"In this case, the Horvaths recorded their interest from Lowery prior to the time the Sabos recorded their interest. Thus, the issue is whether the Sabos are charged with constructive knowledge because of the Horvaths’ prior recordation. Horvath is correct in his assertion that in the usual case a prior recorded deed serves as constructive notice pursuant to AS 34.15.290, and thus precludes a subsequent, recordation from taking precedence. Here, however, the Sabos argue that because Horvath recorded his deed prior to Lowery having obtained patent, they were not given constructive notice by the recording system. They contend that since Horvaths’ recordation was outside the chain of title, the recording should be regarded as a ‘wild deed’. It is an axiom of hornbook law that a purchaser has notice only of recorded instruments that are within his ‘chain of title.’ If a grantor (Lowery) transfers prior to obtaining title, and the grantee (Horvath) records prior to title passing, a second grantee who diligently examines all conveyances under the grantor’s name from the date that the grantor had secured title would not discover the prior conveyance. The rule in most jurisdictions which have adopted a grantor-grantee index system of recording is that a ‘wild deed’ does not serve as constructive notice to a subsequent purchaser who duly records. Alaska’s recording system utilizes a ‘grantor - grantee’ index. Had Sabos searched title under both grantor’s and grantee’s names but limited his search to the chain of title subsequent to patent, he would not be chargeable with discovery of the pre-patent transfer to Horvath."
