I am being accused of sexual assault by my ex wife

First off, you did the right thing by not talking to the police.  You also did the right thing by not testifying before the grand jury.  Grand juries routinely will meet multiple times on the same case to discuss the "ins and outs" of whether probable cause exists.  Sexual assault, as I'm sure you know, is an INCREDIBLY serious offense and carries huge consequences.  The one thing you need to be worrying about right now is hiring a lawyer.  A criminal defense lawyer, and one that has had success with getting grand jury 'no-bills' on sexual assault cases.  Every sex-assault case I've handled that has been no-billed has been due to the grand jury packet I put together with my client.  Getting your side of the story there is of paramount importance, and there are ways to do it without subjecting yourself to rigorous cross-examination by the district attorneys office.  Find the best criminal defense attorney you can, meet with them, and hire them to get to work immediately on your case.  Time is very important here.  Good luck, hope I helped!   Cordt Akers Criminal Defense Lawyer (713) 426-2244
