Can I change my Petition after I have filed

What is the name of your state? Texas
Ok, bear with me on the long drawn out questions but there are lots of details I must include. My husband was imprisoned on 10/17/2001 I purchased a "Do It Yourself Kits" I thought he would sign, so after I prepared my papers I went down and filed my "Original Petition for Divorce" on May 14,2004. This petition states that "the respondent waives the issuance of a citation" (because it was supposed to be agreed) Now that it has been past my 60 days and he won't sign so I now find out that he has to be served a citation and then wait 20 days. Does it matter that the petition says "No service on Resp. is needed"? Am I allowed to change or reword the petition up after I have already filed it through the Dist. Clerk? or does it even matter that it says that and go ahead and have him legally served?

Simply file a 'Petitioners Amended Petition'.

Original Vs. Ammended Petition

Texas
Ok, but my original was automatically printed out for me after I filled in my info. - that is why it said that no service was needed. So how do I know what the "Ammended Petition" is exactly supposed to say - Legally? I don't want to mess up anymore than what I already have by purchasing a DIY divorce but what can you do with no money? Does it even matter that the original states that? I mean if I send it to the Clerk (with the civil process request form) to have the citation prepared, will they still prepare it even though it says that? If there was anyway I could view a sample Original versus an Ammended to compare my papers and that way I could retype my petition myself. Also, so I have to go to the Clerk and refile like I did the orig. do I have to pay that big filing fee? and do I have to wait another 60 days after the ammended is filed before I can ask to finalize the divorce? I know these ?'s may be common sense but I could really use all the help I can get. I desparately want away from this man he has put me through hell, before he was locked up 3 yrs. ago, we do have 2 boys together - the only good out of it. I was very young and dumb to his manipulation - I was still a baby in high school. Again thanks for any help you can give. This is really getting me down.

*** What you are asking from this forum is clearly 'legal services', not advice. As such, the only real advice at this point is to see a qualified attorney in your area.

i am not a attorney, but work in the field. always protect yourself. have the guy served, so he cannot come back later and cause you grief.
