In a stepfamily, decisions about assisted living follow the same order as in any family. Your parent decides if they can. If not, the person they named in a health care power of attorney or proxy decides, as that document allows. Without documents, state default surrogate laws apply. These laws list who can decide for your parent, and in most states a spouse ranks ahead of adult children. An elder law attorney can explain your state's rules.
Key facts
- As of December 2022, 46 states had default surrogate consent laws, and Massachusetts, Minnesota, Missouri and Rhode Island did not. (ABA Commission on Law and Aging, 2023)
- In most states, the default order for health care decisions when there is no proxy is the spouse (unless divorced or legally separated), then an adult child, then a parent, then an adult sibling. (ABA Commission on Law and Aging, 2014)
- The American Bar Association notes that without a power of attorney, a court may need to appoint someone, through guardianship or conservatorship. (American Bar Association, n.d.)
- Under the FMLA, the federal family and medical leave law, the Department of Labor's definition of parent includes a stepparent. (U.S. Department of Labor, 2023)
- The Family Caregiver Alliance names social workers, family therapists, geriatric care managers, doctors and clergy as neutral parties who can help when sides form. (Family Caregiver Alliance, 2011)
Your dad remarried twelve years ago. Now he's had a stroke. His wife wants him home with aides, and you and your sister think he needs assisted living. Or maybe it's the other way around. Your stepmother is the one who needs care, your dad is worn out, and her children from her first marriage have opinions. Everyone loves the same person, and nobody is sure who gets the final word.
This post sorts out who decides and what each person's role usually is. It also covers how to keep a blended family working together through a move. It's general information, and the details will depend on your parent's documents and state law.
The order of authority
The order of who decides is the same whether or not a family is blended:
- Your parent, if they can make their own decisions and say what they want. A second spouse and adult children from a first marriage can give advice, and your parent makes the call.
- The documents your parent signed. The National Institute on Aging describes two. A durable power of attorney for health care names a health care proxy to decide if your parent can't. The other is a durable power of attorney for finances. Your parent may have named their spouse, a child, or different people for each.
- State default surrogate law, if there are no documents. A surrogate is someone who decides for your parent, and these laws set the order. The ABA Commission on Law and Aging reported that 46 states had default surrogate consent laws as of December 2022. Massachusetts, Minnesota, Missouri and Rhode Island did not.
- A court, as a last resort, through guardianship or conservatorship. The American Bar Association notes that without a power of attorney, a court may need to appoint someone. Your parent may not get to choose who.
Step one for any family is to find out whether your parent has signed a power of attorney or health care proxy. If so, get a copy. The moving checklist puts any elder law appointment in the first week of a move, because these appointments can take a while to get. If your family is still deciding who should hold that role, see which sibling should be power of attorney.
Why the spouse often comes first
When there's no health care proxy, state law decides who can make medical decisions. The ABA Commission on Law and Aging's 2014 overview found that in most states the order is: the spouse (unless divorced or legally separated), then an adult child, then a parent, then an adult sibling. That usually puts a stepparent ahead of adult stepchildren, and even ahead of your parent's own children.
The same overview notes two things stepfamilies should know. First, the legal order may not match real life in families shaped by divorce and remarriage. Second, several people can share the same rank, most often adult children. In that case, the most common rule was to let providers rely on a majority of them. Many states also offer a route to court for disputes.
These laws generally cover health care decisions. Money is separate. Signing a residency agreement or paying from your parent's accounts usually needs authority over finances. Laws also change, and some states have recently widened the list of who can serve. Check your state's current rules with an elder law attorney, or see when to hire an elder law attorney.
Common stepfamily situations
| Situation | Who usually leads | Your role |
|---|---|---|
| Your parent needs care and your stepparent is healthy | Your parent, with their spouse as closest partner | Offer research, tours and practical help, and share concerns directly with both |
| Your stepparent needs care and your parent is the caregiver | Your stepparent, their spouse (your parent), and their named agents | Support your parent, who may be exhausted, and coordinate with your stepsiblings |
| Both need care | Each person for themselves, then their own documents | Help them weigh moving together or separately |
| Your parent can't decide and named you as health care proxy | You, within the document | Involve your stepparent and decide as your parent would have wanted |
| Your parent can't decide and no documents exist | Often the spouse under state law | Talk to an elder law attorney before a crisis hardens positions |
If both parents may move, assisted living for couples covers the options.
Getting everyone the same information
Stepfamily conflicts can start with uneven information. The spouse hears from the doctor, and the children hear it secondhand. Family Caregiver Alliance has a fact sheet on caring for a parent with siblings. It notes that step-siblings may have no model for working together. It suggests having a professional assess the parent's condition and sending the report to everyone.
Doctors need permission to share. The NIA explains that by law you need written permission to get a person's medical information, unless they're with you and able to agree. Ask your parent whether they'll sign permission for both their spouse and their children. For the details, see HIPAA authorization for family.
One plan both sides of the family can see
Parent Move Plan is a shared Google Sheet with 79 move tasks on real dates counted back from move-in day. The plan also has a Team tab where a stepparent, children and stepchildren can each own tasks. It also adds a weekly check-in agenda and a shared costs log, so nobody is working from a different version of events.

This is where stepfamily moves get hardest, and where a professional's advice matters most. Questions to take to an elder law attorney:
- Whose money pays for assisted living: your parent's separate funds, joint funds, or both?
- How would paying for one spouse's care affect the spouse who stays at home?
- Is there a prenuptial agreement or trust? Does it address long-term care?
- If Medicaid might be needed later, how do your state's rules treat a married couple?
- Who owns the house, and what happens to it if one spouse moves out?
Belongings raise feelings too. University of Minnesota Extension notes that choices about personal things affect stepsiblings and spouses from remarriages. It adds that these choices are often harder than decisions about money. Your stepparent may still live among the things your parent brought into the marriage. Take those decisions slowly and together, starting with what your parent wants.
Making decisions together anyway
Knowing who signs won't keep a family working together. A few habits help:
- Meet with everyone, including the stepparent and stepsiblings. A set agenda keeps it on track, like the one in a family meeting agenda for a parent's move.
- Start with your parent's wishes, in their words, before anyone's opinion.
- Take the stepparent's exhaustion seriously. A spouse doing daily care may see the move very differently from children who visit.
- Bring in a neutral party if sides form. FCA names social workers, family therapists, geriatric care managers, doctors and clergy.
- Know the FMLA detail. FMLA is the federal family and medical leave law. The Department of Labor's definition of parent under it includes a stepparent. So an eligible stepchild may be able to take leave to care for one.
If you're raising it with your stepparent, you might start like this:
"You're with Dad every day, and I know how much you're carrying. We both want Dad safe and as happy as he can be. Could we sit down together, with Dad if he's up to it, and look at the options side by side? We'll back whatever he decides."
This article is general information, not legal advice. Rules on surrogates, a spouse's money and Medicaid differ by state. Talk to an elder law attorney in your parent's state.
Frequently asked questions
Does a stepparent have the right to decide on assisted living for my parent?
If your parent can make decisions, your parent decides. If they can't, the person named in their health care power of attorney or proxy has authority within that document. Without those documents, many states' default surrogate laws put a spouse ahead of adult children for health care decisions. An elder law attorney in your parent's state can explain what applies.
Can adult stepchildren make decisions for a stepparent?
Only if the stepparent named them in a power of attorney or health care proxy, or state law gives them a place in its surrogate list. Stepchildren often aren't the default decision-makers. They can still help, and a stepparent can sign permission for doctors to talk with them.
What if my stepparent and I disagree about my parent's care?
Start with what your parent wants and what their documents say. Share the same medical information with everyone, meet together, and consider a neutral facilitator such as a social worker. If you believe your parent is at risk, talk to an elder law attorney or contact Adult Protective Services through the Eldercare Locator.
Can I take FMLA leave to care for my stepparent?
Possibly. The Department of Labor's definition of parent for FMLA includes a stepparent. The usual eligibility rules still apply, and the stepparent must have a serious health condition.
