This is an example of a costs sharing agreement, which could serve as a useful starting point when drafting such an agreement. It will, however, need to be tailored to your particular circumstances and needs. It covers, among other matters, how the costs will be apportioned between the claimants and what the liability of a claimant will be if they join or leave the litigation after the agreement is signed.

This costs sharing agreement must be read in conjunction with the integrated drafting notes, which explain why certain clauses have been drafted the way that they have and why certain clauses are optional.
