Child Custody

Emotions may have brought the two of you into divorce or family court, but the emotions must be checked at the door. The case must proceed based on a combination of facts and law.

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.

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 regardless of gender. In other words, it is a striving for equal rights within the courts.

Visitation it really parenting time, no matter what it is called. If you and the other parent were still together, you would be supervising the child, driving him or her places, and providing funds. It is no different now. Be a parent, not a visitor!

Having once been the client before he became a lawyer...

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.
