... but cashes in MONTHS later all at once WHEN HE GOES TO THE CAGE..... with $4,000 in $1,000 chips he had saved from the earlier trip.

So as I understand it......

1.) Casino fills out Title 31 ..... YES/NO Your answer is NO, since he won them over several sessions, even if over $3K
2.) Casino wants PROOF of ownership of chips......YES/NO Your answer is YES, they can an often do refuse to cash chips without proof of ownership.

Thanks Gene! I am clear now.... The guy in Hawaii is the ONLY guy that cah cash those chips IF he can PROVE that HE won them. Hopefully he won them all at once, like you said triggering his name recorded in the Title 31 book!
