Assumption of risk was once an affirmative defense in Texas tort cases. An "assumption of risk" is similar to a release agreement.An assumption transaction may be accomplished with or without consent of the lender. The transaction involves only a title transfer. In Texas, the assumption of risk doctrine applies when someone willingly engages in activities knowing there are inherent risks involved. The doctrine of assumption of risk is an affirmative defense. It may be available to some defendants in personal injury lawsuits.
