Lloyd’s requires that all Lloyd’s policies covering business in the US contain a service of suit clause.
The LMA has published LMA5020C and NMA1998B model Service of Suit clauses for use on US policies. These are updates to previous clauses.
LMA5020 and NMA1998 have been withdrawn; NMA1998A, LMA5020A (Lloyd’s security) and LMA5020B (mixed Lloyd’s/non-Lloyd’s security) have now been archived.
For information on the LMA’s archiving and withdrawal process please see: LMA – LMA Archiving and Withdrawal Process for Wordings/Clauses on the LWR.
A flowchart showing usage of these clauses has been published alongside the amendments.

All LMA model clauses are purely illustrative and are published and distributed for the guidance of Lloyd’s managing agents, brokers and other market participants. All contracting parties are free to agree to different conditions/amend the model clauses as they see fit; the LMA does not protect its intellectual property rights over model clauses. It is for underwriters to decide whether or not any contractual language is acceptable on any given risk. Model documents are available on the Lloyd’s Wordings Repository (LWR).
