Fathers’ Rights

Fathers’ Rights, for me, is a matter of treating all cases the same, regardless of gender. Father’s Rights is not prejudging a case based on gender, it is applying the law to the facts of each and every case.

If your lawyer starts out trying to negotiate a settlement for you without filing in court, great! But if it is taking too long, file in court so that you have some controls applied by the court.

Child Support

The law is the law, cold and cruel without much basis in reality. In most cases, it calculates to what it calculates. In some cases, it is on a case by case basis, as to deviating from the guidelines.

Having once been the client before he became a lawyer, he understands the need to try seek resolution to reduce conflict for your benefit and your children’s benefit, rather than feed your emotions that only serves to escalate the litigation and legal fees. Never litigate emotions!

If your lawyer is too aggressive too often, nothing will settle and everything will litigate. If your lawyer is not aggressive enough, you may give up too much. A proper balance is necessary. Mr. Greenfield seeks that balance and understands that to minimize litigation and conflict will not only keep your legal fees to a minimum but more importantly, minimizes the emotional and psychological scars caused by the divorce process.  Thus, healing will hopefully be reached sooner for your sake, and the sake of your children.

But if litigation cannot be avoided, he is more than up to the task and is ready, willing and able to fight hard for you!

He represents both men and women and believes that the term Fathers’ Rights only means that every case should be decided on its individual merits of the facts as applied to the law without regard to gender.

I have known Mace for more years than I can count, and have witnessed his professional growth from law clerk to establishing his own firm. A few years ago I hired Mace to represent me in a very difficult and complicated divorce. He did his best to keep my legal costs at a minimum while representing me with his full attention. I can honestly say that I can thank Mace for allowing me to retain and enjoy my full pension today.

If honesty and integrity are important to you, then I highly recommend Mace Greenfield. Sadly, I have experienced less than ethical practices by other attorneys on Long Island, and therefore feel qualified to proclaim that I have been represented by the best lawyer on Long Island.


No hassle of dealing with a firm – what you see is what you get. Very knowledgable in the area of Family Law. Had I went to him first instead of my original scam artist firm, my case would have been resolved much quicker. Would definitely use again, and with my psychotic ex, will probably have to.


I used Mace for a prenup and an annulment. He made the process very easy and at times fun. He finished everything very quickly, and never tried to drag it out for more money. I was shocked it went through so quick.


Mace has helped me in my divorce………..twice
He is the man!


What I liked the most about Mace was that he listened to what my needs were and he didn’t try to bully me. Also, he is a very fair person and although he looks to protect his own client, he is not the type of attorney that will try to make your divorce go on any longer than it has to just to get more from you or your ex to be.


I want to say from the bottom of my heart thank you for helping me through this struggle. You’re truly an awesome lawyer and I appreciate your hard work. You’re truly good at what you do. Thank you. Merry Christmas.
