Quoting
Mr. Knowitall
If he has sworn under oath that certain property is premarital, separate property of his wife, it would be more difficult for him to come back a decade later and argue, in effect, "That was just a lie to fool my creditors, and I was the actual owner or owned an equal share." But it is quite possible for property that was once separate to merge into the marital estate by virtue of payment of mortgages and expenses, refinancing, use, retitling, etc.
Have your lawyer review the full facts and present claims, and form a deposition strategy based upon the actual facts.
