State Farm’s 998 offer was valid and enforceable to shift costs in this case.  The signature block contained a space for signature by the attorney for the HOA, which was sufficient to identify the party in the signature line for acceptance.  Also, the 998 offer’s requirement of signature on a settlement agreement releasing all claims ” arising from, relating or in any way pertaining to the subject matter of the Action” did not create a disabling ambiguity regarding the claims to be released.  Read in context and as a whole the settlement agreement was clearly limited to claims in the underlying lawsuit.
