Legal Question in Wills and Trusts in Texas

His mother is his natural guardian and as such has the responsibility to raise him..etc..and if your husband and you set up a trust..that should be administered according to its terms and as to the home..you have a life estate so the house cannot be sold by force.....but she has a right to do something..depending on how all has been arranged

If you're setting up a trust fund for the son with money he left to you (i.e. your own money), then you should talk to the mother and work out an arrangement. If you're acting in the child's best interest, she will hopefully reciprocate and treat you fairly. You can use this opportunity to set up a healthy relationship with her and the child (if that's what you want, I'm not real clear from your posting.) As has been noted, you have a life estate in the house, so you have the right to occupy as long as you like.

As a widow you should have a life estate in his portion of his house. Please contact an attorney so that all interests can be allocated to prevent confusion, expense, and ill will among the parties.
