My Ex-Wife Is Trying to Gain Custody of Our Children after Our Divorce Decree

By Beverly Bird

Divorce decrees are not necessarily forever, especially regarding custody. Even when parents enter into a custody arrangement by consent and the terms are included in the decree, they always have the right to change their minds as to what they agreed. However, unless both parents consent to the change, modification of the decree requires court approval. Court approval hinges entirely on what is in the best interests of the children and can be difficult to achieve.

Changed Circumstances

If the underlying reason behind your ex’s willingness to relinquish custody has changed, she might want to revoke her decision to step aside as the custodial parent. She may have had a mental health issue or a substance abuse problem that she has now successfully defeated. However, this is generally not a sufficient reason for a court to overturn an existing custody arrangement. Your ex would not only have to prove that circumstances have changed and she's now a good parent, but she would simultaneously have to prove that something has occurred to make you a bad parent. Unless your own life has changed so dramatically that your home is no longer safe for your children, this might be very difficult for her to accomplish.

Legal Procedure

Your ex must file a post-judgment or post-decree motion with the court, advising that she wants to change the custody terms of your decree. She must usually include a written affidavit or certification with the motion, explaining why she wants the change. This will not automatically change your decree. In most jurisdictions, a judge will review her paperwork and schedule a hearing. Because changing custody is a far more serious issue than other post-judgment issues, such as recalculating child support, most courts will not make such a decision at the motion hearing. In all likelihood, the judge will use the occasion of the motion hearing to order a plenary hearing. A plenary hearing is the same as a divorce trial, but it occurs after the divorce is final. Both you and your ex can call witnesses, testify on your own behalf and offer documented evidence to the judge.

Best Interests of the Children

After reviewing all evidence and listening to testimony during a plenary hearing, the judge will base his decision on the best interests of your children, not on the validity of your ex’s desire to change custody. Courts usually do not believe it is in children’s best interests to suddenly uproot them from the home of their primary caretaker. Judges generally give a lot of weight to existing custody orders and won’t radically change them unless something very significant has taken place to make the old arrangement unworkable. The benefits of changing custody must be greater than the stress such a change would cause your children. Many state courts will also consider the children’s wishes, especially if they want their living arrangement to remain as-is. Courts give more weight to children’s preferences when they’re older.


Because you already have an existing custody order in the form of your divorce decree, your best defense is that nothing has changed since your ex gave up custody, so there’s no reason to uproot your children. However, a plenary hearing is usually a complex and lengthy legal procedure, so you might want to hire an attorney to help you make this case. If you don’t believe you ex’s circumstances have changed since she ceded custody, an attorney can help you gather evidence to prove that. He can present it to the court through document exhibits and witness testimony.

Dating During the Temporary Custody Phase of a Divorce in Oklahoma

Oklahoma's divorce statutes don't include a specific prohibition about dating. They don't say that if you go out for dinner with someone, your chances for gaining custody are nil -- but they don't say it's OK, either. Typically, the issue depends on the opinion of the judge who hears your case and how he feels about dating before a divorce is final -- particularly if you have children. Some common-sense considerations apply, however.

How to Behave in Custody Battles

The end of a marriage is difficult, but the idea of losing custody of your children is terrifying. A judge's only concern in deciding custody is your child's best interest. Parent behavior during a custody battle can influence the judge as he decides which residential placement meets that criteria. Knowing a judge's criteria in terms of your behavior can better help you demonstrate that your child's best interest lies with you.

Divorce & Changes in Circumstance in Massachusetts

Ideally, if a significant change occurs in your life, it will happen while you are in mid-divorce, so your eventual decree can adequately address it. This isn't usually the case, and Massachusetts allows spouses to modify the terms of their decrees after divorce to accommodate changes. However, unless you and your spouse agree to a modification by consent, Massachusetts judges require “substantial and material” changes in circumstance before they’ll issue a modification order. “Substantial” means the change must be big; “material” means it must directly relate to the provision you want to change.
