Interesting.
In a transaction like that, do you just use your run-of-the-mill checkbook like you use to pay for your groceries, or do you have a special checkbook with (physically) larger checks, with room for more numbers?
I use a normal sized checkbook, its the same size as the one I use for day-to day things, but it is a seperate account because of tax and bookeeping issues.
As long as we’re in the post question answered drivel:
Just to add a note to what SandyHook related: a year ago I wrote a check to a car dealer for the full price of the car I was buying and they didn’t even deposit it for a couple of weeks.
From HeyHomie:
The single biggest check I’ve ever personally written was for a bit less than two hondred thousand in the days before us mere mortals had software to print them out. When somebody who’s used to writing checks for fifty-six and 32/100s has to write a check for one hundred ninety-eight thousand eight hundred and sixty-eight and 64/100s they’re liable to be squnching things up towards the end.
Cool! It looks like I’m all set [sub]except that I have to get the money[/sub]. 
Another question.
Can I write the amount-in-words in, say, German, and have it go through an English-speaking bank? If I’m in Germany, can I write the amount in English?
Sunspace scratches his head and is amazed that it never occurred to him that people might write cheques in French in Canada…
If you write a very large check you need to look at your checking account agreement and see how much notice the bank requires to cash the check. In the case of a car dealer where it’s just a matter of moving some electronic blips, it doesn’t matter, but in the case, say of a check to someone interested in cash (for some interesting reason), the bank is only required to keep so much cash on hand, I think 5% of deposits, so they might not be able to cover it without notice.
