Isti,
The UFDA appears to be more prevalent in complex civil cases. The UFDA requires that the party requesting the deposition hire a local attorney (in your state) to get permission to subpoena you to the deposition (in your area).
If you're the one who slept with the wife, it's doubtful H will have the funds to pay for a foreign deposition. H and W during a divorce are usually suffocating on normal divorce bills and living expenses for two houses where there once was one home, nevermind the trauma to the kids.
If one party signed over mucho commumity property to you to divert it from the other, you may, indeed, get a subpoena.
