. I received the petition that included a waiver of service. I was told that would keep us from having to have a court hearing.
Told by who?
Who prepared the petition? Her? Lawyer?
There are any number of reasons that the need for a hearing might come at some future date.
Question is the petition I received the same as what I would receive if I didn't sign and was served?
It should be.
Big concern is the petition I received was the "intro" of what would be added after I signed
I don't understand what you mean by that.
What is the petition asking for?
no longer get any notification of changes from what I received in the original petition.
Any subsequent pleadings and filing have to be sent to you when they are filed.
We have no children, no real assets to be concerned about.
Did you get something like this?
Original Petition for Divorce [Divorce Set B] (texaslawhelp.org)
Likely omitting any reference to children.
See Page 8, paragraphs 11A and 11B.
Is the proposed division of assets and debts satisfactory to you? Something you have discussed with your wife and agree on?
You can check the court docket and see if the petition has been filed and then get a copy from the court and compare it to what you were sent.
You can also talk to your wife about filing a joint petition, though I don't know if that's available in Texas.
