Hi Paul and welcome to JA. Ray here to help you tonight.
Sorry you are having to go through all of this.Nothing here has yet to be approved by a judge.
1) In signing this, if I agree to these temporary measures, am I locked or could their lawyer use it against me for the final divorce documents.?
I wouldn't agree to anything without a lawyer.While they say these are temporary all too often they end up being how it is in final decree.So your own lawyer here now before you agree to anything is in your interest.Ask the court for a short continuance of the case so that you can seek to hire a lawyer to protect you here.
Other words, I might file for joint custodial, think I would have a good case, but agreeing to her primary for now, can that hurt me? And second, in general, if this court order reads ok for now, is it ok to sign off on?
This is not good to give this up even on a temporary basis, again too often the other side will then drag it out for awhile and argue this should be made permanent.You can ask for and receive joint custody.I wouldn't agree to anything until your lawyer can negotiate a better joint custody deal.This would be hard to change at final hearing.You want to negotiate here and now.
I appreciate the chance to help you tonight.Thanks again and the best.
