OK, entry of appearance is no big deal because you do not intend to have a lawyer represent you.
The waiver of summons is OK if you have received a copy of your H's petition. But you haven't.
The "consent" part is sort of necessary if his L wants to be able to file the proposed Judgement without you there. The judge or the court doesn't make this stuff up on their own; one of the attornies writes up the order based on the agreement, and the judge just signs it. If there is a dispute, then the judge makes a ruling and then the attorney has to modify the judgement and re-submit it.
That being the case, it is certainly possible that the judge would modify the judgement, based on oral argument from H's L, and that would be legally binding to you.
Bottom line, I wouldn't sign that paper at this point. Again, since you are representing yourself, you can phone or meet with his L directly to iron this out. It seems like it would be best for them to go ahead and file the petition first. That's just bullshit that you haven't seen it.
