In a lot of Montana families, grandparents are not peripheral. They do the after-school pickup, they cover the gap when a shift runs long, they are the reason childcare is affordable at all.

Then the parents separate, and a parenting plan gets written as though the household consists of two adults and some children. It frequently does not survive the first month.

The Two Problems, and They Are Opposite

Grandparents create two entirely different difficulties in a separation, and they need different handling.

The first is practical. A plan that ignores the role grandparents actually play produces a schedule nobody can execute. If Grandma has picked the kids up at 3:15 every day for six years, a plan silent about that has not addressed how the children get home.

The second is emotional. Grandparents are rarely neutral. They love their own child, they have heard one side of the story in considerable detail, and their protective instinct is entirely genuine. That same instinct is one of the most reliable sources of escalation we see, usually from people who believe they are helping.

Parents Decide

Before anything else: including grandparents in the conversation is not giving them decision-making authority. The parents decide.

This distinction gets blurred where a grandparent is providing housing or financial support, and the leverage that creates is real. It still is not authority. A parenting plan shaped by a grandparent's preferences rather than the parents' judgment tends to be unstable, because at some point the parent will assert themselves and the arrangement will be relitigated.

What to Address Explicitly

  • The childcare role. If grandparents provide regular care, name it, so nobody is improvising in week two.
  • Transportation. Who is authorized to collect the children from school, and is the school's list current?
  • Time with grandparents, particularly where it has been a fixture, so it does not silently disappear during one parent's weeks.
  • Holidays. Extended-family gatherings are where most of these plans break, because both sides have traditions.
  • Emergencies. Who is called, and who can authorize what.
  • Commentary in front of the children. Uncomfortable to raise and worth raising anyway.

That last one deserves attention. Children hearing a grandparent characterize a parent are placed in a loyalty conflict they cannot resolve, and they carry it. Most grandparents doing this do not realize the effect.

How the Cooperative Process Handles It

This is a place where the cooperative model does something litigation cannot. A court is deciding between two parents' positions and will not be crafting arrangements around an extended family's logistics.

Working through it directly, parents can build the actual arrangement their family runs on. In some cases that includes a structured conversation with grandparents about expectations, done deliberately rather than through a series of increasingly tense phone calls.

A&M Law serves as a neutral for both parents throughout, guiding the process rather than advocating for either. Our cooperative parenting plan page covers the structure.

When Grandparents Want Their Own Standing

Sometimes the question goes further, and a grandparent wants legally recognized contact or, occasionally, custody. Those are separate matters with their own standards, and they sit outside a parenting agreement between the parents.

Our guides to grandparent visitation rights and a relative seeking custody address those directly.

Worth Doing Properly

A parenting plan that reflects how your family actually operates, including the people who make it operate, is far more likely to hold than one written for a simplified version of it. Call 406-830-3060.
