Google adsense blog guide you what to do if your checks expired after 6 months.
If you're holding onto to a check and it expires, your account will be placed on hold and you'll need to re-select a form of payment to resume payments the next time you've crossed the US $100 threshold. For many of you, you may consider trying EFT, Western Union, or local currency checks if they're available in your country. If you don't yet see your preferred payment option for your country yet, please know we're working hard to add additional forms of payment in the future.
Google will not let go your money anywhere if its not credited to your bank. It will go right back to your adsense account.
