Affidavit Of Parental Consent Is There A Form Or Affidavit To Voluntarily Transfer Parental Rights To A Grandparent? If Both Parents Agree.?

Is there a form or affidavit to voluntarily transfer parental rights to a grandparent? If both parents agree.? - affidavit of parental consent

I live in Texas. I am looking for a formula or an affidavit of the transfer of the right of parents to my mother. The father and I consent to the transfer, which we abroad for some time. But we want to be able to redeem the rights of the parents if something happens to my mother or the return. Thank you.
