First, the seriousness of this situation cannot be overstated.

In my experience, financial infidelity is more destructive and painful to a marriage than sexual affairs because, it not only involves betrayal, but also criminal activity.

In addition, it is the identity theft no one talks about.  Can you imagine having your identity stolen by the person you sleep in the same bed with??  Why you ask?  Oh yeah, because you signed a marriage license.

Finally, and let me be crystal clear, if your spouse is forging your signature, he/she intends on taking you down with him/her.  It is called fraud, it is a felony and a jail-able offense.  Game over.
