Commission Sale For A Sailboat Question About Splitting A Commission Sale.?

Question about splitting a commission sale.? - commission sale for a sailboat

My husband works for a company to termites and the regional director and branch manager approached him and asked him to sell a job.

Originally a different supplier, two months ago, the advantage was that it's a game that was in the lead and not sell. He wrote the word in the file offset, if you give it up and thrown.
The administration has said that he knew that not to sell the others, and it was like a new track for my husband
He sold it today and now the other half wants to sell and the manager told my husband he has to divide.

That is unfair, and if that was the original intention that it should have said. I had to visit the house and hiding place and everything is not so new.

What you can do so from halF with a sale of 3 bosses, as he said it was yours?
