When a Montana resident passes away without a valid will, state law determines who receives their property. This process is called intestate succession, and it follows a specific hierarchy that may not match what the deceased person would have wanted. The rules apply to assets that would normally pass through probate. This includes real estate owned solely by the deceased, bank accounts in their name alone, and personal property without designated beneficiaries. Assets with named beneficiaries or joint ownership typically bypass this process entirely.
How Montana Law Distributes Property
Montana’s intestate succession statute creates a priority system based on family relationships. The distribution depends on which relatives survive the deceased person. If you’re married with children who are all from that marriage, your spouse inherits everything. This changes if you have children from a previous relationship.
When You Have A Spouse And Children From Different Relationships
The estate gets divided. Your spouse receives the first $150,000 plus half of the remaining estate. Your children split the other half equally, regardless of which relationship they came from.
When You’re Unmarried
Your children inherit everything in equal shares. If a child died before you but left their own children, those grandchildren take their parent’s share. No children? Your parents inherit the entire estate. If your parents have already passed, your siblings become the heirs.
More Distant Relatives
Montana law keeps moving through the family tree if you have no spouse, children, parents, or siblings. The estate passes to:
- Nieces and nephews
- Grandparents
- Aunts and uncles
- Cousins
If absolutely no relatives can be found, the property goes to the state. This rarely happens, but it’s possible.
Common Misconceptions About Intestate Succession
Many people assume their longtime partner will automatically inherit if they’re not married. Montana law doesn’t recognize common-law marriages formed after 1985, so unmarried partners receive nothing through intestate succession. Another frequent misunderstanding involves stepchildren. Unless you legally adopted your stepchildren, they have no inheritance rights under intestate law. The same applies to foster children. A Billings probate lawyer at Montana Elder Law can help families understand these distinctions and address potential conflicts before they escalate.
Why Intestate Succession Creates Problems
The statutory distribution formula is rigid. It can’t account for estranged family members, relatives who need more support than others, or specific wishes about sentimental items. Your estate might go to someone you haven’t spoken to in decades while excluding the friend who cared for you during your final years. The law doesn’t consider these relationships. Intestate succession also requires a full probate process, which takes time and money. Your family will need court involvement even if your estate is relatively simple.
The Role Of Probate Court
When someone dies intestate, the court appoints a personal representative to manage the estate. This person handles debts, files tax returns, and distributes assets according to state law. Family members sometimes disagree about who should serve in this role, creating additional delays and legal fees. A Billings probate lawyer guides personal representatives through their responsibilities and helps resolve disputes.
Taking Control Of Your Estate
Creating a will lets you decide who inherits your property. You can leave assets to friends, charities, or anyone else you choose. You’ll also name your own personal representative instead of leaving that decision to the court. Other planning tools can help you avoid probate altogether. Transfer-on-death deeds, payable-on-death accounts, and trusts let you control asset distribution while keeping your estate out of court. Montana Elder Law, Inc helps families create estate plans that reflect their actual wishes and protect their loved ones from unnecessary legal complications. Taking action now prevents the rigid application of intestate succession laws and gives you peace of mind about your family’s future.
Montana Intestate Succession FAQ

What does intestate succession mean?
It is the statutory formula that applies when there is no will, or when a will fails to cover part of an estate. The court follows a fixed order of relatives. Personal wishes, promises made during life, and family circumstances carry no weight in that calculation.
Which assets does it control?
Only property that would pass through probate: real estate titled solely in the deceased person’s name, individual bank accounts, vehicles, and personal belongings without a named recipient. Jointly owned property and accounts with a designated beneficiary transfer outside the process entirely.
What does a surviving spouse receive?
It depends on who else survives. A spouse may take the whole estate, or a set dollar amount plus a share of the balance when parents or children from another relationship are in the picture. Montana’s statute on the share of a surviving spouse sets out those amounts.
What happens in blended families?
The spouse’s share drops when the deceased leaves descendants who are not also the spouse’s children. The balance passes to those children. This is where intestate distribution most often surprises families, because the surviving spouse may end up sharing the home’s value with stepchildren.
Who inherits with no spouse or children?
Parents come next, then siblings and their descendants, then grandparents, aunts, uncles, and cousins. Montana law works down the family tree in a set order until someone qualifies.
Can property end up with the state?
Yes, though it is uncommon. If no qualifying relative can be located, the estate passes to Montana. Most cases involve at least a distant cousin, but the outcome is possible for someone with no traceable family.
Do unmarried partners inherit?
Not through intestate succession. A partner without a legal marriage receives nothing under the statute, regardless of how long the relationship lasted or who provided care. A will, beneficiary designation, or joint title is the only way to change that.
What about stepchildren?
Stepchildren and foster children have no inheritance rights unless legally adopted. Families who assume otherwise are often surprised during administration, when the personal representative has to follow the statute rather than the household’s actual relationships.
Who manages an intestate estate?
The court appoints a personal representative to collect assets, pay debts, file tax returns, and distribute what remains. Relatives sometimes disagree about who should serve, which adds delay and expense to an already slow process.
Our page on probate and estate administration explains what that role involves.
How can this be avoided?
Common tools include:
- A valid will naming heirs and a personal representative
- A revocable living trust
- Transfer on death deeds for real property
- Payable on death designations on accounts
- Current beneficiary forms on retirement and insurance
What does an intestate succession lawyer do?
Applies the statute to the actual family tree, identifies and locates heirs, guides the personal representative through filings and deadlines, and handles disputes over who serves or who qualifies as an heir.
The statute is a default, not a plan, and it rarely matches what people would have chosen. To draft a will or handle an estate left without one, contact Montana Elder Law, Inc.
