As experienced Long Island Divorce and Family Law attorneys, we are often contacted to help modify a Child Support Agreement or a Child Custody Agreement. Often, the people who approach us are distraught that they are bound by an agreement that does not work for them and their circumstances. This can happen for a number of reasons, including poor representation in their original agreements or a change in circumstances since the original agreements were signed.

On Long Island, which is governed by New York State laws, modifying Child Support or Custody Agreements is, by its nature, very difficult. It’s important to get it right the first time. New York State law has only a few, very strict options to modify these kinds of agreements once they are in place.


Child Support Agreements:

Child Support agreements are governed, by default, by the Child Support Standards Act. This Act is New York Statutory Law and sets forth a step-by-step formula used to determine a parent’s Child Support obligations. However, if the parents can come to an agreement without Court intervention, they are free to agree to obligations that differ from the statutory formula. Once an agreement is in place, there are only a few ways in which to change this agreement.

According to the Child Support Standards Act, an obligation may be changed for three reasons.

#1. If there is a substantial change in circumstances, such as changes in a child’s medical needs, you may petition the Court for a Modification.

#2. If three or more years have passed since the original Order was last entered, modified or adjusted you may petition the Court for a Modification.

#3. If there has been a change in either party’s gross income by 15% or more, you may petition for a Modification. If either of these three conditions are met, you have the right under New York State Law to seek a Modification of your Child Support Obligations.


Child Custody Agreements:

In order to change a Child Custody Agreement, the party seeking the modification must prove to the Court that there has been a substantial change in circumstances warranting a hearing or trial. Such a change may come in the form of a relocation, a change in the child’s medical needs, or the parents may be unable to effectively communicate or cooperate. This threshold question serves to “weed out” the petitions that are being sought for personal revenge or other emotional reasons.

After a change in circumstances has been proven, the Court will then look to the best interest of the child to determine whether a change in custody is prudent. The child’s desires become more prudent as the child gets older.

Some of the factors the Court will look to when determining if a change would be in the child’s best interests are:

  • Maintaining stability for the child
  • Each parent’s relative fitness
  • The desires of the child
  • The parent’s ability to provide for the emotional and intellectual development of the child
  • Each parent’s willingness to foster a healthy relationship with the other parent
  • Whether there has been a finding of abuse or neglect

If the Court determines a change in custody would be within the child’s best interest, such a change will be made.

I went to see Rob for a modification for my child custody agreement to relocate, I can honestly say that working with Rob and Christine has been the best experience. I cannot recommend them enough I only wish I had seen them sooner. They are prompt with communication, and they are honest which I appreciate so much. They do not give you fake promises and they do their best to fight for what you want which they do amazingly well! You can tell they are passionate about what they do and care about their clients. A very important aspect of lawyer client relationship for me is an open line of communication, the anxiety of the unknown always gets the best of us. The fact they were always available whether it be phone call or email to answer any question was extremely comforting and exactly what I needed. I am not well versed with laws and regulation so knowing I had Rob and his partners there when I was unsure or conflicted was extremely needed and greatly appreciated.When it comes to family court it's never easy but having Rob and his partner by my side I felt extremely comfortable and he helped me have realistic expectations. Please TRUST HIM!! If you're looking for a lawyer (at least for my end from child custody/Family Court) don't look any further you will not be disappointed. I hope to never have to use them again but in the event I have to, they are going to be my forever first call.


  • I have known Robert for more than 8 eight years. Robert has represented many of my family and friends. Each and every one has raved about Robert’s professionalism and expertise. He is knowledgable, friendly and truly cares about his clients. I would not hesitate to continue to refer Robert and his firm in the future!
  • I’ve known Robert for most of my life, and feel very fortunate that I have been able to turn to a good friend for various kinds of legal advice. He is very intelligent, straight forward, and professional. Most importantly though, Robert always finds the fastest resolution, and will not waste your time or money. He is NOT in the habit of dragging things through litigation if there is no need for the added expense. I have referred a few of my friends to Robert, and they have all been more than satisfied in their experience with him. Highly recommend!!
