He's structuring his withdrawals. Is he doing it on purpose? Was he coached by the landscaper?
The only way I would not file for structuring is if he could show me 3 separate invoices for 9900.00 each. Otherwise he's structuring, even if it at the request of the landscaper. I'd also include the landscaper's info (as much as I have) in the narrative at the least.
I can't herd the cats anymore, so I just set up the electric fences and let them fry when they stray out of bounds.
