At KGG, our divorce and family law department draws on its four decades of experience to safeguard your interests and advance your goals, including prenuptial, postnuptial, and separation agreements.

Do Prenups Demonstrate a Lack of Faith in the Marriage?
Couples who are planning to get married might shy away from prenuptial agreements on the mistaken belief that a prenup reflects a lack of faith in the strength of their relationship. Every married couple will need to address joint finances and property ownership at some point in their marriage. Considering those issues before the marriage ceremony with a prenup can strengthen the relationship and prevent disagreements as the marriage grows.
If a married couple has not entered into a prenuptial agreement before their marriage, they may enter into a postnuptial agreement to address the same issues.
Paul Goldhamer and his team of prenup lawyers at Kantrowitz, Goldhamer, Graifman, Perlmutter & Carballo, P.C., have advised numerous couples in Bergen and Rockland counties and throughout New York and New Jersey on negotiating and drafting prenuptial and postnuptial agreements that address property and income matters long before they become contentious issues in a marriage relationship. In cases where married couples elect to end their relationship, they have also drafted legal separation agreements that cut through the negative emotions that can poison negotiations in divorce proceedings.
What is a Prenup, and is a Prenup Enforceable in Bergen County & Rockland County?

Both New York and New Jersey are equitable division or equitable distribution states. Married couples that have not formed prenuptial or postnuptial agreements will cede the allocation of their income and property to the vagaries of state law, which, in the event of a marriage dissolution, will look at subjective matters such as each spouse’s physical or mental health, relative standards of living, general economic circumstances, and any other matters that a court deems relevant.
Rather than giving this control to the state, couples who are entering into a marriage relationship can retain a New York and New Jersey prenup & postnuptial agreements lawyer to draft a postnuptial or prenuptial agreement that defines the following matters and other relevant property and income issues:
- Distinguishing the separate property that each spouse brings into the marital relationship from that marital property that might later be divided equally if the relationship ends.
- Addressing expectations for spousal maintenance, particularly if one spouse gives up or postpones career advancements to raise children.
- Providing for children from prior marriages, both during a new marriage relationship and afterwards in the event that new relationship ends.
- Allocating responsibility for debts and liabilities, including student loan debt, that each spouse has incurred prior to the marriage and that the married couple assumes during the marriage.
- Predicting expectations for child support and visitation rights.
New York and New Jersey will generally recognize and enforce prenuptial and postnuptial agreements if they are entered into and executed by both spouses, with full disclosure of all assets and liabilities by each party before signing. A KGG prenup attorney can help couples draft an agreement that meets these standards.
Answers to Common Prenup Agreement Questions
Do New York or New Jersey impose any limitations on prenuptial or postnuptial agreements?
Although spouses can address their expectations for child support and visitation rights in prenup and postnup agreements, they generally cannot predetermine all matters relating to child support and custody. A court will consider the best interests of the child in virtually every instance.
If you have signed a prenup or postnup that includes limitations on support and visitation that you no longer agree with, a KGG prenup lawyer can help you challenge those limitations.
What other basis is there to challenge a prenup or postnup agreement in New York or New Jersey?
A KGG prenup attorney will review the circumstances surrounding the agreement’s formation to determine whether there is a basis to challenge it. This could include, for example, investigating whether each partner in a relationship had his or her own lawyer, if a partner fraudulently concealed assets or pressured the other partner into signing the agreement, and if the agreement’s overall division of income and property is unfair or inequitable.
Are there other options besides divorce proceedings when a married couple is considering ending the relationship?
KGG’s prenup lawyers can also help couples in Bergen and Rockland counties to negotiate and sign legal separation agreements that address many of the same issues in prenup and postnup agreements. Legal separations can be less contentious than a divorce, and they can lay the groundwork to reduce the stress and emotional upheaval that a couple might experience when they elect to end their marriage.
Can a prenup or postnup agreement be modified?
Circumstances can change after a couple is married. For example, one spouse might receive an unexpected inheritance, or both spouses might have a change of heart about property and income after a child is born. New York and New Jersey family law courts will generally treat modifications to prenup and postnup agreements in the same way that courts treat all contract modifications. If the modification is fair and equitable and both parties have agreed to the modification after full and fair disclosure, it will likely be enforced.
A KGG prenup attorney can review a proposed modification to assess its likelihood of enforcement.

KGG Law, and Barry Kantrowitz in particular, set the bar high for what a thorough, practical, strategic, compassionate and smart lawyer can be. Everything about Barry's advice and representation was exemplary and the stress mitigation that resulted was invaluable. On top of that, the ultimate result Barry achieved was beyond what was reasonable to expect and we are forever grateful. Often, people say that you hire a lawyer to prevent a problem. Sometimes, unfortunately, you need an attorney to solve a problem and I could not recommend Barry and his firm any more highly in that regard.Posted on Google

Kate Carballo is a dedicated, passionate, and creative attorney whom I had the pleasure to lecture with at a state trial lawyer's conference. Kate's lecture demonstrated how she uses her innovative and "out-of-the-box thinking" to achieve outstanding results for her injured clients. That Kate is certified by the Supreme Court of New Jersey as a civil trial attorney is a testament to her skills, experience and commitment to excellence.Posted on Google

Was referred to KGG law by a friend and could not have asked for better legal representation. They walked me through every step of the process after my accident and began every call with “ how are you feeling” which was just one example of how much they care about their clients. They handled my case very efficiently, professionally and courteously. My attorney Kate Carballo was a rock star! So clearly experienced, she consistently made me feel at ease with the process. Highly recommendPosted on Google

We had a great experience with the team at KGG Law. While it was a traumatic time for our family, they made it very easy for us and explained all of our options. They even performed due diligence to make sure that after our settlement, there would be no further issues which I think is even more important than the settlement itself. Thank you!
