of a performance or payment bond that the surety issued to a government contractor is also considered an involuntary transfer and not subject to the federal anti assignment statutes.
