Winning a judgment or arbitral award is not the same as being paid. Judgment enforcement financing provides capital specifically to fund the process of collection: asset tracing across jurisdictions, local counsel in the country where a defendant's assets are located, and the often years-long process of enforcing a foreign judgment or arbitral award against a resistant debtor.
This category is attractive to funders in one specific sense: liability is already resolved. There is no merits risk left in the case, the open question is purely collectability, which is a narrower, more analyzable problem than predicting how a trial will go. Global funders such as Omni Bridgeway, which built much of its franchise around enforcement and recovery, treat this as a distinct specialism from pre-judgment case funding.
Typical diligence for enforcement financing focuses heavily on where the defendant's assets actually sit, which jurisdictions will recognize and enforce the underlying judgment or award, and how sophisticated the defendant has been about shielding assets, questions that are quite different from the liability and damages analysis used for pre-judgment funding.
