Truscott, TX Divorce Law Firms & Lawyers

You can send the divorce paperwork to your husband's last known address. If that doesn't work, you will need to use local directories (White Pages, Spokeo, etc.) to attempt to find his new address. If that doesn't work, you may ask the court where you filed the divorce paper work for permission to have him served by publication in the news paper. Most courts will allow you to do this if you can show the steps you took to find your husband before making this request. 

Yes, a spouse can sign a power of attorney authorizing someone else to take care of any matters the spouse could personally do, as long as they mentally competent, regardless of whether they are incarcerated or not.  A spouse does not have "a right to everything" if the other spouse is incarcerated.  Spouses often own community property which is subject to their joint control.  A spouse signing a power of attorney does not negate the other spouse's rights with respect to joint management community property.  Spouses often also own property that is one spouse's separate property or is the sole management community property of one spouse.  A power of attorney signed by a spouse can give the attorney-in-fact named in the POA the authority to control the separate property and the sole management community property of the spouse that signed the POA.

At a minimum sue him for what you put in the property. You may also consider suing him for fraud. That may be a stretch, but it is possible. Find a good local attorney to help you.
