It is not legally necessary for co-parents to have the same sorts of house rules and regulations, even if they both have physical and legal custody of their children.
For big decisions like where a child attends school or what type of medical care they receive, legal custody rights are important. If both parents have these rights, then they need to work together and cooperate to make these decisions.
But for more minor things like rules regarding cellphones and screen time, bedtime or curfew, parents can have very different rules from one household to the next. A child may know that they have to be in bed at 9 o’clock at one parent’s house, while they are allowed to stay up as late as they want at the other parent’s house.
Similar rules can be helpful
That being said, the above is just addressing the legal distinction. You are not obligated to have the same rules as your ex. But, if the two of you want to create the most stability and consistency for your children, it can help to have similar rules in place.
After all, this helps children know what to expect. That alone can give them a greater sense of stability after a divorce. It also reduces conflicts, as children may prefer one set of rules and argue with the parent who does not allow the same sorts of activities or who has a stricter ruleset at their home.
Ultimately, it depends on the unique details of your coparenting situation. If the two of you are on good terms and can set up similar rules, that’s fine. But if you disagree with some of your ex’s rules, do not feel that you have to follow them when the child is under your care unless your parenting agreement requires you to do so.
If you have any questions about your legal or physical child custody rights, it can be helpful to work with an experienced attorney. Co-parenting is rarely a straightforward journey, and seeking legal guidance when necessary can help.
