What is the current status of my claim?

The best way to check the status of your MtGox claim, regardless of whether it was filed through Kraken or not, is to log in to claims.mtgox.com. While claims can be linked to Kraken accounts, all of the details of the claims themselves are still stored on MtGox Trustee servers - not on Kraken. There will be chances closer to the time of payouts to re-link any claims to a Kraken account if there are any problems.
