Rabbi Yehuda HaChassid wrote a famous will.
The only place I was able to find it was on Hebrewbooks.org.
However, it's an old print and an incomplete one at that.
Is there somewhere the complete will?
Try Wikisource - he.wikisource.org - צוואת רבי יהודה החסיד. Can't vouch for its completeness, but it seems to be there.
Hat tip: Google.
