From what I read on the original post, why would he even put them down on his list of assets.

I mean, it appears from the orig. post that she hasn't asked for them.

It could easily and reasonably be assumed that they are not his property, that they are property of either the airline or employer, or that he 'forgot'. I'm sure that in 99% of the divorces, airline miles are not that big of a deal.

If she asks for them, then the valuation problem will come in.

Finally, the more documentation he can get regarding value from the airline, or from an authoritative source.. yes even Randy.. will help support his cause once he needs to value the miles.

I would start by going to the airline(s) with the balance and seeing what I could get from them. If you don't get what you like, call again, isn't that the airline way..

Also, do they value these in their financial statements? If so that is a possible source.
What about using ebay to see what people are selling them for. Take all of these, or the lowest one. If that doesn't cut it, have a formula prepared that will give you the lowest value. Have a note from your employer, or if they do have a policy that the miles belong to the company, print it. If they are non transferable, print that rule. Print/Support anything you can that goes to his advantage.

Remember too, if she has any miles whatsoever, those can be used to offset his balance. If she has any outstanding credits from the airlines, use those to offset. Use whatever you can, that normally wouldn't be considered in the asset pool to offset his miles.

But why bring them up in the first place. I know one of you lawyer types will say b/c you have too.. again my arguement is that a reasonable person would not think of this as an asset. Not all people are like us here on FT where it is the most precious asset we own LOL
