With regard to your first question about petitioning the court for a reduction in child support and/or spousal support, unless you have experienced a dramatic drop in income, I do not think you are going to be very successful in your efforts, but in any case , you probably should wait until the first year has passed.
With regard to your second question regarding the presence and welfare of the children, you have every right to know that they are being taken care of properly and to know their whereabouts, especially when they are left in the presence of a stranger. If you had proper legal counsel when you got divorced, your attorney should have made sure that such issues were adressed in your Separation Agreement or in the Judgment of Divorce. There should be a provision in the Separation Agreement providing for access to the children by telephone when they are not by you and with regard to their presence and the nature of supervisory care that they are receiving when the resident parent is not with them.
I strongly suggest that you consider mediating these matters with your ex-wife rather than going into court. Mediation will be cheaper and quicker and less traumatic. If you are living in the New York City metropolitan area , please call me at 212-370-1660 to arrange for a meeting for us discuss mediation.
