Your question does not make sense. An agreed order can usually be modified when it pertains to children or child support, and that includes visitation. If you have an attorney, you should ask your attorney these questions. You or your attorney can go to court to address the matter. No one will represent you behind your back or without your permission.
yes, an agreed order can and may be modified.
there are appellate cases that say that the visits may not be left up to the child.
we have no idea if you can go after child support. maybe yes, maybe no. consult with your lawyer about that. you say you have had one for years.
your lawyer should handle your case. if another lawyer does, he or she should have knowledge of the case.
go see your lawyer.
There appear to be multiple questions here.
Generally, a motion may be filed to clarify an Order, where the Order incorporates a parenting agreement and the language of the Order (or agreement) contains errors or inconsistencies. (When the error is in the drafting, this is called a "scrivener's error"). Occasionally, awkward language in an agreement causes unintended consequences in the enforcement of an Order which may only be addressed by a corrected Order.
The other question has to do with "maintenance" and child support. If the maintenance is termed "unallocated" this generally includes an amount of child support and is ordered to allow the payor of support a tax break. So long as a child is in its minority, both parents have an obligation to support the child, and this may be expressed by a "guidelines child support order" to be paid by the noncustodial parent--(the parent who does not have primary care of the child). Sometimes, under a joint parenting agreement, the parent argues that his direct payment of the child's expenses and the increased time spent with the child takes the place of the guidelines child support amount that would normally be ordered.
Finally, the question of the attorney sending someone else--presumably from his office--to cover the case should be taken up with that attorney. (Often, there is an express clause in the retainer contract signed at the beginning of representation that allows the attorney to designate another attorney from his firm to substitute for him in court).
