Ummmm. If I was acting for other spouse I'd be sceptical about the whole thing. Actually, if I was the Judge, I'd be saying ah! ah!. Don't be moving your assets around.
All of these cases are different. But if the Divorce is going to happen quickly -what is separation time span? - why not do all things together? The other spouse can then only come back looking for maintenance and if a figure is agreed or ordered by the Court, its not really going to get varied that much in the future.
As regards stamp duty, given that two of the offspring are ftb's, I would seriously question the concept of them getting into an investment property situation ( yes it probably will be duty payable at investors rates), particularly where a Divorce is involved.
Any other views?
