One problem that sometimes comes between divorced parents who have children is that one parent feels that the other is not being fair. They may feel the other parent is trying to sabotage the parenting plan in some way, too.
For example, one parent may continually claim that the child is sick or doesn't want to go to the other parent's home. A parent might claim that the other parent doesn't need their scheduled visitation because they're too busy and simply refuse to meet them to drop off the child.
These disputes may seem minor at first, but they can become serious. Waiting until the disputes you have wear off is not the right plan in most cases. Instead, you need to take the time to discuss the situation with your attorney and decide how to move forward.
If the other parent is violating a child custody court order, you need to document it and take them back to court. If there was no honest or good reason not to follow the schedule, then you have every right to make sure the judge knows about your ex's wrongdoing.
You may be able to avoid court if your ex-spouse is willing to sit down with you and work out the situation. If they're not, then it's best to let your attorneys interact and to head back to court where a judge can help.
The most important thing that a parenting plan should focus on is your child's health and happiness. Resolving a dispute will relieve some tension that could otherwise affect your child's life.
