Common questions
Frequently Asked
4
When may a promisee enforce a subrogation right against a promisor after paying an intended beneficiary?+
A promisee who satisfies an intended beneficiary's claim from its own assets acquires a right of reimbursement from the promisor. That right may be enforced directly or, once the beneficiary's claim is fully satisfied, by subrogation to the beneficiary's claim against the promisor and any related judgment or security.
Does a transferor of mortgaged property retain subrogation rights when the transferee assumes the debt?+
When mortgaged real estate is transferred with assumption of liability, the transferor is a secondary obligor and the transferee a principal obligor. The transferor may obtain relief against the transferee and the mortgaged property by subrogation if the transferee defaults or impairs the transferor's expectation of performance.
What limits the timing of subrogation rights under letter-of-credit rules?+
An applicant's right of subrogation against a beneficiary or nominated person does not arise until the issuer honors the letter of credit or otherwise pays. Rights of a nominated person likewise arise only after payment or value is given.
How does the collateral source rule interact with an insurer's subrogation claim?+
Payments from a plaintiff's own insurance are ignored when calculating the defendant's tort liability under the collateral source rule. Any reimbursement occurs afterward through the insurer's contractual or equitable subrogation rights against the recovery, not by reducing the judgment against the tortfeasor.
