My response:
Other than obtaining a consultation with an attorney to discuss all of the issues and points, there's really not much you can do at this point until he decides to file an action against you. At that point, then you should obtain the representation of a Family law attorney nearest to where you live. But, it's a good idea to at least talk to an attorney in anticipation of your husband taking you back to court.
It is unlawful for him to merely take it upon himself to write a modification of custody agreement, and have you sign it, and to force you to abide by such a modification, unless a judge says it's okay. He cannot take the court's jurisdiction away by unilaterally changing the current custody orders without a judge signing a modification to the current orders.
Therefore, do not sign anything until such time as you agree to any changes, and a judge is ready to review and approve any such changes.
Good luck to you.
