I am completely confused here and I think that your boyfriend should not pay anything until he speaks with an attorney.  From the way that you have phrased the question it appears that he is paying her off in some way.  But it is unclear if this money is a proper distribution of marital assets or if it is a bribe - for lack of a better word - to get her to give him the divorce.  What is clear is that you need an attorney to draft up a settlement agreement that is iron clad.  Please do not agree to anything unless an attorney reviews it and advises you on your rights in the matter.  Good luck to you.
