Prior to giving up custody of your children due to finances, please keep in mind that under the TX Family Code, your husband will be required to pay 25% of his income to you in child support, as well as provide insurance for the children. Of course, there is much more involved surrounding the child custody/child support issues, depending on the specific facts of your particular case.
I am a family lawyer in the Dallas area and would be happy to speak to you more in this regard if you would like. My office number is: ###-###-####.
