A written split feels like the end of the argument. Usually it is only the start of the next one. Before anyone initials a page, check what it actually commits, who holds it, and when it gets looked at again.
Local option: New Plan Care gives families in the St. Louis area in-home help so a parent can stay home: companionship, help with bathing and dressing, meals, and overnight care. Call (314) 405-0887.
Check every line for an owner
Read each row out loud. If a task has no name beside it, it is a wish, not a share. Look for three things on every line: the task (the Saturday grocery run is a task, while help with errands is a hope), the share (hours, trips, or an amount of money that someone has actually agreed to), and the name of the person who answers when that line slips.
Ask whether the shares measure the same kind of work. A sibling who covers the groceries and a sibling who makes the long drive every week are both contributing, but a list that mixes them without saying how they convert will be fought over later.
Check what happens when a line stops working
Life moves. Someone changes jobs, moves farther away, has a new baby, or gets sick. Before you sign, ask what the paper says about a line that can no longer be carried. Good agreements name a backup and a way to hand a line over. Weak ones assume everyone stays exactly where they are.
Ask who can change the agreement and how. If the answer is whoever feels strongest about it, you do not have an agreement yet.
Check the copies and the original
Every sibling should have a copy they can reach without asking. Decide who keeps the signed original and where it lives, and write that location on the first page. A split that only one person can find is a split only that person can enforce.
Check the review date
Pick the date you will look at the paper again before you leave the meeting, and write it at the top. Your mother's needs and your family's circumstances will both shift. An agreement nobody reopens quietly turns into one daughter's job description.
Know what the paper does not do
A family agreement divides labor and money among siblings. It does not give anyone authority to make medical or financial decisions for your mother, and it does not replace the formal papers that do. If you are wondering who signs for her bank, makes care choices, or speaks for her with her doctor, ask a Missouri attorney how those roles are set up, and start with the Local help page for places to begin. Keep the family agreement honest about its limits so nobody mistakes a list of chores for legal authority.
What to bring to the next meeting
Bring your running record of trips, receipts, and hours, along with the list of tasks as they really happen rather than as everyone remembers them. Then ask each sibling to read the draft aloud and initial only the lines they can actually keep. The lines nobody will initial are the ones to talk about first, and they are the ones that would have broken the split anyway.
